So Talga graphite is superior to all other graphite in quality and performance. But where is the independent proof of this?
Its time to see the results from outside testing., Not just taking MT at his word. MT needs to justify the top end price of Talga graphite.

There is definitely independent proof that Vittangi is a superior resource and Talnode-C outperforms benchmark commercial anode.

There are a number criteria which impact the performance of graphite anodes; carbon source, particle size, shape, coatings etc.


"Different active materials and particle sizes have been investigated in numerous studies. The effect of different graphite materials on the cycling stability, C-rate capability and intercalation behavior were investigated.3, 25, 26 They found out that the material type, particle size, porosity, electrode thickness and loadings have an influence on the battery performance. For example, coarser particles can cause poor intercalation kinetic and slower diffusion rate. Buqa et al.25 investigated three different graphite particle sizes (6 μm, 15 μm and 44 μm) and showed that smaller particles can achieve better capacity retention. Furthermore, Buqa et al.,27 Goers et al.28 and Spahr et al.29 showed that the exfoliation, SEI formation, as well as the graphite structure are influenced by the overpotential, current density and active surface area, which are induced by different types of graphite material and particle size."

The Vittangi graphite resource is the highest grade JORC resource globally and was formed from a 2 billion year old deposit of microbes (Cyanobacteria) which were naturally crystallised at low temperatures and high pressures to generate micro-crystalline structures. The super-homogenous highly crystalline flake graphite is naturally sized for anodes (10- 20μm), and is highly conductive (there is even a video of MT passing a current through a chunk of the graphite). The narrow flake distribution also generates high processing yields of 90%, whereas the common yield is ~50%. The nature of the graphite was confirmed in a 128 page independent report by the CSIRO and is also outlined in the DFS which is subject to strict JORC regulations.

The superior performance of Talnode-C isn't all just MTs word either. Talga have released Talnode-C test results (which are subject to dsiclosure regulations), and there have also been a number of indepedent tests conduted showing Talnode-C is superior to commercial benchmark anode.

Tests of Talnode-C were done at the leading global independent facility of Warwick Manufacturing Group (“WMG”), part of the University of Warwick’s Energy Innovation Centre, and showed significant performance enhancements against commercial benchmarks.

A range of Li-ion battery pouch cells were fabricated using Talga’s graphite anode and commercial nickel-manganese-cobalt (“NMC”) cathodes, utilising standard industrial roll to roll processing conditions to prepare large format (A5) cells. The reference commercial anode cell was prepared under the same conditions, with identical weight inside the cells and paired with the same type of NMC cathode.

Pouch cell performance at WMG indicated significant enhancements for Talga anodes:
  • 20% higher capacity (total energy)
  • 20% higher power (fast charge/discharge)
  • No capacity fade after 300 cycles (>99% energy retention)
  • 94% first cycle efficiency
  • Successful scale up - from half coin cells to commercial size pouch cell

There was also an engagement with IV Electrics (formerly Italian Volt) who conducted benchtop tests of Talnode-C designed to replicate extreme real world conditions of the “Stelvio” Italian Alpine mountain road to simulate high performance of the “Lacama” motorcycle battery pack.

Results confirmed that Talnode-C cells outperforms the endurance of market leading commercial cells by up to 36%, and also confirmed the fast charge, high power and low temperature properties in real-world applications.

There were tests conducted at a leading Japanese battery institute where Li-ion batteries using Talnode-C were subjected to performance tests under a range of temperatures including freezing conditions.

The tests found:
  • Retention of 100% capacity and 100% cycle efficiency at freezing temperature (0°C)
  • Out-performance of market leading commercial anode products
Source:
In tests conducted at a leading independent European battery test facility, Li-ion batteries using Talga’s anode product were subjected to high charge conditions and benchmarked against a global leading commercial anode product (“CAP”).

The test results show Talga’s anode product significantly outperformed the CAP across a range of charge rates, and achieved very high charge capacity of >300mAh/g at an ultra-fast charge rate of 20C (see Fig 2 for details and Glossary for technical terms).

In general terms, this anode performance enables a Li-ion battery to be charged from 0% to 100% in 3 minutes without losing its capacity.

Source: https://cdn-api.markitdigital.com/a...access_token=83ff96335c2d45a094df02a206a39ff4

It would be great to have confirmation of pricing but Talga have already independently proven the product is superior and are now in final stage qualification and commercial negotiations with many battery manufacturers and OEMs. These pricing negotiations will be commercial in confidence and subject to NDA but I expect we will find out soon enough.

"A domestic raw material supply chain is essential for Europe’s battery ambitions​


Energy

11th August 2022


Raw materials

Ilka von Dalwigk, Policy Manager at EIT InnoEnergy, emphasises the importance of developing a domestic battery raw materials supply chain in Europe.​

Europe can proudly and accurately call itself a climate leader in a number of spheres. The ‘Fit for 55’ package is the latest boost to Europe’s green ambitions, confirmed within the transport sector by a positive vote of the EU Council in June. The Council voted to increase CO2 reduction targets for new cars and new vans (55% instead of 50% for cars and 50% for vans by 2030), and also stood firm on the ICE ban in 2035. Consequently, recent forecasts point to an 80% market share for electric vehicles (EVs) in Europe by 2030.
The battery industry is responding to these projections. In just a few years, the European Battery Alliance (EBA), managed by EIT InnoEnergy, has turned Europe into a hotspot for investments along the entire battery value chain, closing the gap between our global peers. Europe is now on track to become the second-largest battery cell producer in the world, behind China.
This is staggering progress. Northvolt, Europe’s ‘first homegrown gigafactory’ and EIT InnoEnergy investee, only began construction in 2019 and recently completed its first delivery to a major car manufacturer. Our estimates suggest it will be joined by a further 40 additional gigafactories by 2035.
However, we must ask where we get the raw materials from to make these batteries. The EU is currently almost entirely dependent on importing the necessary materials for batteries. This extreme dependency creates several risks and makes the supply chains for the battery industry highly vulnerable.
First, it makes it difficult for European battery makers to guarantee that the materials they use have been strictly responsibly sourced, both in terms of sustainability and human welfare. The EU has among the world’s strictest industrial emissions and environmental requirements, and it cannot always be guaranteed that materials mined elsewhere have been produced according to the same standards. Imports from distant origin countries also add significant shipping-related emissions.
Furthermore, the recent war in Ukraine and the accompanying economic shocks have shown the fragility of global supply chains and the risks of relying purely on imports. To take just one example: Russia accounted for 7.2% of the global supply of nickel in 2021 – an important element in battery manufacturing.
Though complete self-sufficiency is unrealistic, these factors show that Europe can significantly reduce its risks, protect its opportunities, and advance its climate leadership by developing its own domestic resources and thereby strengthening its domestic battery materials supply chain.

A continent rich with raw materials​

Some of the most important materials for today’s battery compositions are lithium, manganese, graphite, nickel, and cobalt. Fortunately, there are sources for all of them within Europe’s own borders.
The EU has several promising lithium projects under development, the most important element for current battery technologies. One of the most interesting is located in Germany, where Vulcan Energy has pioneered a new lithium extraction technique. Here, geothermal brines are used to produce lithium for the European battery industry with zero carbon emissions, matching the EU’s stringent climate agenda.
There are currently about ten potentially viable lithium projects under development in Europe from Finland in the north, through Germany, Austria, and Czechia in central Europe, to Spain and Portugal in the south.
Rene Kleijn, Associate Professor at the Institute of Environmental Sciences (CML) at Leiden University, stated: “If all these plants become operational, it would probably be enough for our own supply.”
A positive example of producing valuable raw materials from a secondary source is the Chvaletice Manganese Project in Czechia – part financed and supported by EIT InnoEnergy. The innovative project is reprocessing the tailings of a previously decommissioned mine to create a source of high-quality manganese – offering a dual environmental benefit of recycling a waste material and creating a supply for European battery makers. As for nickel, there are resources to be found in the Nordics, including the EU’s largest nickel mine operated by Terrafame in Finland. Cobalt is often co-located with nickel, and a recent study identified 104 such deposits for cobalt exploration, including 79 in Norway, Finland, and Sweden.

Graphite is another important ingredient for battery production, being the key material for anodes. There are two promising projects that intend to mine graphite and produce battery anode material, one in Norway and another one in Sweden.
It is therefore not a lack of available resources that is holding Europe back from a domestic battery material supply chain.

Hurdles to overcome​

Building a domestic supply chain is not an easy undertaking. There are significant challenges to developing the European battery mineral supply chain, particularly for greenfield sites which have not hosted mining or heavy industry before. In fact, our own estimates of supply from domestic resources have decreased due to projects being delayed from starting production, as well as stopped projects such as the Jadar mine in Serbia, that alone was set to account for almost 30% of Europe’s lithium supply by 2030.
Lack of public acceptance can be a particularly challenging bottleneck for securing EU production of raw materials. Only in December 2021, thousands of Serbian protestors took to the streets of Belgrade to push back against Rio Tinto’s planned Jadar lithium project and Zijin Mining’s Čukaru Peki copper and gold mine, citing concern for nature. Improving the social, ethical, and environmental sustainability of the raw materials sector is thus a relevant objective to develop a battery supply chain in Europe.
However, we cannot afford extended project delays. We must therefore find a way to accelerate and smooth the permitting process without compromising on environmental standards to reduce time and risks. Ways to do so could include adopting parallel processes rather than sequential ones, and harmonising rules for public consultation and environmental impact assessment. Today, it can take anywhere between three and ten years to secure all relevant permissions, making it extremely difficult to attract investors for projects.
Another major challenge is finance, including a lack of public funding. Here, Europe needs to develop an upgraded toolbox to support and de-risk investments in raw and processed battery materials. One important step in this direction is the Critical Raw Materials (CRM) initiative that was announced formally in the REPower EU communication.
This clearly underlines that we should not compromise on either environmental standards or treatment of workers in Europe. Quite the opposite: as discussed above, these high standards are precisely part of the reason we want to onshore battery mineral extraction in the first place.

Lessons from abroad​

These challenges are significant, but they are not insurmountable. We can look to other western developed nations like Australia and Canada for guidance on how to do so.
Canada, for example, has established good protocols and processes for interacting with Indigenous peoples – something that needs to be developed in the EU, but that will be relevant when projects in Europe’s northern reaches touch the lives of the Sámi people, for instance. Similar approaches may well be adaptable to other stakeholder negotiations, such as when proposed lithium mines in Portugal abut protected areas where the local population maintains traditional farming methods.
raw materials

From Australia, we can learn the lessons of a country that has invested heavily in improving environmental, social, and governance (ESG) standards for its mining industry. For example, the Towards Sustainable Mining framework aims to improve ESG performance using independently verified standards.
Crucially, both countries have supported their mining industry in modernising using public funds – something the EU has historically done well, such as through the Horizon 2020 programme.

Changing chemistries​

Another way to ease the pressure on the European battery raw materials supply chain is to use materials more efficiently or change the materials the batteries use. This can be done in several ways. Semi-solid or solid-state batteries, as developed by the Spanish Basquevolt initiative, will enable more energy dense batteries, while the Swedish company Altris chose a different path and is developing batteries with a chemistry based on sodium. Other projects look at substituting some of the most critical elements.
For example, citing its high toxicity and ethically problematic supply chain, the COBRA (CObalt-free Batteries for FutuRe Automotive Applications) project is using Horizon 2020 funds to research and develop a next generation of cobalt free batteries. Though there is research with the same goal happening around the world, with major players like Tesla involved, this is an opportunity-area for Europe to excel – few other places can match Europe for density of world-class universities and research institutions, boosted by initiatives like BATTERY 2030+, Batteries Europe, and BEPA.

Changing sources of battery materials​

This strength in technological development is already bearing fruit in another way too – that of recycling and recovering battery materials, in line with the EU’s emphasis on the circular economy.
There are multiple ways to approach battery recycling. First, the batteries themselves can be reused for other applications. For example, Enel Group has employed 90 used Nissan Leaf batteries in an energy storage facility in Melilla, Spain, finding a ‘second life’ use for the batteries themselves.
Then, there is the option to recover and recycle the component materials. This is a multi-stage process which is attracting major interest from around Europe, also driven by dedicated measures for recycling in the proposal for an EU Battery regulation.
For example, energy giant Fortum in Finland claims that its two stage process allows for 80% of the battery to be recycled. The battery is mechanically processed to separate out the plastics, aluminium, copper, and ‘black mass.’ The ‘black mass’ is what contains the valuable battery metals, and is the focus of the second stage: hydrometallurgical processing that recovers up to 95% of the valuable metals.
This process has already been successfully demonstrated by Northvolt who produced its first battery cell with 100% recycled nickel, manganese, and cobalt by the end of 2021 and now aims towards scaling-up recycling facilities in Sweden. VW is working on processes that will allow it to recycle battery materials multiple times, creating a closed loop together with several partners.
An easier process is pyrometallurgy, however, this loses some of the lithium so may not prove to be the long term solution to the problem.

Changing perceptions​

Perhaps the biggest hurdle to come, however, is that of public perception. The Jadar lithium project will not be the last European mining project to face opposition, and the public must be won onside.
This will take concerted efforts from various industry stakeholders, but it can be done. First, we must emphasise the benefits of a strengthened European mining sector. Direct and indirect employment should be a powerful argument at a time of global economic uncertainty, especially for communities that once relied on mining only to be left behind by economies that diversified away from the practice.
image-4-iStockFritz-Jorgensen-1350394256-300x164.jpg

We must also emphasise that mining need not be a dirty industry. Indeed, the minerals that will underpin the energy transition need to come from somewhere, and by onshoring that supply chain to Europe, we can guarantee that environmental protections will be high, while also reducing shipping and transportation related emissions versus imports. We cannot close our eyes against environmental impacts simply because they happen somewhere else.
On a more subtle note, we need to remind the people of Europe that mining is not alien to our region. Today, it may be that mining is often outsourced to other nations, however mining has taken place in Europe since the stone age – it is part of our shared culture and history that can be celebrated, having formed the basis for our industrialisation and many technological innovations.
Making that case – uncompromising on environmental and social standards but unambiguous about mining’s potential to help Europe, is essential to unlocking a European battery raw material supply chain. If we can combine that with a strong recycling industry and research and development into novel battery chemistries, then we can make Europe a true leader in battery technology and the energy transition.

I thank you both!
SAP used to have a bad reputation a few years ago because it is very complex and expensive with running costs. But I know that a lot has changed. One of them once tried desperately to make the advantages of their ERP system palatable to me and mentioned many times that it no longer had anything to do with the old one. However, an ERP system is in any case a welcome step in the right direction. Perhaps with the industry leader it is also easier to connect to the distribution systems of the OEMs. But that is just a guess. I don't see it as a nice expensive bonus but as a sign that they are getting ready to deliver. It also makes it much easier to manage customers. A professional step! It's also good that they installed it right at the beginning. Later on, data migration would become more and more difficult and costly.

Fun fact - Mark is also a world renowned palaeontologist.

He discovered one of the most important dinosaur fossils in a century with a Guinness world record for the best preserved dinosaur. He was then embroiled in a scandal as one of his colleagues tried to steal the fossil.






Back from vacation, i have finally time to read a bit more about what was going on here the last week. :) Interesting back story about Mark. If I ever meet him, i will have to bring it up :) dinosaurs are some of my all time favorite topics since I was 5, and my son is the same :)

Thanks for your explanations! You are absolutely right that he is a respected geologist and knows exactly what he is doing. And for the others who don't know the company for so long:

"INSIGHTS FROM INDUSTRY

Developing the World’s First Industrial Graphene Supply​

Interview conducted by Alexander ChiltonJul 30 2015

ImageForArticle_4109(5).jpg

Mark Thompson, Managing Director of Talga Resources Limited, talks to AZoNano about their unique, simple and cost effective process to liberate graphene directly from its large high quality graphite ore deposits.

Could you provide our readers with an overview of Talga Resources Limited and explain how the company has changed since it floated on the Australian Securities Exchange (ASX) back in 2010?

We started off as a gold focused company and we recognised the graphite space becoming of more and more economic importance in 2011.
We secured our graphite projects in Sweden in 2012 and it was during the development of our flagship project at Vittangi that we discovered that both graphite and graphene could be liberated from the ore in a rather special way in early 2014.
That leads us nicely to where we are today in 2015. We celebrated our 5th year anniversary last month, with the company having a market value of approximately 7 times of when it started.

Mark, you personally entered the graphene processing industry from a geological background, having spent more than 20 years working on mineral exploration and mining management. How has your previous experience influenced the way in which Talga views the graphene processing market and the way it operates within it?

Certainly as graphene is a material that has been largely difficult to manufacture and is still developing in its market, it means that it is an industry which is weighted towards more scientific knowledge when it comes to the management and development of graphene companies. I think my experience in a geology and mineral career has allowed me to have a more complete view of the material process from the mine to the market.
ImageForArticle_4109(4).jpg

I find that many people in the graphene sector from the academic side did not understand where the graphite precursors came from depending on how they were making their graphene. If they were making it from a natural graphite source I found that they did not understand the quantity of steps, the expense and the environmental footprint of their graphite supply before they’d even begun to commence a graphene production process.
Coming from the other side of it, it allows you to develop an objective view of natural advantages through the whole process from the first cost and the natural abundance of materials through to the way that feeds into the economic side of graphene production. I have found this an advantage to date.

Why is it very important to carefully consider the source material you use when producing and processing graphene? What are the advantages of doing so in terms of the cost of the production process and the quality of the end material?

There are fundamentals such as crystallinity and grain size that can feed into any resulting graphene process but I find mostly that if you consider carefully the source material, then that sets up the economic conditions for the graphene production process.
For example, if you look at what has happened in the lithium production market. For many years the way we produced lithium was from hard rock sources and there has been in more recent years a greater focus on saline sources of lithium. This is much more economic as a source of lithium than hard rock, so the source supply of that material changes your economic costs and your margins when producing it.
If you can source a graphitic precursor that has got as big a benefit as, say liquid versus hard rock, or in our case things like crush and grind versus another method which liberates the graphene, you see that an economic condition that is more advantageous than other pathways. That is why the source of the material is really the start of solving the problems that there has been in graphene production.

What do you believe sets Talga Resources apart from pure play graphene companies and gives you a true competitive advantage within the graphene market?

The main advantage is probably volume – as we make graphene almost as a by-product of our graphite mining, we can produce graphene on a scale than is more akin to graphite mining. By comparison to pure play start-ups, it is the sheer volume because we mine our source material, we are developing our source material and processing it in a way to suit another market – the graphene as I mentioned is almost like a by-product.
This allows us to produce massive volumes compared to what other companies can produce so it’s scalable and also means the cost basis is much lower than other routes. Also, fundamentally as a business model, the company can make money from its graphite assets as well as its gold, cobalt and other assets so Talga does not live or die by whether the graphene market commercialises or not at the speed which we hope it will.
The business model of the company runs very profitably on the standard industrial commodity supply of graphite and therefore we are not actually reliant on the commercialisation of the graphene market to make money, it just means that we will make more money if the market grows in the way in which we believe it will.

Talga Resources now has five 100% owned graphite projects in Sweden. Could you explain to our readers where these projects are geographically within Sweden and how the deposits vary by location?

All the deposits are in the north of Sweden, mainly in the Norrbotten district, which is one of the largest mining producing areas of the country. It has been the home of some of Europe’s largest iron ore, copper and gold mines for nearly one thousand years so it is clearly an area of Sweden with an active mining district.

ImageForArticle_4109(2).jpg


The deposits range from the highest grade technical resource in the world at nearly 25% at the Vittangi project to deposits which have resources down to 7% graphitic carbon grade ranges. The deposits at the five projects cover a complete range of sizes from less than 75 microns to 80% of them being bigger than 300 microns in size.
Probably more importantly, the particular process we use in an advantageous way to get the graphene and the graphite supply from the rock only covers two of the five projects. We have standard slate-graphite projects which can be developed into materials that would suit the full range of graphite specifications. Two particular projects are exceptionally high grade and they have been proven to liberate graphene as well as graphite in a unique, low cost and scalable way.

Last month (26th June 2015) Talga Resources announced the commencement of site works in relation to its trial mining program at the Vittangi graphite project. Could you summarise the latest developments on this project to our readers?

Related Stories​

We made a decision around 6 months ago, as part of the development towards a full scale mine in Sweden which would take between 2 and 3 years, that in the meantime we would undertake some trial mining at the Vittangi project to prove the methodology we propose and that we can therefore treat larger amounts of material through this process. This will allow us to not only prove what is a world first in the mining to processing method but allows us to confirm that this method can be scaled up to full scale production.
It has also provided the opportunity to gain large channels of graphene to supply to the market where companies and products which we have identified with large volumes need quite large sample sizes to accelerate the development of the product. That is why we are undertaking trial mining as well as pilot plant processing in Germany so that we can advance the market faster.

Talga Resources recently secured a site in central Germany for a demonstration plant to process your high-grade graphite ore from your deposits in Sweden. Why did you decide to construct a pilot plant there rather than in Sweden? What are the advantages of choosing this location?

There are many advantages to being based in both countries. We chose the deposits in Sweden because they are exceptional deposits and quite unique in the world in the way they work and their exceptionally high grade. Sweden has also got very advantageous tax and mining laws. The infrastructure and low cost power in Sweden is really second to none anywhere in the world.
It really is a great place to be developing and producing our precursor graphite material but we also recognise that north Sweden is quite far away from end users who may be in Europe and the analytics which are required in order to work with quite high precision graphene.
We have several research programs running on the graphene production process and utilising graphene in products in central Germany. There was a real speed benefit as there were government buildings available to lease which we could turn into a pilot plant. There are also quite generous research and development concessions from the local government.

ImageForArticle_4109(1).jpg


It was faster and cheaper to build the pilot processing plant in Germany and transport the material down from Sweden than to construct all of those facilities in north Sweden in the time frame we wanted. The time frame we are talking about here was 4 months – we have got to the stage we are at now in 4 months from the decision to do it so it needed to be very rapid by going to the Thuringia area of Germany.
An additional benefit is that the research programs give us access to world class analytical facilities for the characterisation of the material and the integration of the graphene into customer’s products, which means that it can happen a lot faster. It also provides a facility where end users can see what we are doing and get some comfort from the fact that we have a consistent high-quality process and a real industrial example of graphene production rather than something theoretical.

When do you believe the pilot plant in Germany will be operating at full scale? Will this remain your main processing plant or do you have plans to move to an alternative location in the long term?

The German pilot plant will be scaling itself up through several phases until it is at full scale in 2016. It will be our primary processing plant for approximately two years until our site in Sweden is ready to go into full scale production and then everything will shift to Sweden.
The German plant is expected to continue to operate in some sort of R&D or even small retail type way but the bulk of production will shift to Sweden and the material will be processed on site. In the meantime, it is certainly cheaper and faster to do it in this way.

What are the main markets and application areas which you are targeting with the graphene you produce?

Because of our potential for volume, we are focusing on graphene as an additive. Within that sphere are things like composites, 3D printing inks, conductive inks, paints, anti-corrosion coatings, galvanic applications on to steel, plastics and polymers such PET material or packaging material.
We are focussing mainly on the additive applications which have not only large volume but also good margins and are current products. We do not require new products to be created which do not exist yet, we just looking at making current products better.
We see this as the fastest pathway for graphene to commercialise and its one that we feel is a lot better developed behind the scenes than the media has been picking up on because there is a focus on well-hyped futuristic applications of graphene rather than the fundamentals of how it can affect every day materials.

What do you believe is the biggest challenge which the graphene industry has to overcome before this 'wonder material' can be fully commercialised in the near future?

I differ from a lot of people in industry at this point who keep seeking a killer application. I actually think that to just focus on one single graphene only application is a little furphy. I have seen many trial products that have not been able to continue onto production because of the lack of volume in the supply of graphene and the associated high costs of the material.
I see volume and costs as the chicken to graphene’s egg. Most people have been waiting for graphene but they have not solved the volume or the cost problem. When you solve these problems then you can enable all sorts of graphene applications to occur and a couple of those might turn out to be killer applications. I see the production side as being the main hold-up.
When you have a material like graphene with extraordinary properties such as strength, conductivity, transparency in some applications amongst others, and it seems that there is quite an abundance of evidence in how it can affect everyday materials then you do not need a killer application, you just need to solve the supply problem.

I don't know. It is not mentioned in the DFS but still listed in the QR under Tenement Holdings. Maybe it's not productive or hard to tap into. But I think Vittangi is big enough and as backup still Jalkunen. First put the foot in the pit. This week the trucks should be bumper to bumper. If each one only holds 25t that's a lot of driving. I am very curious if we will see pictures or videos of the processing on the new/converted site south of the mine.

So Talga graphite is superior to all other graphite in quality and performance. But where is the independent proof of this?
Its time to see the results from outside testing., Not just taking MT at his word. MT needs to justify the top end price of Talga graphite.

I am chasing this question for quite some time now and it seems we will not get the information. It appears that battery component performance is a highly guarded secret among all players. Any measurement depends on the cicrumstances and what it is compared with in the first place as all statements seem to be relative. This is the same for all players that I have seen so far. Its also never disclosed what basis each product is compared against, making it impossible to make relative statements. We simply dont know. I have no idea why this is such a tight regarded trade secret. There are plenty of research papers as well. While I am confident in reading research papers, I am not deep enough in the field of battery material science to interpret everything correctly. @catdog made a very good summary..

There is definitely independent proof that Vittangi is a superior resource and Talnode-C outperforms benchmark commercial anode.

There are a number criteria which impact the performance of graphite anodes; carbon source, particle size, shape, coatings etc.


"Different active materials and particle sizes have been investigated in numerous studies. The effect of different graphite materials on the cycling stability, C-rate capability and intercalation behavior were investigated.3, 25, 26 They found out that the material type, particle size, porosity, electrode thickness and loadings have an influence on the battery performance. For example, coarser particles can cause poor intercalation kinetic and slower diffusion rate. Buqa et al.25 investigated three different graphite particle sizes (6 μm, 15 μm and 44 μm) and showed that smaller particles can achieve better capacity retention. Furthermore, Buqa et al.,27 Goers et al.28 and Spahr et al.29 showed that the exfoliation, SEI formation, as well as the graphite structure are influenced by the overpotential, current density and active surface area, which are induced by different types of graphite material and particle size."

The Vittangi graphite resource is the highest grade JORC resource globally and was formed from a 2 billion year old deposit of microbes (Cyanobacteria) which were naturally crystallised at low temperatures and high pressures to generate micro-crystalline structures. The super-homogenous highly crystalline flake graphite is naturally sized for anodes (10- 20μm), and is highly conductive (there is even a video of MT passing a current through a chunk of the graphite). The narrow flake distribution also generates high processing yields of 90%, whereas the common yield is ~50%. The nature of the graphite was confirmed in a 128 page independent report by the CSIRO and is also outlined in the DFS which is subject to strict JORC regulations.

The superior performance of Talnode-C isn't all just MTs word either. Talga have released Talnode-C test results (which are subject to dsiclosure regulations), and there have also been a number of indepedent tests conduted showing Talnode-C is superior to commercial benchmark anode.

Tests of Talnode-C were done at the leading global independent facility of Warwick Manufacturing Group (“WMG”), part of the University of Warwick’s Energy Innovation Centre, and showed significant performance enhancements against commercial benchmarks.

A range of Li-ion battery pouch cells were fabricated using Talga’s graphite anode and commercial nickel-manganese-cobalt (“NMC”) cathodes, utilising standard industrial roll to roll processing conditions to prepare large format (A5) cells. The reference commercial anode cell was prepared under the same conditions, with identical weight inside the cells and paired with the same type of NMC cathode.

Pouch cell performance at WMG indicated significant enhancements for Talga anodes:
  • 20% higher capacity (total energy)
  • 20% higher power (fast charge/discharge)
  • No capacity fade after 300 cycles (>99% energy retention)
  • 94% first cycle efficiency
  • Successful scale up - from half coin cells to commercial size pouch cell

There was also an engagement with IV Electrics (formerly Italian Volt) who conducted benchtop tests of Talnode-C designed to replicate extreme real world conditions of the “Stelvio” Italian Alpine mountain road to simulate high performance of the “Lacama” motorcycle battery pack.

Results confirmed that Talnode-C cells outperforms the endurance of market leading commercial cells by up to 36%, and also confirmed the fast charge, high power and low temperature properties in real-world applications.

There were tests conducted at a leading Japanese battery institute where Li-ion batteries using Talnode-C were subjected to performance tests under a range of temperatures including freezing conditions.

The tests found:
  • Retention of 100% capacity and 100% cycle efficiency at freezing temperature (0°C)
  • Out-performance of market leading commercial anode products
Source:
In tests conducted at a leading independent European battery test facility, Li-ion batteries using Talga’s anode product were subjected to high charge conditions and benchmarked against a global leading commercial anode product (“CAP”).

The test results show Talga’s anode product significantly outperformed the CAP across a range of charge rates, and achieved very high charge capacity of >300mAh/g at an ultra-fast charge rate of 20C (see Fig 2 for details and Glossary for technical terms).

In general terms, this anode performance enables a Li-ion battery to be charged from 0% to 100% in 3 minutes without losing its capacity.

It would be great to have confirmation of pricing but Talga have already independently proven the product is superior and are now in final stage qualification and commercial negotiations with many battery manufacturers and OEMs. These pricing negotiations will be commercial in confidence and subject to NDA but I expect we will find out soon enough.

... but
  • 20% higher capacity (total energy)
  • 20% higher power (fast charge/discharge)
  • No capacity fade after 300 cycles (>99% energy retention)
  • 94% first cycle efficiency
  • Successful scale up - from half coin cells to commercial size pouch cell
1. and 2. : relative statements without knowledge of basis
3. very dependent on the charge conditions. Not saying these statements are wrong, just we cant know their true meaning without knowing everything surrounding the test. Also this result is invalidated by changing to the EVA plant production method and the fact that Talga now coates Talnode-C while the test results are without coating.
4. Thats normal
5. Thats great! But invalidated by the EVA and tests have to be redone.

Then these:
  • Retention of 100% capacity and 100% cycle efficiency at freezing temperature (0°C)
  • Out-performance of market leading commercial anode products
1. In my understanding, the capacity reduction in cold temperatures comes from the change in the electrolyte, not due to the anode. So might not have anything to do with Talnode-C. We dont know. Maybe I am wrong on this one, at moment, I remain sceptical. Also temperature performance is just a red hering as in reality its not a problem. The battery pack in an EV is heated by the waste heat of the motor while driving if its too cold. This will remove the efficiency loss due to cold weather without loss of performance. Its a non-issue and a curve ball thrown by the ICE industry that simply claims that EVs dont work in cold weather.
2. Again a comparative statement without the knowledge of what is compaired against. Think of it as washing powder advertisement that compares the performance of some product to "regular washing powder".

The test results show Talga’s anode product significantly outperformed the CAP across a range of charge rates, and achieved very high charge capacity of >300mAh/g at an ultra-fast charge rate of 20C (see Fig 2 for details and Glossary for technical terms).

I love hard numbers and the plots in the associated publication! Super cool! However, this was for Talnode-X, a different product than Talnode-C. Talga, please show an update with the recent Talnode-C Product from the EVA!

I am chasing this question for quite some time now and it seems we will not get the information. It appears that battery component performance is a highly guarded secret among all players. Any measurement depends on the cicrumstances and what it is compared with in the first place as all statements seem to be relative. This is the same for all players that I have seen so far. Its also never disclosed what basis each product is compared against, making it impossible to make relative statements. We simply dont know. I have no idea why this is such a tight regarded trade secret. There are plenty of research papers as well. While I am confident in reading research papers, I am not deep enough in the field of battery material science to interpret everything correctly. @catdog made a very good summary..

Great numbers, do you have a link to the source? In my understanding (unfortunately) something substantial has changed since 2018/2019. Originally, Talnode-C was not coated (i.e. carbon black coated) and now it is coated. That is indicated by the large increase in funding required for the Vittanghi mine and in the DFS text. I absolutely love these numbers as we could see progression over time from Talga and it gives an absolute reference frame. Exactly what we need! However, its a different product if I understand this correctly.

Maybe we dont get specific values because they depend on the customer and the tailored Talnode-C for one customer application. So many factors play a role that its difficult to put everthing in the correct perspective.

However, these numbers are exactly what I am looking for. For test results created by products from the EVA.

I'll have to digest this first. Will take some time as family plus work doesn't leave much room for stuff as deep as this. But I'll look at it :)

I take your point Semmel. It would be nice to have results from the EVA but I just don't think it will happen while they're in final qualification and commercial negotiations.

My main point was that graphite source and characteristics play a very big part in the performance of the anode. Talga's graphite is unique and has been independantly assessed as high grade, highly homogenous, highly conductive and perfectly sized for anode. There plenty of data points which suggests this translates well to battery performance, and I feel Talga know this and are playing their cards very close to their chest.

Anode performance is also highly specific to the requirements of the manufcaturer and dependant on their own manufacturing process, so results are likely commercial in confidence. The best we have for Talga's coated Talnode-C is the Stelvio test done by IV electrics which was part of commercial testing and beat two market anode leaders. The EVA plant is just a scaling up in quantity of the same anode so I'm hopeful the same results should apply to the EVA output. That's as good as it's going to get...and it's enough for me :)

err SYR only company which can produce at volume and the Vidalia plant is supplied by hydro. The US market will still need China supplied AAM anode material for at least the next 20 yrs if not forever. Same goes for Europe. TLG will only be able to produce whenever they are allowed to mine, a fraction of Europe's requirements. It's not a competition. It's complementary to service the explosion in demand. It's all hands on deck to meet demand so they don't have to look for alternatives to graphite and stuff everyone.

The ever increasing use of LFP batteries is going to help because of it's lower battery energy density in the cathode. No point paying higher prices to dope with silicon or use Lithium metal as the anode when natural graphite meets the energy density required.

SYR intend to build a AAM plant in Europe once Vidalia has been expanded to 45kt AAM by 2025 to help meet demand.

Interesting take. Though I don't necessarily agree. Europe's interest is to get independence from china on as much resources as possible. Because they know they might get hosed if china eventually decides to invade Taiwan and trade gets interrupted. It's not gonna happen over night but i expect Europe to do whatever possible to mine Graphite and many other minerals locally, as well as ramp up synthetic production. Also, the power grid is in shambles at least in Europe. It's still working reasonably well but if we lose hydro, nuclear and coal all at once due to heat in the summer, it's gonna get tough. The answer is obviously renewables. There will be enough lobbying power to push fossil fuels wherever possible but it's a losing battle. You can only fight against a tsunami of change for so long. Especially as solar and wind plus batteries becomes cheaper than coal, oil and nuclear even with subsidies (for the fossils and nuclear, not for the renewables). It's not gonna take 20 years.

For Talges success, a lot of capacity is build for the current technology. New battery chemistry might evolve but it's not going to be fast and will not replace the graphite industry, new tech is gonna be added on top. Talges will be producing carbon anode in the order of 2 to 3 mtpa eventually (past 2030). It's going to be sublimented by silicon additives, which reduces the amount of necessary material, making the product cheaper and use less material. Increasing the reach of the ressource. EU will support synthetic anode production as well. We might still import stuff from china and elsewhere due to trade agreements but we will not be dependent on it like we are today.
