Hi. Question: In the Feasibility Study Results for Vittangi Project, the capital cost are 29.3 AUSD$m. It's almost nothing for many business, and very, very low for a mining project. What are they waiting for??? Thanks.
TLGRF - TALGA BREAKTHROUGH IN LI-ION BATTERY PERFORMANCE
Advanced material technology company, Perth-based Talga Resources Ltd
(“Talga” or “the Company”) (ASX:TLG), is pleased to announce it has
achieved a significant breakthrough in the performance of its graphite anode
material in commercial-size cells for the lithium-ion (“Li-ion”) battery market.
In tests at leading global independent facility WMG, part of the University of
Warwick’s Energy Innovation Centre, Talga’s graphite anode material was
benchmarked against a current market leading anode graphite product.
A summary of the battery test results is appended below in the Technical
Summary section. Highlights are as follows:
Test Results - Performance benefits over reference anode graphite
• 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
Cost and other efficiencies over current commercial anode graphite
• No micronisation
• No spheronisation
• No milling losses (high yield)
• No coating
• Potentially less waste, energy and environmental impacts
Benefits for Talga
• Can use as a by-product of graphene production
• European Li-ion battery market growing at CAGR 24% 2020-2025
• Increased near term sales potential in addition to graphene products
• Positions Talga to enter market at higher level of Li-ion anode supply
chain and higher price point
• Results show potential to exceed synthetic and natural graphite
standards used by global battery component supply

Talga Managing Director, Mr Mark Thompson:
“These results are a highly significant development for Talga. The unique characteristics of our
Swedish graphite ore body combined with our proprietary processing technologies produces a Li-ion
battery with significantly higher power and energy as tested by WMG.
The Company considers that based on the results, Talga’s graphite will set the industry standard for
lowering cost of production as it eliminates comparatively expensive industry standard spheronisation/
micronisation and coating required for material currently sourced from Chinese and other graphite
flake producers. We also don’t see their large milling losses resulting from milling down large graphite
flakes to suit battery anode size material.
The test results and Talga’s unique position in the market create optionality for scale-up development,
commercial partnerships and sales of advanced materials in addition to graphene-only products in
future.
Talga’s significant resources positions our energy products division to evolve into a stand-alone battery
technology company with exclusive access to a lower cost and unique, high performance battery
grade graphite, sourced from our wholly owned deposits in Sweden.”
TECHNICAL SUMMARY
Test Battery Cell Production
A range of Li-ion battery pouch cells were fabricated using Talga’s graphite anode and commercial
nickel manganese cobalt (“NMC”) cathode at the battery prototyping facility at the Warwick
Manufacturing Group (“WMG”) in the UK (Fig 1). Standard industrial roll to roll processing conditions
were followed to prepare large format (A5) pouch cells that are currently used in commercial EV
battery packs, e.g Nissan Leaf and BMW i3 (Fig 2).
The procedure to make the battery cells starts with the formulation of the active material slurries with
optimised rheology to coat anode and cathode electrodes on copper and aluminium rolls respectively.
The coated electrodes are then calendered to attain higher electrode densities and required porosity.
This is followed by cutting the electrodes to the required size and stacking with a separator
sandwiched between the electrodes to form an A5 size pouch cell which is then filled with a standard
lithium salt electrolyte (LiPF6) dissolved in a carbonate solvent.
A commercial reference graphite anode was prepared at the same time and under the same conditions
to the Talga material. Both Talga’s electrodes and the commercial reference electrodes had identical
weight inside the cells and paired with the same type of NMC cathode.

Battery Tests and Results
Following assembly, tests of the cells formation process and the charge-discharge cycle were
performed under identical conditions for all the reference commercial graphite anode based NMC cells
and the Talga anode based NMC cells.
Measurements of the pouch cell performance at WMG show significantly reduced cell resistance for
the Talga anode, with higher capacity and better power characteristics compared to the commercial
anode graphite benchmarked in this work. 20% higher capacity is observed for identical active
material content at 0.5C and 2C rates respectively for cells with Talga’s anode (Fig 3), and the first
cycle loss in the full cell is lower at 6%. Talga battery cells demonstrate superior rate capability at
faster charge-discharge rates up to 2C (Fig 4).
Voltage charging profiles at the higher 2C rate perform much better with the Talga anode compared to
the reference graphite and is extremely stable, retaining more than 99% of their initial capacity under
accelerated tests to 300 cycles. The cycling stability compares well to the best commercial cells
available in the market today and indicates normal life of greater than 4,000 cycles (Fig 5).

Figure 3 (left) Talga full capacity at 0.5C: 5.63 Ah, capacity retention at 68 cycles: 100% (5.63Ah). Reference
graphite at 0.5C: 4.02Ah full capacity and 3.90Ah at 68 cycles, capacity retention: 97.0%.
(right) Talga full capacity at 2C: 4.57Ah, capacity retention at 108 cycles: 100% (4.57Ah). Reference graphite full
capacity at 2C: 3.83Ah, capacity retention at 108 cycles: 95.8% (3.67Ah).

Conclusions and Next Steps
The results show potential for Talga graphite anodes to exceed synthetic and natural graphite
standards used by the global battery component supply, with higher performance, energy, power and
life span at potentially lower cost and no decrease in safety (Fig 6). Additionally the results open up
potential for Talga to enter the Li-ion battery anode supply chain at a much higher level (and higher
price point).
With Talga’s large and high grade graphite resources, in house technical team, unique product and
cost profile there is clear potential for near term sales in addition to graphene products, particularly in
Europe where the Li-ion battery market is growing rapidly (CAGR 24% for 2020-2025*). Talks are
underway with major European and Asian based battery manufacturers and end users.

No question. Such a great diversity of applications.
If we can develop a solid graphene business we should be golden.
