Talga Resources announced test results from Li-ion battery anode product, Talnode-Si

Australian advanced materials technology company, Talga Resources Ltd (ASX:TLG) has announced additional test results from its high energy graphene silicon lithium-ion (Li-ion) battery anode product - Talnode-Si.

On 24 October 2018, TLG notified that it had received optimistic test results from Talga graphene in Li-ion battery silicon anode which reflected ~50% elevated anode capacity over commercial graphite reference, as a result of which the battery life would rise for portable and EV markets. The company also said that the progress on the other UK based Faraday challenge projects, “Scale-up” and “Sodium” were in the continuation and according to plan.Â

Highlights of new half- cell cycling test results include:

• ~70% higher reversible capacity (~600mAh/g) than commercial graphite (~350mAh/g)
• Coulombic efficiency of 99.5% - 99.9% with first cycle efficiency ~ 91%
• Up to 94% reversible capacity (after >130 cycles in a range of silicon loadings)

Managing Director, Mr Mark Thompson said that the rapid development of the company’s natural graphite anode products for Li-ion batteries had been extraordinary and the continued positive market response to products under development, Talnode-Si and Talnode-X, as well as its flagship product, Talnode-C, support plans for scaling up of Talnode products as part of its vertically integrated business strategy.

Talnode-Si consists of a mixture of silicon and graphene particles engineered by Talga, to be suitable for existing Li-ion battery manufacturing equipment as a high performance, cost-effective and scalable replacement for standard graphite anode materials. Commercial samples are being prepared, under confidentiality and material transfer agreements, with delivery commencing end of February 2019. Recipients include some of the world’s largest electronics companies.

Development is going on under the Safevolt project, a part of the £246 million UK-funded Faraday program, with Talga partners Johnson Matthey, Cambridge University and TWI. Based on the encouraging test results to date, the Company had opted to progress to full cell testing and optimisation of Talnode-Si.

On 31 January 2019, TLG published its quarterly activities and cash flow results ending 31 December 2018. During the quarter, battery anode initial testing delivered outstanding performance results from the range of trademarked Lithium-ion battery products.  Talphene-enhanced lightweight epoxy composites showed high conductivity test results for lightning strike protection and anti-icing in aircraft and wind turbine applications. The letter of intent was signed subsequent to the period with global carbon and technology giant,Schunk Group, to explore the incorporation of Talphene into an automotive application. Activities at the Company’s four north Sweden cobalt-copper-gold projects recommenced with encouraging results reported and resource drilling and on-going exploration planned.

Managing Director, Mark Thompson said that the December quarter capped a year of intense engagement with an expansion of the Company’s alliances, growing portfolio of commercial agreements and R&D initiatives with major European, UK and global conglomerates.

Talga closed out the 2018 December quarter with A$13.8 million cash-in-bank. Following the expiry of listed options in December, the Company in January had 218,192,650 quoted ordinary shares on issue and at the close of the ASX on 30 January 2019, was capitalised at A$75.3 million.

By the end of the trading session on 19 February 2019, the stock of the company stood at A$0.410, up by 9.333% or 0.035 points. The company has a market capitalization of circa A$81.82 million and 218.19 million shares outstanding.
