European battery and advanced materials supply chain company Talga Group (ASX:TLG) reports following positive customer tests and feedback, it is planning to produce greater quantities of its Talnode-Si for commercial qualification at a pilot plant in Germany.
The company says Talnode-Si is a silicon anode product for lithium-ion batteries that is a composite of graphite, graphene and around 50% silicon. Talnode-Si is designed to ‘significantly’ boost battery energy capacity when blended into existing commercial graphite anode materials.
Talga has been developing Talnode-Si since 2018 at its facilities in Cambridge, UK with commercial samples being produced at its pilot facility in Rudolstadt in Germany.
Recent qualification and pilot trials completed with a global electric vehicle (EV) manufacturer confirmed Talnode-Si’s performance under commercial cell manufacturing conditions, with lithium-ion batteries containing 9% Talnode-Si boosting battery energy capacity by around 40%. Test results of first-cycle efficiency and 500 cycle life to date also exceeded customer targets at this stage of development.
Talga Managing Director Mark Thompson says: “We are very pleased with the rapid advancements across Talnode-Si customer qualifications and scale-up.
“The commercialisation of our silicon-graphene composite will complement our flagship Talnode-C graphite anode product to diversify Talga’s business growth”

Talga reports commissioning of the expanded pilot line is to be completed in the first quarter of 2023. In parallel, the company is also conducting feasibility work towards accelerating commercial Talnode-Si production options.

Negotiations with leading global EV manufacturers regarding supply volumes have commenced, and production site selection in Europe is also well underway.
Talga is a European battery and advanced materials supply chain company focusing on offering products critical to innovation. The company holds the Vittangi Graphite Project located in northern Sweden.
Graphite from this project is used in the production of the Talnode-C, Talnode-Si and Talnode-E lithium-ion battery anodes, which in turn is used in batteries for EVs, consumer electronics and energy storage systems.
