Talga Group has provided an update on commercialization and customer qualification of Talnode®-Si, the Company’s proprietary silicon anode product for lithium-ion (Li-ion) batteries. Talnode®-Si is a composite of graphite, graphene and ~50% silicon 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, Germany.
Recent qualification and pilot trials completed with a global EV manufacturer reportedly confirmed Talnode®-Si performance under commercial cell manufacturing conditions. Li-ion battery cells containing 9% Talnode®-Si, manufactured in battery tolling and in-house development facilities, boosted battery
energy capacity by ~40%.
Test results of first cycle efficiency and 500 cycle life to date exceed customer targets at this stage of development.
Following positive customer tests and feedback, in accordance with its commercial strategy, Talga is
expanding its existing pilot line in Rudolstadt, Germany, to produce greater quantities of Talnode®-Si
for commercial qualification.
Commissioning of the expanded pilot line is to be completed in Q1 2023.
In parallel, the Company is conducting feasibility work towards accelerating commercial Talnode®-Si
production options. Negotiations with leading global EV manufacturers regarding supply volumes has
commenced and production site location selection in Europe is well underway.
