Talga’s graphene silicon product extends capacity of Li-ion battery anode. The solution to effectively higher silicon loadings may be graphene.
“Australian advanced materials technology company, Talga Resources has announced positive initial test results from the development of its graphene silicon lithium-ion anode in the UK.
The results are the first under Talga’s UK Government funded “Safevolt” project – a Talga-led program run in conjunction with consortia partners, Johnson Matthey, the University of Cambridge and manufacturing research group, TWI.
Under Safevolt, Talga is developing a high energy graphene silicon anode product, termed TalnodeTM-Si, targeting significantly higher capacity than commercial graphite anodes.
Talga managing director, Mark Thompson said TalnodeTM-Si will suit the growing demand for Li-ion batteries with higher capacity to extend the range of electric vehicles and work time of portable electronic devices.
“We are excited to see further success as we progress development of our next generation of battery products and materials to be produced from our Swedish resources. We are pleased to be at the fore-front of developing a Li-ion anode product that has a fast growing future, and uses both our emerging supplies of graphene and graphite,” Thompson said.
Major Li-ion battery manufacturers are requiring higher energy density via increasing amounts of silicon in graphite anodes, however silicon use is hindered by a range of battery life and stability problems.”
