US startup SiNode Systems has been awarded a $4m grant to develop lithium ion battery technology using silicon and graphene for Ford, Fiat and General Motors.

The grant from the US Advanced Battery Consortium (USABC), a collaborative organization of Fiat Chrysler, Ford Motor Company and General Motors, is for the development of advanced anode materials for automotive lithium-ion battery applications.

The 30-month program will focus on the development of silicon-graphene high-energy anode material for vehicle applications and the development and scale up of pouch cells with higher battery capacity and faster charging rates than today’s graphite-based lithium ion pouches with a capacity of 372 mAh/g. Instead, the graphene approach can provide capacities between 1000 mAh/g and 2500 mAh/g, while the nano-engineered porosity introduced into the graphene layers allows rapid diffusion of lithium through the structure for faster charging.

All of this can be produced with a low cost, chemistry-based manufacturing process, says the Chicago-based company. “SiNode Systems is pleased to be a recipient of this grant and is proud to contribute to USABC’s battery technology research and development programs,” said Samir Mayekar, Co-Founder and CEO of SiNode Systems. “We believe our advanced anode materials technology will be an enabler in improving the performance and reducing the cost of advanced batteries for vehicle electrification.”
