Coreshell Technologies Inc
About
Coreshell makes lithium-ion battery cells whose anodes use US-produced metallurgical silicon in place of graphite.
Its patented coating acts as an artificial SEI and an encapsulant, keeping the silicon from swelling and breaking down during cycling. The company says the cells run on existing battery manufacturing equipment without retooling, and it sources its silicon through a long-term partnership with Ferroglobe. Coreshell pitches its cells for electric vehicles, drones and defense as free of Chinese critical minerals.
Coreshell Technologies is based in San Leandro, California. The company says it won a $50 million US Department of Energy grant to build a gigafactory.
