Coreshell (Coreshell Technologies, Inc.) is a San Leandro, California battery technology company founded in 2017 that develops silicon-anode lithium-ion battery cells built on low-cost, domestically sourced metallurgical-grade silicon instead of graphite or refined polysilicon. A proprietary nanolayer surface coating stabilizes the silicon anode, and the company has unveiled commercial-scale 60 Ah cells aimed at electric vehicles, defense platforms and stationary energy storage. Coreshell is a materials and cell manufacturer, not a software vendor: its public web presence is a Webflow marketing site with no developer portal, API reference, machine-readable specification, SDK, or public code repository.
