Coreshell

About

Founded in 2020, Coreshell is a private headquartered in San Leandro, United States with approximately 50-200 employees specializing in Energy Storage.

Coreshell is a battery technology company focused on revolutionizing energy storage through metallurgical silicon anode batteries. The company has developed a breakthrough technology that acts as an artificial SEI (solid electrolyte interphase) and encapsulant, preventing surface degradation and swelling of silicon anodes during charge and discharge cycles. Their comprehensive battery design integrates proprietary technology, binders, active materials, and electrolytes to enable integration of metallurgical silicon anodes at the cell level. Coreshell's solution delivers approximately 30% more range and 25% cost reduction per kWh compared to conventional graphite batteries, while leveraging silicon—the second most abundant element—sourced from existing domestic supply chains producing over 100,000 tons annually. The company targets electric vehicle applications and aims to enable scalable, cost-effective battery production using American-made battery-grade metallurgical silicon.
