Coreshell
Advanced battery solutions company that increases the range of electric vehicles while bringing down costs — so the world can transition to clean energy in time
About Coreshell
Coreshell is a developer of nanolayer coating technology that enables the use of metallurgical silicon in battery anodes. The company's core technology focuses on solving the challenges associated with silicon, which can store significantly more energy than traditional graphite but has historically been too expensive to use in its pure, synthetic form.
By applying a proprietary coating to metallurgical-grade silicon, a lower-cost and more abundant material, Coreshell allows battery manufacturers to increase capacity and performance without incurring high costs. This approach addresses key supply chain issues by utilizing domestically sourced materials. The primary market for this technology is the electric vehicle (EV) and broader battery industry. The company operates on a B2B model, providing its advanced anode materials to battery cell manufacturers. Coreshell has demonstrated its technology in commercial-scale 60 Ah battery cells, indicating a move towards commercialization and large-scale production.
