Solid Power

Solid Power advances solid-state EV batteries with BMW and Ford backing, raising $130M to date. Its sulfide-based electrolyte design offers 50% higher energy density than today's lithium-ion standard, targeting 500 Wh/L by 2026. While quantumScape leads in charging speed, Solid Power claims a cost advantage of 20% less per kWh compared to the industry average for solid-state prototypes. The company has shipped 15,000+ prototype cells for third-party testing, validating thermal stability and 1,000-cycle longevity at the pack level.
