Solid Power, Inc. is a developer of all-solid-state rechargeable battery technology designed to improve energy density, safety and lifecycle performance for electric vehicles, aerospace and defense applications. The company’s proprietary solid electrolyte materials replace the flammable liquid electrolytes used in conventional lithium-ion batteries, enabling cells with higher energy density, improved thermal stability and reduced risk of fire or explosion.
Founded in 2012 as a spin-off from the University of Colorado Boulder, Solid Power is headquartered in Louisville, Colorado. The company has attracted strategic partnerships and development agreements with leading automotive manufacturers, including Ford Motor Company and BMW Group, to advance solid-state cell prototypes and scale toward pilot production. Solid Power also collaborates with specialty materials suppliers and contract manufacturers to refine cell architectures and assembly processes.
Solid Power’s core technology centers on sulfide-based solid electrolytes that support lithium metal anodes, delivering theoretical energy densities in excess of 400 Wh/kg. The company operates a pilot production line in Colorado and is working to demonstrate automotive-grade cells that meet industry requirements for durability, charge rate and operating temperature range. Its roadmap envisions transitioning from gram-scale prototypes to multi-kilogram battery modules suitable for electric vehicle integration.
Led by President and Chief Executive Officer Douglas W. Campbell, Solid Power continues to expand its engineering team and engage with OEM and supply-chain collaborators across North America and Europe. With funding from institutional and strategic investors, the company is focused on advancing solid-state batteries from laboratory validation to commercial readiness over the coming years.
