An entirely new battery concept.


Solid Power is an industry-leading developer of the next-generation of all solid-state rechargeable batteries. Possessing no volatile or flammable liquid components, our solid-state batteries are extremely energy dense while also possessing ultimate safety and reliability. Together, these performance attributes can enable profound performance improvements of battery-powered devices such as portable electronics, electric vehicles, aircraft and satellites through increased run time, increased safety and lower cost.

Established in 2012 as a spin-out company from the University of Colorado Boulder based on ground-breaking research in solid-state battery technology, Solid Power has assembled a world-class team of battery researchers and engineers with the exclusive goal of commercializing the company’s next-generation solid-state rechargeable batteries. We occupy a state-of-the-art, 7,000 square-foot facility located within the Colorado Technology Center in Louisville, CO along the beautiful front range of the Rocky Mountains. Our facility has full capabilities spanning new material synthesis, small-volume pilot-scale material and cell production and prototype device assembly and characterization.


Our technology is based on combining an exceptionally high capacity cathode with a high capacity lithium metal anode and in combination with a high ionic conductivity solid separator. Our battery materials are 100-pecent inorganic and possess no flammable or volatile components. Our batteries provide substantially higher energy than conventional lithium ion (2-3X greater) while also enabling lower cost systems due to the potential for eliminating many of the costly safety features typically associated with lithium-ion systems.


Exceptionally energy dense materials enabling a considerably longer run-time per charge than existing batteries.


No volatile or flammable materials thereby enabling ultimate safety.


Exceptionally stable materials possessing unsurpassed shelf life and high temperature stability.

Solid State

Unique performance attributes achievable only in the solid-state phase.
