Solid Power is an industry-leading developer of all solid-state rechargeable batteries for electric vehicles and mobile power markets. Founded in 2012 as a spin-out from the University of Colorado Boulder, Solid Power replaces the flammable liquid electrolyte in a conventional lithium-ion battery with a proprietary sulfide solid electrolyte. As a result, Solid Power’s all solid-state batteries are safer and more stable across a broad temperature range, can provide a 50-100% increase in energy density compared to the best available rechargeable batteries, enable cheaper, more energy-dense battery pack designs and are compatible with traditional lithium-ion manufacturing processes. Solid Power has extensive partnerships with both BMW and Ford to jointly develop all solid-state batteries using the company’s Louisville-based megawatt-hour-scale (MWh) production line. In addition to Volta, Solid Power is backed by prominent investors including Samsung, Hyundai, Ford, and Solvay.
