Solid Power

Solid Power will develop a 3D-structured lithium (Li) metal anode and novel sulfur (S) composite cathode to enable high-energy and fast-charging electric vehicle battery cells. Solid Power’s advanced solid-state electrolyte will enable a three-dimensional Li metal anode and S cathode while overcoming the primary challenges for conventional lithium-sulfur chemistry. Solid Power has also developed roll-to-roll processes for Li metal all-solid-state battery (ASSB) cell fabrication, which can be readily deployed to support this project. These combined innovations will lead to a safe, high-energy density (≥ 500 Watt-hour (Wh)/kg), fast-charging, low-temperature performing, and low-cost ASSB cell.
