About
Adden Energy develops lithium-metal batteries with self-healing solid-state separators, aimed first at fast-charging electric vehicles.
The separators rely on a phenomenon called dynamic stability, which the founding team studied at Harvard for nearly a decade before starting the company. The cells also use a porous lithium metal anode and an improved cathode. Adden says its cells use non-flammable components, and it lists drones, data centers and robotics as other uses.
Adden Energy is based in Waltham, Massachusetts.
