The 22-layer, 20 Ah cells achieve 330 Wh/kg and are produced on a roll-to-roll battery production line. The company also revealed further details on the 2 Ah cells it delivered to validation partners in October; the products show cycling stability at near room temperature at C/10 discharge rates, with rates up to 3C possible at 70 °C. Solid Power is well-positioned to begin automotive qualification for its batteries in the next two years and anticipates further discharge rate and energy density improvements. While other SSB companies are announcing lab-scale results, Solid Power gains a valuable foothold in the market as one of the only all-SSB startups producing its technology on a pilot line while achieving high energy density cells.
