The cells exhibit improved room-temperature operation and discharge rates up to 5C, and Solid Power will deliver several hundred cells to partners by the end of 2020. The company was producing 2 Ah batteries last year on its pilot roll-to-roll production line but has since improved battery performance. In particular, the 5C discharge rate was increased from 1C last year, though Solid Power did not disclose effects on efficiency or rate capability. Solid-state batteries (SSBs) are typically limited by slower charge/discharge rates, but lithium metal anodes can enable higher rates. Solid Power leads in SSB production, having successfully completed roll-to-roll production and cell stacking, a feat that competitors continue to struggle with.
