A spin-out of Brookhaven National labs in 1989 and previously known as Moltech (until 2002), SION POWER is structured around development of a new generation of rechargeable lithium batteries for mobile electronics and electric vehicles. Based on the five times higher energy available from sulfur ions compared to other lithium chemistries, SION POWER's cell offers significant improvements in capacity, operating temperature and discharge rate. Proprietary thin film production techniques and the use of low cost raw materials keep costs no higher than current industry levels. Fairly active in the SBIR arena for several years, two major capital investments (from BASF in 2012 and Cummins in 2021) a recent published article (Dec 2021) indicates that the firm has successfully overcome the issues that dogged historical lithium metal chemistriesâe.g., dendrification, resistive by-productsâby developing a multi-faceted approach to protecting the lithium metal anode. This includes a liquid electrolyte that stabilizes the anode surface; a chemically stable and ionically conductive ceramic polymer barrier for the anode; and proprietary cell compression and an advanced battery management syst
