Sion Power will supply batteries using its metallic lithium anode battery technology to Cummins for commercial vehicles. Lithium anodes offer much higher energy densities than incumbent anodes, but poor cycle life, safety, and limited production capacity remain large barriers to commercial adoption. Despite the technical hurdles for widespread adoption, Cummins' use of Sion Power's technology will provide the company an early market opportunity in applications where payload is a concern. Clients should note that the partnership highlights how companies interested in electrification can incorporate new technology without waiting for commercial-scale production.
