GM Develops Sodium-Ion Battery for Data Center Storage
General Motors is developing a sodium-ion battery with Peak Energy for large-scale energy storage, targeting commercialization by 2028. The company has also announced plans for a lithium manganese-rich battery for pickups and SUVs by the same year.
forbes.comGeneral Motors announced plans to develop a sodium-ion battery for large-scale energy storage in partnership with startup Peak Energy. The company aims to commercialize the cells by 2028. The sodium-ion chemistry is designed to operate without active cooling systems and to function at temperatures up to 55 degrees Celsius.
Company executives said the cells have a projected 20-year usable life and use materials that can be sourced domestically.
GM is also developing a lithium manganese-rich battery for large pickups and SUVs, with production targeted for 2028. Large-scale production of the sodium-ion cells is not expected for at least two years.
GM has a program with California utility PG&E to test vehicle-to-grid power flow. The utility offers a $4,500 rebate to GM electric vehicle owners who install smart charging equipment. Executives said the bidirectional capability could allow utilities to draw power from vehicle batteries during peak demand periods.
