G.M. Plans to Develop Energy Storage Batteries as E.V. Sales Flag

General Motors plans to begin making components for large storage batteries, the company said Tuesday, joining Tesla, Ford Motor and other carmakers in pushing into a growing market and compensating for slower sales of electric vehicles in the United States.

The batteries, which can be the size of shipping containers, store excess energy from solar panels, wind turbines and other power sources. Utilities, data centers and other big energy consumers use them for backup power or to manage fluctuations in electricity supply or demand.

Tesla has been selling storage batteries since 2015. Ford said last year that it would convert a factory in Kentucky to make large batteries, after shutting down production of electric vehicle batteries at the plant because car sales fell short of expectations.

G.M. plans to develop battery cells for large-scale storage using a relatively new technology. Peak Energy, a company based in California and Colorado that is teaming up with the automaker, will integrate the cells into industrial-scale systems.
