GM targets 2028 launch of cheaper sodium-ion batteries for large-scale energy storage.

General Motors is shifting focus from electric vehicles to energy storage by developing sodium-ion batteries with startup Peak Energy, aiming for commercialization by 2028. These batteries promise longer life, cheaper use without cooling systems, and U.S.-sourced materials, potentially outperforming current lithium-iron phosphate (LFP) batteries. GM sees strong potential in these batteries for grid storage and bi-directional EV charging to support electricity demand, especially for data centers and utilities. This move follows reduced EV incentives and reflects GM's strategy to monetize battery technology beyond vehicles.
