Summary
General Motors (GM) is partnering with Peak Energy to enter the grid-scale energy storage market, focusing on sodium-ion battery technology. Peak Energy, founded in 2023, delivered the first grid-scale sodium-ion storage solution to the US electric grid in 2025 and plans to begin production at a domestic giga-scale sodium-ion battery facility early next year. GM argues sodium-ion technology offers lower costs and improved safety compared to traditional lithium-ion batteries, as both GM and its rivals pivot from failed EV developments toward stationary storage.
