US car maker joins battery energy storage system (BESS) market with lithium-ion products expected to enter production imminently through LG partnership. Announces sodium-ion R&D program and plan to ramp up bidirectional capability for GM vehicles. The move follows Ford Motor Company’s decision to repurpose EV manufacturing capacity to build a BESS unit unveiled earlier in 2026.

The carmaker scaled back electric vehicle plans, but is going all in on advanced batteries, including a new sodium-ion chemistry designed for large-scale power storage.

GM partnered with Peak Energy on sodium-ion batteries and expanded its Redwood Materials deal to supply energy storage for data centres and the grid.
