GM Teams With Peak Energy on Grid Batteries After Ford's Move

GM will develop sodium-ion cells with Peak Energy, sell LFP batteries to LG Energy Solution and buy a 7.2 megawatt-hour Redwood system that could save $3 million.

  • On Tuesday, General Motors announced a partnership with startup Peak Energy to develop sodium-ion battery cells for grid-scale energy storage, with plans to reach trial production by 2028.
  • Mounting energy costs and surging data center demand prompted the strategy, as GM seeks to monetize battery manufacturing capacity that currently serves only its vehicle business.
  • Alongside the Peak Energy collaboration, GM is expanding work with Redwood Materials to redeploy 10,000 used EV batteries and supplying lithium-iron-phosphate cells to LG Energy Solution for grid projects.
  • Sodium-Ion batteries offer users a cheaper, more robust solution because they require no active cooling and operate across broader temperature ranges, reducing system complexity and maintenance costs.
  • By betting on multiple battery chemistries including LMR and sodium-ion, GM aims to remain resilient regardless of EV sales fluctuations, establishing energy storage as a critical long-term revenue stream.
