General Motors is moving to lock down domestic battery supply for its next wave of electric vehicles and energy storage systems, a shift that could help insulate the automaker from Washington’s escalating scrutiny of China-linked auto technology. The strategy matters because batteries sit at the center of GM’s EV margins, energy-storage ambitions and future manufacturing footprint, and a more U.S.-centric supply chain could reduce tariff, policy and logistics risk.
GM Works With Peak Energy on Domestic Batteries
GM said it is working with Denver-based Peak Energy on sodium-ion battery cells for energy storage systems and plans to prioritize domestic cell production for upcoming EVs. Vice President of battery and sustainability Kurt Kelty said the company aims to have a supply chain that is “domestic” within two to three years, with the new cells potentially deployed as soon as 2029.
The push comes days after the Trump administration criticized Ford for relying on Chinese battery maker CATL, underscoring how quickly battery sourcing has become a political as well as industrial issue. For GM, the optics matter nearly as much as the chemistry: a local supply chain reduces exposure to China for inputs such as lithium and ferrous sulfate, while tapping U.S.-available materials like sodium derived from soda ash.
That could have real financial implications. GM has already told investors it expects to spend about $10 billion to $12 billion this year on capital spending and battery-cell joint ventures, so any move that lowers imported-content risk or smooths sourcing could support margins over time. Sodium-ion batteries are not yet mass-market, but GM is betting the technology can help it leapfrog some Chinese battery advances and build a cheaper, more domestically anchored energy-storage business.
Investors will also read the move as part of a broader reset in U.S. auto strategy, where supply-chain security is becoming as important as EV range and charging speed. GM’s shares have held above both the 50-day and 200-day moving averages in recent trading, suggesting the market is still rewarding execution and resilience even as policy risk swirls around the sector.
The key question now is whether GM can turn the sourcing strategy into an actual cost advantage before 2029, when these cells could begin rolling out. Any setbacks in scaling sodium-ion production, or a broader escalation in U.S.-China trade tensions, would keep pressure on automakers to localize faster.
