GM explores new battery chemistry to power AI data centers, energy storage

• GM is partnering with Denver-based Peak Energy to develop sodium-ion battery cells for customer use after 2028, targeting lower costs and less system complexity than lithium-ion batteries
• The automaker is expanding vehicle-to-grid services through utility partnerships in California and Michigan, allowing EV owners to sell power back to the grid during peak hours
• Residential electricity prices in the U.S. have risen from 12.76 cents per kilowatt-hour in January 2020 to 18.83 cents in March 2026, with further increases expected to 19 cents by March 2027

Summary: GM Explores Sodium-Ion Batteries for AI Data Centers and Energy Storage

Key Developments:

General Motors is expanding beyond electric vehicles to capitalize on surging demand for energy storage and AI data center infrastructure. The automaker announced plans to develop next-generation sodium-ion batteries specifically for grid-scale energy storage, partnering with Denver-based Peak Energy to produce commercial cells after 2028.

Battery Technology Focus:

Sodium-ion batteries offer significant advantages over traditional lithium-ion technology, including operation without active cooling, reduced system complexity, wider temperature ranges, and lower upfront and operating costs. GM's battery VP Kurt Kelty stated these systems "will reshape grid-scale energy storage" and could eventually outperform lithium iron phosphate (LFP) batteries.

Additional Initiatives:

• Expanding vehicle-to-grid capabilities allowing EV owners to sell power back to utilities during peak hours
• Partnerships with utility companies in California and Michigan, with nationwide expansion planned
• New "Energy Pass" for seamless public charging
• Continued LFP battery production through joint ventures
• Battery recycling programs with Redwood Materials

Market Context:

The move addresses rising energy costs and anticipated massive infrastructure spending for AI data centers. U.S. residential electricity prices have surged 48% since January 2020, reaching 18.83 cents per kilowatt-hour in March 2026, with further increases expected.

Current Capacity:

GM's Ultium Cells joint venture operates 90 gigawatt-hours of production capacity across Ohio and Tennessee facilities, with a recent $70 million investment for LFP battery production at the Tennessee plant.

The strategy positions GM to compete in the growing energy storage market while leveraging existing battery manufacturing expertise beyond automotive applications.
