- General Motors said it's developing sodium ion batteries for grid-scale energy storage systems.
- Chinese battery makers have already commercialized the technology. Now multiple U.S. companies are betting on it, too.
- Sodium-ion batteries have plenty of advantages over current lithium-based chemistries.
General Motors is teaming up with U.S. startup Peak Energy to deploy sodium-ion batteries for energy storage systems, the automaker announced on Tuesday. As electric vehicle sales remain uneven, U.S. automakers are redirecting their battery ambitions toward the booming energy storage market, where demand is surging on the back of power-hungry AI data centers.
