SAN FRANCISCO, June 10 : General Motors may scrap plans to use a lower-cost, iron-based battery chemistry that many automakers are using to cut electric-vehicle costs, GM's head of battery technology said. The Detroit automaker had said it planned to develop lithium-iron phosphate, or LFP, batteries for use

After LFP and LMR, the automaker is betting on yet another battery chemistry type.

General Motors (GM) has partnered with sodium-ion battery storage startup Peak Energy to target the grid-scale energy storage market.

General Motors may stop using LFP batteries in future EVs, redirecting its Tennessee plant toward energy storage systems after a $70 million retooling

GM and Peak Energy are developing sodium-ion batteries that they say can cut grid storage costs by 20% and boost uptime.

General Motors is considering using an unproven, but possibly more powerful, battery technology for its electric vehicles. The stock is up.

LFP is the industry’s go-to cheap EV battery tech, but GM says another chemistry, LMR, could offer similar cost benefits with fewer drawbacks.
