GM’s Battery Plans: Why the Shift Away From LFP Might Make Sense

General Motors once planned to use lithium-iron phosphate (LFP) batteries in some of its future electric vehicles. LFP batteries are cheaper and last longer, which makes them great for budget-friendly cars. But now, the company seems to be changing its mind. Instead of focusing on LFP, GM is betting more on lithium manganese-rich (LMR) batteries, which pack more energy into the same space without costing much more to produce in the U. S.Even though GM still plans to make LFP batteries—just not for cars—its decision to move away from them could surprise rivals. Many automakers, especially in China, love LFP because it’s affordable and reliable. But GM thinks LMR could be the better long-term choice. The company even calls LMR its "workhorse" and says it will be the main battery type for most of its future electric models. Still, GM hasn’t completely ruled out LFP yet—it might still have a place somewhere else. This shift shows how fast battery technology is changing. Cheaper doesn’t always mean better, especially when energy storage matters more than cost. GM’s move could also reflect concerns about supply chains. Right now, most LFP batteries come from China, and U. S. automakers want to rely less on foreign suppliers. LMR batteries, on the other hand, can be made in America, which fits GM’s push for more local production.
