The head of battery technology at General Motors revealed that the company may abandon low-cost iron-based battery technology and instead focus on developing lithium-rich manganese batteries (LMR). Previously, General Motors had planned to produce lithium iron phosphate (LFP) batteries at its joint venture factory in Tennessee by the end of 2027 for use in future electric vehicles. However, with the current strategic adjustment, the LFP batteries produced at the factory starting this month will be used for energy storage systems rather than electric vehicles. General Motors has been researching and developing LMR batteries for over a decade. Their cost is comparable to that of LFP batteries produced in the United States, but they offer greater energy storage capacity for the same weight and size. Nevertheless, the large-scale application of LMR technology may be challenging in the short term.
