- GM is positioning LMR batteries as the core technology for future EV growth.
- LFP batteries may remain limited to energy storage and select EV models.
General Motors is reassessing its earlier plans for lithium-iron phosphate (LFP) batteries as the automaker increasingly focuses on lithium-manganese-rich (LMR) battery technology for future electric vehicles. According to company executives, LMR chemistry has emerged as a key pillar of GM’s long-term EV roadmap because it offers competitive production costs while delivering greater energy density. This strategic shift indicates that GM may significantly reduce the role of LFP batteries in its future vehicle lineup, even though the company had previously announced investments to expand LFP manufacturing capabilities.
LMR Batteries Become Central to GM's EV Roadmap
Kurt Kelty, Vice President of Battery & Sustainability at GM, described LMR batteries as the “workhorse” of the company’s electric vehicle strategy. The technology is designed to provide energy storage levels exceeding those of LFP batteries while maintaining comparable manufacturing costs in the U.S. market. By storing more energy within the same size and weight constraints, LMR batteries could enable longer driving ranges and improved vehicle performance. This combination of cost efficiency and higher energy density makes LMR chemistry increasingly attractive for large electric vehicles, including trucks and SUVs.
Limited Role for LFP Batteries in Future Applications
Although GM had previously announced plans to produce LFP batteries domestically, their role now appears more specialized. United States-based Ultium Cells revealed a USD 70 million investment in March to begin manufacturing LFP batteries at Spring Hill, Tennessee. However, these batteries are expected to support energy storage systems rather than broad deployment across GM’s EV portfolio. Currently, the revived Chevrolet Bolt remains the only GM electric vehicle in the U.S. utilizing LFP batteries, with cells supplied by CATL.
GM and LG Energy Solution Advance LMR Commercialization
In May 2025, LG Energy Solution and GM announced plans to commercialize LMR battery cells using a prismatic form factor tailored for future electric trucks and full-size SUVs. Through Ultium Cells, their battery joint venture, the companies aim to become the first automotive manufacturer to deploy LMR prismatic batteries in electric vehicles. Commercial production of these advanced cells in the U.S. is targeted for 2028, reinforcing the company’s commitment to developing next-generation battery technologies for large-scale EV adoption.

| LFP Production | Primarily for energy storage systems |
| Commercial Launch | LMR production targeted for 2028 |
| Current LFP EV | Chevrolet Bolt in the U.S. |
Industry Implications for EV Battery Development
GM’s strategic emphasis on LMR technology highlights the growing competition among battery chemistries as automakers seek optimal combinations of cost, performance, and supply chain resilience. While LFP batteries remain valued for affordability and safety, LMR chemistry could offer a balance between energy density and manufacturing economics for larger electric vehicles. As battery innovation accelerates, the success of GM’s LMR commercialization efforts may influence future industry investment patterns and reshape battery selection strategies across the automotive sector.
Frequently Asked Questions
Why is GM prioritizing LMR batteries over LFP batteries?
GM is prioritizing LMR batteries because they can provide higher energy density while maintaining production costs similar to LFP batteries in the U.S. This enables automakers to deliver longer driving ranges without significantly increasing manufacturing expenses. According to company executives, LMR chemistry is expected to support future electric trucks and SUVs more effectively. The technology also aligns with GM’s long-term electrification roadmap and could help improve vehicle performance while maintaining competitive pricing in the rapidly evolving EV market.
What role will LFP batteries play in GM’s future strategy?
LFP batteries are expected to remain part of GM’s portfolio but with more limited applications than previously envisioned. Current plans indicate that domestically produced LFP cells may primarily serve energy storage systems rather than widespread EV deployment. The Chevrolet Bolt currently remains the only GM EV in the U.S. using LFP batteries supplied by CATL. As GM advances LMR commercialization, LFP technology may continue supporting specialized applications where cost efficiency and durability are prioritized over maximum energy density.
