KATHMANDU: General Motors (GM) and LG Energy Solution have joined hands to develop next-generation electric vehicle (EV) batteries, offering longer range, lower costs and enhanced safety. The companies aim to begin commercial production of these lithium manganese-rich (LMR) batteries in the US by 2028.
According to GM, these LMR batteries are expected to provide up to 643 km of range on a single charge. These batteries will be used in electric trucks and SUVs, making them ideal for long-distance travel, the company added. Existing Chevrolet and Cadillac electric models of GM use high-nickel batteries and offer a range of about 483 to 515 km.
The collaboration is part of a broader effort to make EVs more affordable and sustainable. Unlike traditional EV batteries, which rely heavily on expensive and ethically controversial materials like cobalt, LMR batteries use more manganese, which is both cheaper and more widely available. This makes the new battery technology cost-effective and eco-friendly.
GM, the legacy US carmaker, has been working on manganese-rich battery technology since 2015.
GM has developed approximately 300 full-size LMR battery cell prototypes and is optimistic about their performance. These batteries are designed with a prismatic shape, which improves space efficiency and contributes to the extended range. Pilot production of the new battery cells is expected to begin in late 2027 through Ultium Cells, a joint venture between GM and LG.
According to news reports, the final design will be validated at GM’s Wallace Battery Cell Innovation Center in Michigan and LG Energy Solution’s new facility, set to open in early 2027.
While LMR battery technology holds great promise, it faces challenges, including capacity loss and reduced thermal stability, say experts. However, GM engineers are confident that innovative manufacturing techniques can address these issues.
GM, the legacy US carmaker, has been working on manganese-rich battery technology since 2015. With this new battery, the company believes it will gain a competitive edge in the EV market, both in performance and price.
