GM’s new ‘manganese rich’ battery promises cheaper EVs in 2028
General Motors announced a new lithium-manganese-rich (LMR) battery that aims to reduce EV costs and maintain long driving ranges, targeting over 400 miles. This new chemistry reduces dependence on cobalt and nickel, relying instead on cheaper manganese. The LMR batteries may significantly change the EV market by 2028, as GM plans to produce them with fewer parts while maintaining performance metrics.
Key points
- GM introduces LMR battery chemistry to reduce costs and improve range.
- LMR batteries promise over 400 miles range and less reliance on cobalt and nickel.
- Cheaper manganese is used, with compositions featuring 0-2% cobalt, 30-40% nickel, and 60-70% manganese.
- Transitioning to prismatic cells from pouches will reduce parts by over 50%.
- LMR may dominate mid-market EVs, complementing cheaper LFP and high-end NMC batteries.
- Production and research invested by GM and LG Energy Solution may yield significant future advancements.
Why it matters
- The move aligns with global trends focusing on sustainable and economically viable EV solutions by 2025.
- Increased interest in battery technologies that reduce reliance on scarce minerals mirrors industry shifts towards localized sourcing.
- The push for cost-effective EVs reflects broader market pressures to enhance accessibility for consumers amid rising EV adoption rates.
GM's LMR battery technology could revolutionize the EV market by 2028, providing an affordable option with impressive range, indicative of the industry's shift towards sustainability and local supply chains.
