GM's new ‘manganese rich' battery promises cheaper EVs in 2028
1. GM unveiled lithium-manganese-rich (LMR) batteries to reduce costs and extend range. 2. The LMR chemistry could achieve over 400 miles of range compared to existing batteries. 3. Reduced reliance on nickel and cobalt supports domestic sourcing goals for the supply chain. 4. LMR could dominate the mid-market, shifting LFP to budget vehicles and NMC to high-end. 5. GM aims to scale LMR production by 2028, supported by joint ventures and patents.
