GM’s new ‘manganese-rich’ battery promises cheaper EVs in 2028
Lithium-manganese-rich (LMR) batteries should slash costs without sacrificing much range.
LMR will also dramatically reduce the amount of nickel and cobalt compared with GM’s most advanced cells, two critical minerals that aren’t readily available from domestic sources in the United States. Andy Oury, business planning manager at GM, said that LMR could “take up a huge chunk in the middle” of the market, pushing LFP to entry level vehicles and pricey NMC to applications that need long range and high energy density. Its efforts kicked into high gear in the last couple years as engineers successfully produced large-format cells similar to those in EVs on the road today.
