General Motors has unveiled a new battery chemistry called lithium-manganese-rich (LMR), which aims to cut costs while delivering a driving range close to the most advanced batteries available. According to Kurt Kelty, GM's VP of battery, the new technology allows for over 400 miles of range in trucks while using significantly less nickel and cobalt, reducing dependence on these scarce minerals. GM's previous batteries required more costly materials, whereas the LMR cells will maximize the use of manganese for a more cost-effective solution and lessen the overall complexities in battery design.
With LMR, we can deliver over 400-mile range in our trucks while significantly reducing our battery costs,
The LMR chemistry will have zero to 2% cobalt, 30% - 40% nickel, and 60% - 70% manganese. That's significantly less than today's leading NMC cells, which are up to 10% cobalt and 80% nickel.
It's a huge, huge cost savings we'll get.
GM thinks it has cracked the problem.
