GM's New Battery Tech Could Be a Breakthrough for Affordable EVs

The earliest NMC cells utilized astir adjacent thirds of nickel, manganese, and cobalt. GM’s existent “high-nickel” Ultium cells swapped retired overmuch of that cobalt for nickel, portion adding aluminum arsenic well. They use, said GM artillery technologist Andy Oury, astir 5 percent cobalt and 10 percent manganese, with the remainder being nickel and aluminum.

The LMR cells, however, substitute manganese—which is cheaper and much globally plentiful—for immoderate of the pricier nickel and virtually each of the cobalt. They are, Oury said, 60 to 70 percent manganese, 30 to 40 percent nickel, and lone up to 2 percent nickel.

The caller chemistry, successful a 2nd benignant of cell, volition besides usage a caller module format. Standardized Ultium NMCA modules for each conveyance were the close solution for GM to motorboat its existent lineup of 12 antithetic EV models, its execs said. Going forward, the institution envisions utilizing antithetic chemistries for antithetic purposes: NMCA for high-performance and its astir susceptible models, present LMR for agelong scope astatine little cost, and LFP for its slightest costly models.

Cheap Long-Range Electric SUVs and Trucks

So if LMR chemistry really produces a compartment that costs arsenic small to marque arsenic LFP with greater vigor density, that could beryllium a crippled changer—including for North American competitiveness against China successful the captious sphere of artillery improvement and production.

“LMR volition complement our high-nickel and iron-phosphate solutions to grow lawsuit prime successful the motortruck and full-size SUV markets,” said Kurt Kelty, GM’s vice president of battery, propulsion, and sustainability. It will, helium said, “advance American artillery innovation, and make jobs good into the future.”

Specifically, LMR packs volition little the outgo of immoderate full-size EV motortruck and SUV models to bring their prices person to those of their gasoline counterparts. That’s important to boosting income of the full-size EV models, which person not truthful acold reached the aforesaid volumes and marketplace penetrations arsenic those of GM’s compact and midsize EV crossovers.
