GM altered the chemistry of its battery cells, in a move that’s distinct from most EV batteries in production today. The majority of batteries are made with NCM — nickel, cobalt, and magnesium. The Ultium batteries will add aluminum — so NCMA — and reduce the cobalt content by 70 percent. GM has also reduced by about 80 percent the amount of wiring from the EV architecture currently used in its Chevy Bolt vehicles. The hope is that this will drive battery cell costs below the $100/kWh level and allow GM to get more bang for its buck as it scales up its EV production capabilities.
"an estimated 400 miles of range"

Ultium-powered EVs are designed for Level 2 and DC fast charging, GM says. Most will have 400-volt battery packs and up to 200kW fast-charging capability while the company’s truck platform will have 800-volt battery packs and 350 kW fast-charging capability. GM says it wants to address the two main pain points of EV ownership: cost and charging time.
