What battery chemistry does GM Ultium use?
Nickel-Cobalt-Manganese-Aluminum (NCMA) Chemistry: Ultium batteries feature an NCMA chemistry that reduces cobalt content by 70% compared to previous designs. This innovation not only cuts costs but also mitigates ethical and supply chain concerns associated with cobalt mining. The Ultium battery chemistry relies on a proprietary NCMA (nickel, cobalt, manganese, and aluminum) blend that balances energy density and cost-effectiveness. By reducing cobalt content by 70% and replacing it with more abundant aluminum, Chevrolet lowers production costs while increasing sustainability.General Motors announced a plan to drop the Ultium name from its EV batteries and technology, though the batteries themselves will still be used. The company also announced plans for a new battery-cell development center, with a target of early 2027 to start building battery cells.Advanced Chemistry GM has invested in advanced battery chemistry for the Ultium Platform, incorporating proprietary additives into lithium-ion cells.The cells manufactured by Ultium Cells LLC are large format, pouch-type cells that use a state-of-the-art nickel-cobalt-manganese-aluminum (“NCMA”) chemistry to deliver more range at less cost.
How is the Ultium battery different?
Ultium batteries boast a high energy density, storing more energy in a compact and lightweight package compared to conventional batteries. This results in enhanced range and performance for electric vehicles equipped with the Ultium Platform. DETROIT — General Motors will drop the name Ultium for its electric vehicle batteries and supporting technologies after spending years promoting the brand as it rethinks its EV and battery operations. The Detroit automaker confirmed the switch Tuesday ahead of an investor event.
