Ultium Cells manufactures large-format pouch cells using nickel-cobalt-manganese-aluminum (NCMA) chemistry with a modular design. Key innovations include a wireless Battery Management System developed with Analog Devices to reduce wiring and system volume. The company offers multiple chemistries (NMC and planned LFP), automated manufacturing with advanced quality control, and cells that deliver ranges exceeding 400 miles per charge. Cells integrate with GM’s Ultium platform and can be stacked vertically or horizontally.
