AESC has begun series production of its new 46120 cylindrical cells, which will power the all-electric BMW iX5. The cell measures 46mm by 120mm, offers up to 310Wh/kg energy density, and uses a nickel-rich cathode with a silicon-doped anode. The iX5 launches in late 2026 or early 2027 with a 141 kWh battery and 800-volt architecture.
