BAIC Group has completed its first sodium-ion EV battery prototype, achieving 450 km CLTC range, 11-minute full charge via 4C ultra-fast charging, and over 170 Wh/kg energy density. The battery operates across -40°C to 60°C and retains over 92% energy at -20°C. This follows CATL and Changan's launch of the world's first mass-produced sodium-ion EV. Global sodium-ion shipments hit 9 GWh in the past year, up 150%, with projections exceeding 1,000 GWh over the next four years. Chinese manufacturers are betting on sodium-ion as a lower-cost alternative to lithium amid rising lithium prices.
