Half the price, five times more lifespan, leading energy density, and extreme weather protection. That’s the promise, as CATL unveils a new sodium-ion EV battery that is set to rewrite the entire industry.
CATL previously announced in April that its Naxtra sodium-ion battery would begin mass production in December 2025, with initial deployment in its Choco-swap electric vehicle models. The battery maintains 90% usable capacity at temperatures as low as -40°C and features an energy density of 175Wh/kg, comparable to lithium iron phosphate batteries. It supports peak charging rates of 5C, offers a 500km range, and has a lifespan exceeding 10,000 cycles.
