New EV battery That's Made From Salt Could Last For 3,600,000 Miles
14 Aug 2025 | Abstracted from Road and Track
CATL's new Naxtra sodium-ion "salt" EV battery costs just $10–$19/kWh - about one-tenth of current lithium-ion prices (~$100–$115/kWh). It retains 85% capacity after 3.6M miles, charges at up to 5C (full in ~12 min), and goes 30–80% in 30 min even at –30 °C with ~93% usable capacity. The low cost, long life, and cold-weather performance could transform EV affordability and durability.
