- The Changan Nevo A06 is the world's first mass-produced car powered by a sodium-ion battery.
- It has a CLTC range of about 250 miles and performs well in extreme cold (-40°F) with minimal range loss.
- CATL's Naxtra sodium-ion battery is set to debut in the Changan Nevo A06 by mid-2026.
- Sodium-ion batteries are safer, less temperature-sensitive, and cheaper than lithium-ion batteries.
- The Naxtra battery offers 175 Wh/kg energy density, similar to LFP batteries, making it suitable for low-cost EVs and energy storage.
- Cold-weather performance is a standout feature, with over 90% range retention at -40°F and stable power delivery at -58°F.
- CATL expects future sodium-ion batteries to reach up to 373 miles of range as the technology matures.
- The launch marks the beginning of a 'dual-chemistry era' where sodium-ion and lithium-ion batteries coexist to meet diverse needs.
