Overview
- Winter trials in Inner Mongolia and Mongolia reported normal charging around −30°C, operation down to −50°C, and more than 90% capacity retention at −40°C. Changan’s Nevo A06 is slated to be the first mass-produced passenger EV with CATL’s sodium-ion pack in China by mid-2026, using a 45 kWh battery rated at over 400 km on the CLTC cycle.
- CATL engineer Ouyang Xiaolong said the Naxtra chemistry can function in environments such as Antarctica, citing tests conducted at −50°C.
- Analysts highlight advantages in low-temperature performance, safety and materials availability, alongside current drawbacks in energy density and cycle life versus lithium-ion.
- Independent, real-world validation and wider international rollout are still pending, with CATL positioning sodium-ion to complement rather than replace lithium-ion across use cases.
