CATL Launches Sodium-Ion Batteries for Passenger EVs in 2026, Targeting 370+ Miles Range
Key Takeaways
- ▸CATL's sodium-ion batteries will launch in passenger EVs by end of 2026, starting with Changan Nevo A06, offering ~370 miles of range
- ▸Technology overcomes four critical engineering challenges, enabling full-scale mass production with GWh-level industrialization capacity
- ▸Sodium-ion batteries offer superior cold-weather performance and sustainability advantages as a lithium alternative, though CATL aims to match LFP energy density within three years
Summary
CATL, the world's leading EV battery manufacturer, announced during its Tech Day Event that sodium-ion batteries will begin rolling out in passenger electric vehicles by the end of 2026. The company's Naxtra sodium-ion battery marks a transition from laboratory breakthrough to large-scale manufacturing, with the first mass-produced EV featuring this technology being the Changan Nevo A06. CATL has overcome four key engineering barriers—extreme water control, gas generation in hard carbon, aluminum foil adhesion, and self-forming anode systems—to enable GWh-level industrialization.
The sodium-ion batteries currently achieve an energy density of approximately 175 Wh/kg and deliver up to 600 km (372 miles) of CLTC driving range. CATL aims to match the energy density of lithium iron phosphate (LFP) batteries within three years. The technology offers significant advantages, including superior performance in extreme cold temperatures (retaining 90% usable capacity at -40°C) and providing a more sustainable alternative to lithium-based batteries given sodium's abundance. The company also revealed its third-generation Shenxing Ultra-fast charging battery, capable of a full recharge in just 6 minutes and 27 seconds.

Editorial Opinion
CATL's sodium-ion battery launch represents a significant milestone in EV battery diversity, offering a compelling alternative to lithium-dominant supply chains while addressing cold-climate performance gaps. The achievement of GWh-level production readiness demonstrates that sodium-ion technology has transitioned from promising research to viable manufacturing, though the company's target to match LFP energy density within three years will be critical to widespread adoption. This development could reshape battery sourcing strategies and reduce geopolitical supply chain risks, though early performance metrics suggest sodium-ion will initially serve as a complementary rather than replacement technology for premium long-range vehicles.
