Chinese battery giant CATL and automaker Changan Automobile are preparing to put the world’s first passenger car powered by sodium‑ion batteries on public roads by mid‑2026. If successful, the launch could reduce fire risk in electric vehicles and improve performance in extreme temperatures.

Technical Specifications

• Battery: CATL Naxtra sodium‑ion battery
• Vehicle: Changan Nevo A06 sedan
• Estimated range: ~400 km (249 mi) on the China Light‑Duty Test Cycle
• Energy density: 175 Wh kg⁻¹ (comparable to lithium‑ion phosphate, lower than nickel‑rich chemistries)
• Planned rollout: Across Changan’s broader portfolio, including EVs from Avatr, Deepal, Qiyuan, and Uni

“The launch represents a major step in the industry’s transition toward a dual‑chemistry ecosystem, where sodium‑ion and lithium‑ion batteries complement each other to meet diverse customer needs,” CATL said in a press release.

Cold‑Weather Performance

• CATL reports that the Naxtra battery’s discharge power at ‑30 °C (‑22 °F) is three times higher than that of lithium‑ion phosphate batteries, highlighting its advantage in low‑temperature conditions.
