CATL's Sodium-Ion Batteries Enter Mass Production for Vehicles

[Technological Breakthrough] CATL's sodium-ion batteries have officially been installed in Changan Automobile's mass-produced passenger vehicles, marking the beginning of a dual-track era for sodium and lithium battery technologies.

Key Development: The World’s First Mass-Produced Sodium-Ion Battery Vehicle Debuts; Multiple Brands to Adopt Widely

On February 5, CATL and Changan Automobile jointly unveiled the world’s first mass-produced passenger vehicle powered by sodium-ion batteries in Yakeshi. Going forward, Changan’s brands—including Avatr, Deepal, Qiyuan, and Gravity—will all adopt this battery technology, addressing over 50% of the range requirements in the new energy vehicle market.

Key Specifications: Industry-Leading Low-Temperature Performance and Energy Density

Equipped with third-generation CTP technology, the sodium-ion battery achieves a cell energy density of 175 Wh/kg, enabling a pure electric driving range exceeding 400 km. At -30°C, its discharge power is nearly three times that of lithium iron phosphate (LFP) vehicles. It maintains over 90% capacity retention at -40°C and can still deliver stable discharge performance even at an extreme low of -50°C.

Strategic Foundation: Hedging Against Lithium Price Volatility and Strengthening Supply Chain Security

Amid renewed increases in lithium carbonate prices, sodium-ion batteries—thanks to abundant raw materials and cost advantages—represent a critical strategic investment from CATL’s multi-billion-dollar R&D initiative, accelerating the new energy vehicle industry into a new phase characterized by diversified technological pathways.
