CATL will begin mass production of sodium-ion batteries in 2026, according to recent company announcements and industry reports. The Chinese battery giant plans to scale production at its facilities in Qinghai and Guangxi provinces, targeting initial capacity of 10-20 GWh annually for automotive and energy storage applications.

When Will CATL Start Mass Production of Sodium-Ion Batteries?

CATL’s sodium-ion battery mass production is scheduled for 2026, following successful pilot production that began in 2023. The company first unveiled its first-generation sodium-ion battery in July 2021 with an energy density of 160 Wh/kg. The 2026 timeline represents a strategic shift as lithium prices remain volatile and automakers seek cost-effective alternatives for entry-level EVs.

What Are the Key Advantages of Sodium-Ion Batteries?

Sodium-ion batteries offer several compelling benefits: 30-40% lower material costs compared to lithium-ion, superior cold-weather performance down to -20°C, and elimination of supply chain constraints since sodium is abundantly available. CATL’s technology also features faster charging capabilities—reaching 80% capacity in just 15 minutes—making them ideal for budget EVs and grid storage.

How Does This Impact the EV Market?

CATL’s mass production will enable automakers like Chery and JAC Motors to launch EVs priced under $15,000, primarily targeting markets in China, Southeast Asia, and Latin America. While energy density remains lower than lithium alternatives (160 Wh/kg vs. 250+ Wh/kg), sodium-ion batteries are perfectly suited for compact city vehicles with 250-300 km range requirements, potentially capturing 10-15% of the global EV battery market by 2028.
