CATL Set to Start Mass Production of Sodium-Ion Traction Batteries in 2026

• May 31, 2026

Contemporary Amperex Technology Co. Limited (CATL), a leading manufacturer in the battery industry, has announced it will commence mass production of sodium-ion traction batteries within 2026. This development marks a significant step forward in CATL’s strategy to diversify battery technologies beyond conventional lithium-ion cells.

Progress on Sodium-Ion Battery Production and Future Technologies

Late last year, CATL expressed intentions to initiate large-scale manufacturing of sodium-ion batteries but indicated some uncertainties remained regarding the timeline. These challenges have now been addressed, allowing the company to move ahead with full-scale production plans as initially anticipated for this year.

Sodium-ion batteries offer a promising alternative to lithium-ion cells, particularly in applications requiring large-capacity traction batteries such as electric vehicles. Due to the abundance and lower cost of sodium compared to lithium, these batteries have the potential to reduce reliance on scarce materials and lower overall production expenses, thereby supporting more sustainable and cost-effective energy storage solutions.

Alongside its sodium-ion initiatives, CATL is also engaged in the research and development of lithium-air battery technology. This emerging battery type is expected to be significantly lighter than current lithium-ion options, which could lead to substantial improvements in energy density and weight reduction for electric vehicle applications in the future.

CATL’s advancements in battery technologies reflect an ongoing effort to expand the electric vehicle ecosystem with innovative energy storage solutions. By pursuing both sodium-ion and lithium-air batteries, the company aims to cover diverse needs across the market, from cost-sensitive mass-market vehicles to high-performance applications requiring cutting-edge battery performance.

The timeline for when sodium-ion batteries will become widely available in commercial products remains tied to CATL’s production ramp-up and industry adoption rates. However, the confirmation of mass production starting this year indicates growing confidence in the commercial viability of this technology.

As the battery market continues to evolve rapidly, developments like these contribute to the broader push toward electrification and the reduction of carbon emissions in transportation and energy sectors worldwide.

CATL confirms plans to begin large-scale manufacturing of sodium-ion traction batteries this year, advancing alternatives to traditional lithium-ion cells.
