CATL's Naxtra sodium-ion battery passes new national safety standards, ready for mass production


CATL‘s sodium-ion battery certified ahead of December mass production.

The new standard, set to be officially implemented on July 1, 2026, aims to eliminate fire risks in electric vehicles at the source by imposing strict safety requirements across multiple dimensions, including thermal diffusion, bottom impact, and fast-charging cycles. The Naxtra battery not only reduces dependence on lithium resources and creates a safer, lower-carbon battery ecosystem, but also addresses low-temperature performance issues in cold regions, promoting the adoption of new energy vehicles in China’s northern and other high-latitude areas. CATL has stated it aims to reach its goal of “1,000 stations by 2025” for its Chocolate battery swap network.
