Have you ever wondered if the future of electric vehicles could do without lithium? With the rise of electromobility, the quest for alternative resources becomes essential. CATL, the Chinese battery giant, is exploring new ways to meet these challenges. Discover how this company plans to transform the battery landscape with an innovative approach.
The 3 key facts not to miss
- CATL plans to launch its sodium-ion batteries by the end of 2026.
- The Naxtra battery offers a capacity of 175 Wh/kg and a range of 500 km.
- Sodium-ion batteries are safer and operate at extreme temperatures.
CATL and sodium-ion innovation
CATL, recognized as the global leader in batteries for electric vehicles, highlights a major innovation: sodium-ion batteries. During a conference held on December 28, the company announced that these new batteries would be marketed by the end of 2026. This development is based on extensive research conducted by CATL, aiming to offer a viable alternative to lithium-ion batteries.
The characteristics of Naxtra batteries
The manufacturer’s first sodium-ion battery, Naxtra, was unveiled in April. This battery promises impressive performance, with an energy density of 175 Wh/kg, similar to LFP batteries. In addition to reducing dependence on lithium, sodium-ion batteries eliminate significant risks associated with spontaneous combustion. Another notable advantage is their compatibility with extreme temperatures, operating efficiently between -40°C and +70°C.
Increased range and safety
CATL’s sodium-ion batteries are designed to offer a range of 500 km, positioning the Naxtra as a competitive option in the electric vehicle market. Furthermore, these batteries retain 90% of their capacity even at -40°C, ensuring increased reliability in harsh weather conditions.
CATL: the pursuit of global leadership
By developing this new technology, CATL asserts its desire to maintain its dominant position in the market. According to SNE Research, CATL held a market share of 38.1% in 2025, with BYD in second place at 16.9%. This technological advancement could further strengthen CATL’s supremacy in the battery industry.
