The global electric vehicle industry is entering a new phase as EV battery leader CATL confirms large-scale deployment of sodium-ion battery technology by the end of 2026. Already dominating the EV battery market, CATL is now positioning sodium-ion batteries as a strategic complement to lithium-ion solutions, aiming to lower costs, improve safety, and reduce dependence on lithium resources.
CATL’s Market Dominance Strengthens Its Next Move
As of October 2025, CATL held a commanding 38.1% share of the global EV battery market, widening its lead over competitors such as BYD, LG Energy Solution, CALB, and Gotion. This strong market position allows EV battery leader CATL to aggressively scale new technologies while maintaining supply stability across the EV ecosystem.
2026 Rollout Across Multiple Industries
At a supplier conference in December 2025, CATL confirmed that sodium-ion batteries will be ready for widespread commercial use by the end of 2026. Deployment will span passenger vehicles, commercial vehicles, battery swapping systems, and large-scale energy storage. The batteries are also expected to integrate with CATL’s battery-swapping infrastructure, accelerating adoption in urban mobility and fleet operations.
Naxtra Sodium-Ion Batteries: Performance Highlights
Introduced in April 2025, CATL’s sodium-ion lineup under the Naxtra brand delivers impressive specifications. The batteries achieve an energy density of 175 Wh/kg, comparable to top-tier LFP batteries. They support pure electric driving ranges exceeding 500 km and maintain up to 90% usable capacity in extreme cold conditions as low as -40°C, while operating safely up to 70°C.
Safety and Reliability Set New Benchmarks
CATL’s sodium-ion batteries became the first globally to meet China’s new GB 38031-2025 EV battery safety standards, which will officially take effect in July 2026. This milestone reinforces EV battery leader CATL’s focus on safety, durability, and regulatory readiness as the technology moves toward mass adoption.
Strategic Shift Toward Energy Freedom
Sodium-ion batteries play a key role in CATL’s “dual-star” strategy, complementing lithium-ion systems rather than replacing them. By reducing reliance on lithium—whose prices surged sharply in late 2025—CATL aims to stabilize costs and ensure long-term supply security. As production scales, sodium-ion battery costs are expected to drop significantly by 2030.
A Transformative Step for the EV Industry
With the potential to meet over 40% of domestic passenger vehicle demand in the future, sodium-ion batteries represent a major leap toward affordable, resilient, and sustainable electrification—further solidifying EV battery leader CATL’s role in shaping the next generation of energy technologies.
