CATL to Begin Large-Scale Production of Sodium-Ion Batteries by 2026
CATL, the largest battery manufacturer globally, plans to initiate large-scale production of sodium-ion batteries by 2026, targeting applications in transportation, electric vehicles, and energy storage systems. The sodium-ion batteries, which offer advantages like a wide operational temperature range and lower production costs, have been developed under the brand Naxtra and can achieve a range of 500 km with an energy density of 175 kWh/kg. Despite their lower energy density leading to larger sizes, these batteries meet the upcoming Chinese national standards for electric vehicle batteries.

CATL, the world's largest battery manufacturer, announced at its year-end conference in Ningde that it will begin large-scale production of sodium-ion batteries by 2026. These batteries will be used in various sectors, including transportation, electric vehicles, commercial electric vehicles, and energy storage systems.
CATL previously launched a dedicated brand, Naxtra, for sodium-ion technology in April, and large-scale production has already started. The sodium-ion batteries offer advantages such as operation across a wide temperature range (-40 °C to 70 °C), lower production costs, longer lifespan, and higher safety standards.
However, they have lower energy density, resulting in larger and heavier batteries. CATL recently introduced a sodium-ion battery for electric vehicles with a range of 500 km, achieving an energy density of 175 kWh/kg. These batteries surpass the latest Chinese national standards for electric vehicle batteries, set to take effect in mid-2026.
