In a world where innovation is key, CATL, the Chinese battery giant, is taking a bold step into the future. At a conference in Ningde, the company announced its intention to produce sodium-ion batteries on a large scale by 2026, thus promising a new era for electric vehicles and energy storage systems.
A groundbreaking announcement
During this end-of-year conference, CATL revealed its strategy for the coming years. As the largest battery manufacturer in the world, the company is well aware of the challenges related to the energy transition. With this announcement, it is preparing to bring sodium-ion batteries to market, intended not only for electric cars but also for commercial vehicles and stationary storage systems.
This initiative comes at a time when the demand for sustainable energy solutions is skyrocketing. By developing this technology, CATL hopes to meet the growing needs of consumers while respecting the environment.

Advantages and disadvantages of sodium ions
Research on sodium-ion batteries is not new. For several months, CATL has intensified its efforts in this area, particularly with the launch of Naxtra, a brand dedicated to this technology. Last spring, it began large-scale production of these batteries.
The advantages of sodium-ion batteries are numerous. They operate over a wide temperature range, from -40 °C to 70 °C, which is particularly interesting for various applications. Additionally, their production costs are lower, their lifespan is extended, and they meet higher safety standards than traditional lithium-ion batteries. However, the downside lies in a lower energy density, resulting in generally larger and heavier batteries. Imagine carrying a backpack filled with sand instead of feathers – that’s the idea.

A mature technology
Three months ago, CATL took a step forward by presenting a sodium-ion battery capable of offering a range of 500 km for electric cars. This impressive result was made possible thanks to an energy density reaching 175 Wh/kg. To give you an idea, it’s like having a gas tank that never empties – or almost.
CATL’s sodium-ion batteries have also surpassed the latest Chinese national standard for batteries intended for electric vehicles, which will come into effect in mid-2026. The company has made it a point to enhance the safety of its product while providing exceptional performance at low temperatures, thus outperforming traditional lithium-ion batteries. It’s a bit like moving from an old gas stove to an induction cooktop – the difference is immediately noticeable.
An anticipated commercial launch
The commercial launch of sodium-ion batteries by CATL is scheduled for 2026. This timeline perfectly aligns with the company’s strategy to develop different technologies for various applications. The automotive world is undergoing a transformation, and this innovation could redefine market standards.
In summary, CATL is not just following trends: it is creating them. With its ambitions in sodium-ion batteries, the Chinese manufacturer is positioning itself as a key player for the future of electric transportation and energy storage systems. Stay tuned, as this technological shift could change the way we move and interact with our environment.
