Catl’s name may not sound to you if you don’t follow the world of the electric car closely, but we are talking about the main battery manufacturer worldwide. Tesla, Mercedes-Benz, BMW or Volkswagen are some of the giants who trust their products.
Now, this Chinese colossus wants to go one step further. The focus is in sodium ion batteries, a technology that timidly presented in 2021 and now wants to boost on a large scale.
Naxtra: The new battle horse. The next Catl movement is called Naxtra, its new sodium batteries line. The company plans to start mass production in the coming months, with an eye on its strategic partners and the global deployment of the product.
Less lithium, more sodium. Sodium, more abundant and cheap than lithium, allows to reduce the dependence of the latter and strengthen the basis of new energy technologies. According to Ouyang Chuying, Catl R&D co -director, sodium ion batteries could have a cost advantage as the supply chain strengthens.
A range, two solutions. Catl has developed two versions of its Naxtra batteries: one for passenger electric vehicles and a 24 V one with integrated Start-Stop system, designed for heavy trucks. Both are designed to perform in extreme conditions, from -40 ° C to +70 ° C.
Extreme cold, the battery for cars maintains 90 % of its capacity. Even with only 10 % load, it retains stable performance at -40 ° C, without significant losses of power.
Autonomy, cycles and security. The tourism version reaches an energy density of 175 Wh/kg, the highest recorded in sodium batteries, in line with LFP. It promises an autonomy of 500 km and more than 10,000 load cycles, which reduces maintenance costs remarkably.
And, above all, it improves security. By eliminating combustion -prone materials, Catl claims to have gone from passive protection to intrinsic security. The sodium, by its own chemistry, has fewer fire risks in electric vehicles.
