Global battery giant CATL has just made another major move!

🔸 Industry's First Mass-Produced Sodium Battery, Solving Electric Vehicles' "Winter Anxiety"

The most notable release is the "Light Commercial Low-Temperature Version" featuring the industry's first mass-produced sodium battery. According to the company's business director, this sodium battery has a capacity of 45 kWh, suitable for medium and small cargo vans or mini trucks.

Its biggest highlight is the impressive low-temperature performance: at -30°C (-22°F) when the battery cells are completely frozen, it can be plugged in and charged immediately without waiting for the battery to "warm up"; even in extreme cold environments of -40°C (-40°F), the battery still maintains 90% of its usable capacity. This means commercial electric vehicles in northern North America or mountainous regions no longer need to worry about breaking down due to low temperatures in winter.

🔸 Full Scenario Coverage, A Complete Suite of Commercial Electrification Solutions

In addition to the freeze-resistant sodium battery version, CATL has also released versions targeting other scenarios:

🔸 The "Marathon King" Version: 800km Range, and Lighter Too

The Tianxing II Light Commercial Long-Range Version boasts particularly impressive specifications: it features the commercial sector's largest single-pack capacity of 253 kWh, enabling a maximum range of 800 kilometers (497 miles). To put this in perspective, that's about the distance from New York to Cleveland and back.

Even more impressive is that it adopts CATL's "Taishan" battery pack architecture, which reduces vehicle weight by about 260 kilograms (573 pounds) while providing the same battery capacity, equivalent to removing the weight of three to four adults from the vehicle. This helps reduce energy consumption and increase cargo capacity.
