The Rise of Sodium-Ion Batteries in Electric Vehicles

As the undisputed global leader in EV battery production, CATL is continuously reshaping the electric vehicle landscape with groundbreaking chemistry. Traditional lithium-ion and LFP batteries have long dominated the market, but they often struggle with extreme cold and rely heavily on costly, constrained minerals.

To solve these hurdles, CATL has officially kicked off mass production for its advanced 45 kWh sodium-ion battery packs. Achieving an impressive energy density of 175 Wh/kg, these innovative cells are designed to handle rigorous everyday driving while utilizing vastly more abundant raw materials.

One of the most remarkable breakthroughs of this new technology is its resilience in brutal winter conditions. While standard batteries often lose significant range and power when temperatures plummet, CATL's sodium-ion packs can effortlessly charge in freezing environments down to -30°C. Even when tested at an extreme -40°C, the system still manages to retain an astonishing 90% of its usable capacity, offering over 10,000 charge cycles for long-term durability.
