As the world's first sodium-ion battery to achieve mass production, CATL's new sodium-ion battery has an energy density of up to 175Wh/kg, can work stably in the full temperature range from -40°C to 70°C, and has a cycle life of up to 10,000 times. This breakthrough completely breaks the industry bottleneck of sodium-ion batteries in terms of low temperature attenuation and energy density. The core lies in the innovation of atomic-level materials, through the composite antifreeze electrolyte and nano-level electrode structure design, so that the battery can still maintain 90% of the available power at minus 40 °C, and the vehicle power has no attenuation at 10% low power, realizing the miracle of "extreme cold as normal temperature".
In the field of passenger cars, the new sodium power battery supports 5C peak charging and has a range of up to 500 kilometers. Its materials are intrinsically safe, cobalt-free and nickel-free, and the risk of thermal runaway is reduced by 70%, jumping from "passive fire prevention" to "intrinsic safety", becoming the first choice for high cost performance of A0 class models. In the field of commercial vehicles, the new 24V heavy truck start-up integrated battery with 8 years of ultra-long life and 61% cost reduction (compared with lead-acid batteries), as well as full charge deep discharge capacity (lead-acid batteries only support 30%), leading commercial vehicles into a new era of "vehicle and electricity life". Its characteristics of "one-key start at minus 40 °C" and "can still be started after a long time" completely solve the pain point of traditional battery failure in winter.
The commissioning of CATL's sodium battery production line not only marks the maturity of sodium-ion battery technology, but also promotes the accelerated development of supporting links such as hard carbon anodes and aluminum-based current collectors. It is estimated that by 2027, the global installed capacity of sodium batteries will exceed 150GWh, leading the "de-lithiation" process in the fields of energy storage, two-wheeled vehicles, and low-speed electric vehicles, and significantly weakening the impact of lithium resource price fluctuations on the industry.
