On February 5, Changan Automobile unveiled its global sodium-ion battery strategy, and the world's first mass-produced sodium-ion battery passenger vehicle was officially introduced. Test data shows that the vehicle equipped with CATL's sodium-ion battery delivers nearly three times the discharge power compared to conventional lithium iron phosphate vehicles with the same battery capacity under -30°C conditions. In extreme cold environments of -40°C, it maintains over 90% capacity retention, and it can still discharge stably even at the extreme low temperature of -50°C.
