At -40°C, the battery reportedly retained more than 90% of its original capacity, a level of performance that is difficult to achieve with conventional lithium iron phosphate (LFP) batteries.
The EV industry has reached a quiet but important milestone. For the first time, a mass-produced passenger EV is set to use a sodium-ion battery, a technology long discussed but never deployed at this scale. The car in question is the Changan Nevo A06, developed by Changan Automobile and powered by batteries from CATL.
The announcement follows extensive winter testing in Inner Mongolia, where temperatures regularly drop well below what most EVs are designed to handle. According to the companies involved, the Nevo A06 was able to charge normally at around -30°C and continued operating at temperatures as low as -50°C.
