CATL is developing the second generation of sodium batteries, which have performance close to that of lithium iron phosphate batteries.

In a recent investor relations event, CATL announced that they are developing second-generation sodium batteries, whose performance indicators are already comparable to those of lithium iron phosphate batteries. If mass production is achieved, the cost of sodium batteries will be more advantageous than that of lithium iron phosphate batteries. CATL's first-generation sodium battery was launched in 2021, with the characteristics of high energy density, fast charging capability, excellent thermal stability and low-temperature performance. The product's battery cell energy density reaches 160Wh/kg, which can be fully charged to 80% in 15 minutes, and can maintain a discharge rate of more than 90% even in a low temperature environment of -20°C.
