China is the world’s largest producer of electric vehicle batteries. CATLat the World Young Scientists Summit held on November 18 second generation sodium battery introduced. According to the statements of CATL’s chief scientist Wu Kai, these innovative batteries will be launched in 2025. However, the mass production process 2027 It is not expected to start until next year.

Low temperatures will not be a problem

CATL’s new generation sodium-ion battery draws attention especially with its low temperature durability. These batteries At extremely low temperatures such as -40°C It can even be discharged normally. Although current data in terms of energy intensity is not disclosed, the company’s goal is to 200 Wh/kg of water.

Wu Kai stated that the new batteries not only offer durability in cold weather conditions but also increase safety performance. These features make sodium-ion batteries an attractive option for vehicles and devices that will be used in cold climates.

Sodium-ion batteries work similar to lithium-ion batteries in terms of energy storage mechanism. Currently, sodium-ion batteries have better characteristics in terms of safety and low temperature resistance; but they do not have as high an energy density as lithium-ion.

Costs will decrease over time

While theoretically sodium-ion batteries are expected to be more cost-effective, they are currently more expensive than lithium-ion batteries due to the small production scale. However, companies such as CATL and BYD aim to make these batteries more competitive by reducing production costs. BYD predicts that sodium-ion batteries will reach similar costs to lithium-iron-phosphate batteries by 2025, and in the long term, this cost may fall 70 percent below.

CATL’s first generation sodium-ion battery was introduced in 2021 and attracted attention with its high energy density, fast charging capacity, thermal stability and low temperature performance. The company’s new generation sodium-ion batteries are expected to replace lithium-ion batteries by 20-30 percent, especially in short-distance electric vehicles.

On the other hand, BYD started its sodium-ion battery production project with an annual capacity of 30 GWh at the beginning of 2024. These batteries, which are currently produced with an energy density of 105 Wh/kg, are planned to reach 130 Wh/kg in the coming years. CATL’s 200 Wh/kg target is seen as a very ambitious target for the sector.
