Industrialization Process of Sodium ion Battery in 2024

Industrialization process in 2024

In 2024, sodium ion battery technology has developed rapidly, especially achieving significant breakthroughs in energy density, cycle life, and safety. With the continuous maturity of technology and the growth of market demand, the industrialization process of sodium ion batteries is accelerating.

In practical applications, sodium ion batteries have begun to be applied in some fields. For example, Jianghuai Automobile Group's world's first mass-produced sodium battery model, the sodium battery version of the Flower Fairy electric vehicle, has been delivered to users, while Jiangling Group's new energy vehicle, the Jiangling Yizhi EV3 (Youth Edition), equipped with Funeng Technology's sodium ion battery, has also been officially launched.

The strategic cooperation agreement signed between Zhongna Energy and Tailing Technology plans to provide the latter with no less than 2 million sets of Poly Sodium 1 sodium ion battery packs within two years, and is expected to start mass production and delivery in the third quarter of this year, marking a new stage of large-scale production for sodium ion batteries from the small batch trial stage.

Overall, although the development of sodium ion batteries in the two wheeler and passenger car markets did not meet expectations in 2024, they are still dominant in the energy storage field, and the number of companies releasing new sodium battery products is increasing, indicating that the sodium battery industry has made significant progress in product research and development in the past year.

In the rapid development of sodium ion batteries today, there are several key issues that urgently need to be addressed.

Firstly, sodium ion batteries are a battery system different from lithium-ion batteries. Directly applying lithium-ion battery electrode materials to the research of sodium ion batteries is a shortcut. However, finding new positive electrode materials with high energy density and power density, as well as negative electrode materials with small volume changes during cycling, is an important way to improve the performance of sodium ion batteries and the key to their early application in large-scale energy storage.

Secondly, at present, the synthesis methods of electrode materials for sodium ion batteries are relatively simple. The traditional solid phase method and gel sol method are the main preparation methods, and there is little research on the modification of electrode materials Finding simpler and more efficient synthesis methods, while conducting modification research on materials with better performance, is also a way to improve the performance of sodium ion batteries.

Thirdly, safety issues are an important factor restricting the development of lithium-ion batteries, and sodium ion batteries will also face safety tests under large-scale applications. Therefore, developing new electrolyte systems and studying safer gel state and all solid state electrolytes are important directions to alleviate the safety problems of sodium ion batteries.
