The sodium-ion battery industry is still in the early stages of industrialization and has huge potential for future market development.

A sodium-ion battery is a secondary battery that relies on the movement of sodium ions between the positive and negative electrodes. In sodium-ion batteries, the positive electrode material usually requires the use of Prussian blue, nickel iron manganese layered oxide and other active materials with advantages such as thermal stability and safety; the negative electrode material usually has the characteristics of small volume deformation and good chemical stability. of hard carbon material. Compared with other batteries, sodium-ion batteries have fast charging capabilities, high energy density, and long cycle life. There are currently a variety of sodium-ion batteries on the market, such as solid-state sodium-ion batteries, organic sodium-ion batteries, sodium-sulfur batteries, aqueous sodium-ion batteries, etc. Among them, sodium-sulfur batteries are currently the only energy storage devices with both large capacity and high energy density. Battery.

my country’s sodium-ion battery industry is still in the early stages of development and has not yet achieved large-scale production. There are currently many domestic sodium-ion battery-related patents, and the number of applications is still showing a growing trend, reaching 630 in 2021, reaching a record high. Currently, most of the applicants for sodium-ion batteries are universities and research institutes, among which Shaanxi University of Science and Technology and Central South University have the highest number of sodium-ion battery patent applications.

Sodium-ion batteries are mainly used in the fields of electric two-wheelers and electrochemical energy storage. In terms of electric two-wheeled vehicles, with the promotion of shared bicycles, the production and sales of electric two-wheeled vehicles in my country have shown a growth trend, reaching 51.24 million and 47.66 million units respectively in 2020. Affected by the long-term impact of the new crown epidemic, my country’s electric two-wheeled vehicle sales have decreased slightly, with sales in 2021 reaching 42 million units. Although the sales of electric two-wheelers are slightly declining, the overall market is huge, which is good for the development of the lithium-ion battery industry.

According to the released “2022-2026 Sodium Ion Battery Industry In-depth Market Research and Investment Strategy Suggestions Report” shows that in electrochemical storage In terms of energy, with the continuous optimization of my country’s energy structure in recent years, the installed capacity of electrochemical energy storage has continued to grow, from 0.4GW in 2017 to 5.6GW in 2021. my country’s electrochemical energy storage is growing rapidly and has huge market development potential in the future, providing space for the development of the sodium-ion battery industry.

Due to the good development prospects of the sodium-ion battery industry, it has attracted the deployment of many companies. In the past ten years, the cumulative number of companies in my country has reached about 200. Among them, the more representative companies include CATL, Sacred Sun, Penghui Energy, and Xinzhu Co., Ltd., Huayang Co., Ltd., Mingtai Aluminum, Nanfeng Chemical, Huayang Co., Ltd., Xinzhu Co., Ltd., Xinwangda, etc.

Industry analysts said that sodium-ion batteries are mainly used in the fields of electric two-wheeled vehicles and chemical energy storage. At present, my country’s chemical energy storage It is still in the early stages of development and has huge potential for future market development, which is good for the development of the sodium-ion battery industry. As the sodium-ion battery industry has good development prospects and has attracted many companies, no company has yet achieved industrialization development. The market is still in the early stages of industrialization, and there are still development opportunities for new entrants.
