Nearly 30 companies deploy sodium-ion batteries -Lithium - Ion Battery Equipment

In recent years, thanks to the rapid development of the new energy vehicle industry, the power lithium battery market has exploded in an all-round way. In addition to the widely used mainstream representative lithium-ion battery, the emergence of sodium batteries has once again stirred up the new battery market.

Recently, the National Development and Reform Commission, the Ministry of Industry and Information Technology and other departments have stated that they will take a series of measures to promote the healthy and orderly development of new batteries such as lithium-ion batteries and sodium-ion batteries. Under the policy overweight, the new track of sodium-ion batteries has also welcomed many senior players.(Lithium - Ion Battery Equipment)

Tang Kun, general manager of Zhongke Haina: Recently, sodium-ion batteries have received a lot of attention and are in a period of rapid development.

Tang Kun told reporters that the sudden popularity of sodium-ion batteries is related to the recent proposal by the Ministry of Industry and Information Technology and other departments to support sodium-ion batteries to accelerate the transformation of innovative achievements. Previously, industry giants such as CATL announced to enter the sodium-ion battery industry and plan to achieve basic industrialization in 2023.

The reporter learned that the production process of sodium-ion batteries is very similar to that of lithium-ion batteries and can be switched quickly. At present, some domestic lithium-ion battery upstream and downstream companies are also preparing for the industrialization of sodium batteries. Nearly 30 companies at home and abroad have made layouts for sodium-ion battery technology.

In addition, local governments such as Jiangsu, Shanxi and Guangdong are also accelerating the layout of the sodium-ion battery industry, and the construction of related projects has been launched in some industrial parks.

Sodium-ion batteries capture energy storage and low-speed electric vehicle markets

How long is the sodium-ion battery industry away from large-scale industrialization? What are the future application areas? What changes will it bring to the battery industry?

Reporter Pingyuan: In an industrial park in Liyang, Jiangsu, this sightseeing demonstration car with sodium-ion batteries is different from ordinary sightseeing cars. It is equipped with a sodium-ion battery with a storage capacity of 8 kWh and can last for about 100 kilometers. At present, the industrial chain of sodium-ion batteries is still in the early stage of commercialization.

It is understood that sodium-ion batteries are gradually being industrialized, the development cost is falling rapidly, and the energy density is about 4 times that of lead-acid batteries. It is expected to gradually replace them in the field of lead-acid battery applications.

Kang Libin, manager of the application development department of Zhongke Haina: Electric two-wheelers and sightseeing cars can use sodium-ion batteries, because this is an application area where lead-acid batteries are relatively easy to replace.

In addition, the reporter saw in the industrial park that a sodium-ion battery energy storage device is in operation. It uses valley electricity to store electricity at night, and then discharges it after the peak electricity consumption during the day, and uses the peak-to-valley difference in electricity prices to realize commercialization.

Hu Yongsheng, a researcher at the Institute of Physics, Chinese Academy of Sciences: In June this year, the world's first 1 MWh sodium-ion battery energy storage system was launched, which is the largest in the world. We are in an international leading position in these aspects.

At the Institute of Physics, Chinese Academy of Sciences, the staff showed reporters the latest sodium-ion battery products.

Yin Najiao, a staff member of the Institute of Physics, Chinese Academy of Sciences: Soft-pack lithium batteries are mainly used in low-speed electric vehicles, cylindrical batteries are now mainly used in electric bicycles, and aluminum shell batteries are used in energy storage power stations.

Industry insiders said that after the industrialization of sodium-ion batteries, a market of hundreds of billions of dollars will be formed in the fields of energy storage and other fields by virtue of its performance advantages.

Fan Xiulin, researcher at the School of Materials Science and Engineering, Zhejiang University: It is expected to develop rapidly in many fields such as low-speed electric vehicles, home and industrial energy storage, data centers, 5G communication base stations, smart grids, etc., to promote my country's competitiveness and influence in energy storage technology .
