Sodium hexafluorophosphate is the mainstream electrolyte for sodium-ion batteries, and the market has broad room for development.

Sodium hexafluorophosphate is an inorganic compound with the chemical formula NaPF6. It appears as a colorless crystalline powder and is easily soluble in water, methanol, ethanol, and acetone. Sodium hexafluorophosphate is an inorganic sodium salt that can be used in organic synthesis, electrolytes, catalysts, surfactants and other fields.

There are currently many methods for producing sodium hexafluorophosphate, including using hydrofluoric acid, phosphoric acid, and sodium hydroxide as raw materials, and producing sodium hexafluorophosphate through a series of chemical reactions such as mixing, stirring, heating, and filtration; A method of using phosphoric acid and sodium hydroxide as raw materials and a direct reaction to generate sodium hexafluorophosphate; a method of using phosphorus pentoxide and hydrogen fluoride as raw materials and a chemical reaction to generate sodium hexafluorophosphate.

According to the “China Sodium Hexafluorophosphate Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center , Sodium hexafluorophosphate has a wide range of uses. It can be used as a raw material to prepare other hexafluorophosphates; it can be used as an ion pairing agent to determine cobalt in water samples; it can be used as an electrolyte to prepare sodium ion batteries. Among them, electrolyte is the main downstream product of sodium hexafluorophosphate. The electrolyte prepared using sodium hexafluorophosphate has the advantages of high conductivity, high solubility, low production difficulty, and good compatibility. It has now become the mainstream electrolyte for sodium ion batteries. materials, the market development space is broad.

At present, many companies in my country have laid out the sodium-ion battery research and development track, and the planned domestic sodium-ion battery production capacity in 2022 will exceed 40GWh. In the future, as the industrialization process of sodium-ion batteries continues to accelerate, domestic demand for sodium hexafluorophosphate electrolyte and its raw material sodium hexafluorophosphate is expected to continue to grow.

Driven by the continued growth in demand, the number of domestic companies in the production field of sodium hexafluorophosphate is increasing. The main companies include Duofuo New Materials Co., Ltd., Zhejiang Zhongxin Fluorine Materials Co., Ltd., Shanxi Huayang Group New Energy Co., Ltd., and Tianji New Energy Technology Co., Ltd., Guangzhou Tianci High-tech Materials Co., Ltd., etc.

Among them, Duofuoduo is currently the leading company in the domestic hexafluorophosphate phosphorus industry and is also the first company in my country to achieve commercial mass production of sodium hexafluorophosphate. The company’s current production capacity of sodium hexafluorophosphate has reached 1,000 tons. In the future, as local companies continue to upgrade their technologies, my country’s sodium hexafluorophosphate output is expected to continue to increase, and the industry development trend is improving.

Industry analysts said that sodium hexafluorophosphate is an important type of inorganic sodium salt, which is mainly used as Electrolytes are used in sodium-ion battery production scenarios. In recent years, as the industrialization process of domestic sodium-ion batteries continues to accelerate, the demand for sodium hexafluorophosphate continues to increase, and the market development space is broad. At present, many companies in my country have achieved mass production of sodium hexafluorophosphate, and a leading company in the industry, polyfluorophosphate, has emerged. In the future, the production capacity of sodium hexafluorophosphate is expected to continue to increase, promoting the rapid development of the industry.
