As the electrolyte solute lithium salt, the market share of lithium hexafluoroarsenate (LiAsF6) needs to be increased.

There are many types of lithium salts, including lithium hexafluoroarsenate, lithium hexafluorophosphate, lithium hexafluorantimonate, lithium bisoxaloborate, lithium tetrafluoroborate and lithium perchlorate. Lithium hexafluoroarsenate is an inorganic lithium salt with the chemical formula LiAsF6. It appears as white crystals or powder and is soluble in water. Lithium hexafluoroarsenate has the advantages of good electrochemical stability, high ionic conductivity, good thermal stability, and good film-forming properties. As an electrolyte solute lithium salt, it is widely used in the field of lithium-ion batteries.

Lithium hexafluoroarsenate is a fluorine chemical product. my country’s fluorine chemical industry started late, but is developing rapidly. With the gradual implementation of national environmental protection policies and taking effect, my country’s fluorine chemical industry has gradually developed in a green and environmentally friendly direction, and its output has shown a steady growth trend, reaching 3.897 million tons in 2022. In the future, as the prosperity of the fluorine chemical industry increases, lithium hexafluoroarsenate is expected to gain broad market space.

The lithium-ion battery field is the largest demand end for lithium hexafluoroarsenate. As an electrolyte solute lithium salt, lithium hexafluoroarsenate has excellent comprehensive properties and can be used to produce disposable lithium-ion batteries. In recent years, with the accelerated development of downstream industries, my country’s demand for lithium-ion battery applications has continued to grow, and its output has continued to increase. According to statistics from the Ministry of Industry and Information Technology, in the first half of 2023, my country’s lithium-ion battery production exceeded 400GWh, a year-on-year increase of more than 43%. The growth in lithium-ion battery production will provide favorable conditions for the development of the lithium hexafluoroarsenate industry.

According to the “2023-2028 China Lithium Hexafluoroarsenate (LiAsF6) Industry Market In-depth Research and Development Prospects Forecast Report span>》shows that the performance of lithium hexafluoroarsenate is similar to that of lithium hexafluorophosphate. Lithium hexafluorophosphate is the most widely used electrolyte solute lithium salt. It has the advantages of good oxidation resistance, low toxicity, high conductivity, and simple synthesis process. Benefiting from the improvement of technology maturity and strong market demand, my country’s lithium hexafluorophosphate output has maintained a long-term growth trend, reaching 134,000 tons in 2022, setting a record high. Compared with lithium hexafluorophosphate, lithium hexafluoroarsenate is more toxic and is currently mostly used in the research process of lithium-ion batteries, with a lower market share.

The main players in the global lithium hexafluoroarsenate market include American Alfa Company, American Elements Company, British Fluorochem Chemical Company, etc. In terms of the local market, my country’s lithium hexafluoroarsenate market has few participants, dominated by small and medium-sized enterprises. Baishun Biological, Haorui Chemical, Huzheng Biological, West Asia Reagents, Xinyang Ruihe Chemical, etc. are the main suppliers of lithium hexafluoroarsenate in my country.

​​  Industry analysts said that lithium hexafluoroarsenate, as the electrolyte solute lithium salt, has good industry development prospects. However, at present, due to the toxicity of lithium hexafluoroarsenate, its market share is relatively low, and lithium hexafluorophosphate occupies the dominant position in the electrolyte solute lithium salt market. It is expected that in the future, with the increasing application demand for fluorine chemical products and the improvement of independent research and development capabilities of local enterprises, the development speed of the lithium hexafluoroarsenate industry will further accelerate.
