Battery grade lithium fluoride (LiF) is the core raw material of lithium hexafluorophosphate and there are many manufacturers in my country

Lithium fluoride is an inorganic compound that appears as a white powder and is widely used in medicine, chemical industry, battery manufacturing, glass and other fields. Battery-grade lithium fluoride (LiF) is a subdivided product of lithium fluoride. It is usually produced from lithium carbonate and lithium hydroxide monohydrate. It has the advantages of green environmental protection and good chemical stability, and can be used to produce lithium-ion battery electrolytes. .

Ion exchange production method, direct synthesis method, extraction method, metathesis method, etc. are the main preparation methods of battery-grade lithium fluoride. The ion exchange production method has the advantages of low production cost, green environmental protection, etc., and is the mainstream preparation method of battery-grade lithium fluoride. According to different raw materials, it can be subdivided into two types: lithium salt dissolution method and hydrochloric acid neutralization method; the direct synthesis method production process is relatively simple It is simple, but the quality of the finished product is poor and large-scale production has not yet been achieved; the extraction method has environmental pollution problems and is currently rarely used; the metathesis method has relatively high production costs and many by-products.

The main raw materials of battery-grade lithium fluoride are lithium carbonate and lithium hydroxide. In recent years, benefiting from the growth in downstream demand, the development speed of my country’s lithium industry has continued to accelerate. According to statistics from the Lithium Branch of the China Nonferrous Metals Industry Association, my country’s lithium carbonate production will reach 395,000 tons in 2022, a year-on-year increase of 32.5%; lithium hydroxide production will reach 246,000 tons, a year-on-year increase of 29.5%. The sufficient supply of raw materials provides favorable conditions for the development of my country’s battery-grade lithium fluoride industry.

According to the “2023 Global and Chinese Battery Grade Lithium Fluoride (LiF) Industry In-depth Research Report released by the Industrial Research Center, In terms of application fields, lithium-ion batteries are the largest demand end for battery-grade lithium fluoride, which can be used to prepare electrolyte lithium hexafluorophosphate. my country is the world’s largest producer of lithium hexafluorophosphate, and its output has maintained a long-term growth trend. In 2022, my country’s lithium hexafluorophosphate output will reach 117,000 tons, a year-on-year increase of nearly 100%. In recent years, with the accelerated development of new energy vehicles, new energy storage and other industries, my country’s market demand for lithium hexafluorophosphate has been growing. With battery-grade lithium fluoride as its core raw material, the industry’s development space has been further expanded.

There are many battery-grade lithium fluoride manufacturers in my country, and the market competition is fierce. Representative companies include China Mining Resources, Shenzhen Xinxing, Ganfeng Lithium Industry, Polyfluoropolymer, Dongpeng New Materials, etc. Sinomine Resources focuses on the research and development, production and sales of battery-grade lithium salts. It has an annual production capacity of battery-grade lithium fluoride of 6,000 tons. Currently, the company has reached a cooperation with Japan’s Morita Chemical to supply products in batches.

Industry analysts said that battery-grade lithium fluoride has broad application prospects in the field of lithium-ion batteries. In the future, as the development of downstream industries accelerates , its market space will be further expanded. my country is a major producer of battery-grade lithium fluoride. Benefiting from the sufficient supply of raw materials and the improvement of the technological maturity of local companies, the production and quality of battery-grade lithium fluoride in my country have continued to improve, and the products have been exported to many overseas countries.
