  1. In recent years, due to the rapid development of smart devices such as mobile phones and tablet computers, the market share of small lithium batteries has grown rapidly. In addition, the technology of electric vehicles has become increasingly perfect, and the market demand for large lithium batteries has gradually released.
  2. Li difluorophosphate  is expected that in the next few years, lithium batteries will maintain Chemicalbook growth trend. Lithium batteries are mostly secondary batteries, and their poor stability, low temperature resistance, and poor cycle characteristics are the main technical difficulties for their rapid development. Studies have shown that lithium difluorophosphate as an electrolyte can effectively improve the above shortcomings of lithium batteries
Chemical Properties:

Crystalline Solid

  1. Li difluorophosphate the temperature of the reactor is lowered to room temperature, the insoluble matter is removed by filtration after depressurization, and a light yellow transparent filtrate is obtained.
  2. The solvent is distilled off under reduced pressure, and the remaining solid is used The freshly dried acetonitrile is recrystallized at low temperature and filtered to obtain crystals. After vacuum drying at 40°C, LiPO2F2 is obtained as a white powder solid. The moisture content is less than 10ppm, the color is less than 20, LiF% is less than 0.02%, and the purity is 99.7%.


  1. In a sealed stainless steel reactor, P2O5, LiF and dry tetrachlorofuran were added to the reactor at room temperature, sealed and stirred, cooled to -40°C, and replaced with nitrogen, argon or helium with a water content of less than 1ppm The atmosphere in the kettle is three times.
  2. After the water content in the kettle is less than 1ppm, the temperature is raised to 100°C, the pressure is increased to 0.8MPa, and POF3 is introduced, and the reaction temperature is 100°C and the reaction pressure is 0.8MPa; P0F3 The molar ratio with  P2O5 and LiF is 1:1.2:1.7;
