  • INQUIRY

 Lithium difluorophosphate is an inorganic compound with the chemical formula LiPO₂F₂. This substance mainly appears as a white powdery solid, with a melting point higher than 300°C, a density of 1.979g/cm³, and a solubility of 40324mg/L at 20°C. Its vapour pressure is 0.000000145Pa at 25°C and 298K.

 Lithium difluorophosphate has a wide range of applications in the battery field, especially in the electrolyte of lithium-ion secondary batteries. It can form a film at the electrode interface, thereby improving the high and low temperature cycling performance of the battery, reducing the self-discharge of the battery, and effectively reducing the use of lithium hexafluorophosphate. In addition, lithium difluorophosphate can improve the low-temperature output characteristics of the battery, inhibit the decomposition of the cathode surface during high-temperature cycling, and prevent the oxidation reaction of the electrolyte solution, thus improving the output characteristics and dissolution characteristics of the battery after high-temperature storage.
