Lithium difluorophosphate is a high-performance electrolyte material, mainly used in lithium batteries. Lithium batteries have attracted widespread attention due to their high energy density, long life and wide application prospects. Lithium difluorophosphate plays the role of ion transmission in lithium batteries, which can improve the working efficiency and safety of batteries. It has excellent electrochemical stability and thermal stability in battery positive electrode materials, which can effectively improve the battery’s cycle performance and capacity retention rate. In addition, lithium difluorophosphate LiDFP can also be used as a protective additive for lithium batteries to enhance the battery’s overcharge, over-discharge and safety performance.

Lithium difluorophosphate is also commonly used in the preparation of solid electrolyte materials. With the development of solid-state battery technology, solid electrolyte materials have become a research hotspot. Lithium difluorophosphate is widely used in the preparation of solid electrolytes due to its good ionic conductivity and mechanical properties. It can increase the ion conduction rate of solid electrolytes and improve the interfacial properties of batteries, thereby improving the comprehensive performance of solid-state batteries.

In addition, lithium difluorophosphate also plays a key role in the synthesis of battery materials. In the production process of lithium batteries, the synthesis of positive electrode materials is crucial. Lithium difluorophosphate can be used as one of the raw materials for synthesizing positive electrode materials, combined with other materials to prepare high-performance positive electrode materials, thereby improving the overall performance of lithium batteries.
