The invention provides a preparation method of a lithium difluorobisoxalate phosphate solution, and the method comprises the following steps: 1) reacting N-hydroxysuccinimide and oxalyl chloride in anon-aqueous solvent to obtain a di (N-succinimido) oxalic acid solution; and 2) adding lithium hexafluorophosphate into the di (N-succinimido) oxalic acid solution, and reacting to obtain the lithiumdifluorobisoxalate phosphate solution. According to the preparation method, the obtained solution can be directly used for lithium salt electrolyte materials of lithium ion batteries without further purification, and the method has the advantages of cheap and easily available reaction raw materials, simple operation, environmental friendliness of byproducts, and suitability for industrial production.
