Paragraph 0073-0075, (2020/10/04)
The invention provides a preparation method of a lithium salt compound, which comprises the following steps: adding alkylphosphite dialkyl ester into a protic solvent, uniformly mixing, and adding alkyl acrylate while stirring to react, thereby obtaining a compound A; adding an acid solution A into the compound A, carrying out a heating reflux reaction, adding acetone after the reaction is completed, and crystallizing to obtain a compound B; adding an alcoholic solution and an acid solution B into the compound B for esterification to obtain a compound C; adding an alcoholic solution into the compound C, uniformly stirring, then adding a lithium source, stirring for reaction, and concentrating and crystallizing after the reaction is finished, so as to obtain the lithium salt compound. The invention also provides a lithium ion battery electrolyte containing the lithium salt compound. The lithium salt compound prepared by the method provided by the invention has flame retardance and goodconductivity, and the lithium ion battery electrolyte composed of the lithium salt compound is stable in performance, safe and reliable.
