Synthetic Method of Lithium bisoxalatoborate

摘要

The present invention relates to a method for synthesizing lithium bisoxalatoborate (LiBOB), and more specifically, a polar solvent having a boiling point higher than that of water to synthesize lithium bisoxalatoborate (LiBOB) is used. It relates to a method for synthesizing lithium bisoxalatoborate (LiBOB). According to the present invention, in order to synthesize lithium bisoxalatoborate (LiBOB), a polar solvent having a boiling point higher than that of water is used as a solvent to completely remove water generated under reduced pressure during the reaction, and after cooling, impurities are filtered out to remove lithium bis When synthesizing oxalatoborate (LiBOB), there is no need to go through separate process to remove the water and unreacted substances (impurities), which can simplify the synthesis process of the compound, and low water / high purity lithium bisoxalatoborate (LiBOB) can be synthesized in high yield.
