To overcome the problems existing in the preparation of lithium tetrafluoroborate using the current aqueous solution method, this invention provides a method for preparing battery-grade lithium tetrafluoroborate and a lithium-ion battery. The preparation method includes the following steps: adding and dispersing boric acid and lithium salt in an alcohol solvent, while simultaneously adding hydrofluoric acid dropwise to react and obtain a reaction solution containing lithium tetrafluoroborate. The reaction solution is then subjected to azeotropic removal of water using the alcohol solvent to obtain crude lithium tetrafluoroborate. The crude product is then purified by removing the alcohol solvent to obtain battery-grade lithium tetrafluoroborate.
