Abstract

A method for synthesizing a purified lithium (Li)anion binding agent (ABA-F)salt and the corresponding Li(ABA-F)are disclosed. The method includes dissolving a boron-based acid in a polar solvent to form a solution. The solution is refluxed to form an anion binding agent. A stoichiometric amount of a small fluorinated salt, such as LiF, is added to the anion binding agent to form a mixture. The mixture is subsequently crystallized to obtain a substantially pure Li(ABA-F)salt. Example purified Li(ABA-F)salts include Ox-Li(ABA-F), m-Li(ABA-F), and BF—Li(ABA-F). These purified Li(ABA-F)salts provide the benefits of increased battery thermal safety without loss of electrochemical performance.
