  • Anion binding agent lithium salts for battery electrolytes
    Patent number: 11845765
    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 BF3—Li+(ABA-F)?. These purified Li+(ABA-F)? salts provide the benefits of increased battery thermal safety without loss of electrochemical performance.
