The preliminary results and recent finding on LiBOBbased electrolyte are summarized. Emphasis is placed on the electrochemistry of the BOBanion on both graphite anode and metaloxidebased cathode surfaces. Certain issues associated with the impurity and safety of the salt in lithium ion systems are also discussed. The advantages and disadvantages of LiBOB are generalized. Finally , the emphases and strategies for RD of electrolyte of improved performance i
