主　　题：Ion association Lithium metal Electrolyte additive 

摘      要：Electrolyte additives play an important role in suppressing lithium dendrites through tailoring the composition/property of the SEI,however lacking of additives can achieve high performances both in ether and carbonate electrolytes hinders further enhancement of the high voltage lithium^-metal ***,lithium perchlorate(LiClO4)has been presented as an excellent additive to meet the above *** optimized chemical composition of SEI can be achieved through the formation of ionic *** results indicate that the LiClO4 behaves like a catalyst,which promotes LiTFSI to form a better SEI to inhibit further *** coulombic efficiencies and cycling performances were obtained both in ether and carbonate *** study paves a new pathway for designing bi-soluble additives for safe lithium metal batteries.
