Abstract The current status of the additives used in lithium ion battery electrolytes was reviewed. The additives were assorted into film-forming additives, conductive additives, flame-retardant additives, and multifunctional additives. Each group has been systematically discussed in terms of structural characteristics and electrochemical mechanisms. The utilizing condition and effects of some different additives were compared. The prospect of the additives used in non-aqueous electrolyte in the future was predicted.
