Abstract: Power batteries have significant influence on the development of electric vehicles.Lithium ion batteries are regarded as the most promising candidate among different electrochemical energy storage devices due to their outstanding characteristics. Cycling performances and safety issues of lithium ion batteries are highly concerned and tightly related to the properties of electrolytes. State-of-the-art electrolytes are composed of organic solvents, lithium salts,and additives, and among which the additive plays an important role and shows great influence on the electrochemical performances and cycle life of the batteries. This paper reviews the recent progress on electrolyte additives, especially the ones related to high-voltage cathode and silicon-carbon anode materials. The functionalities and mechanisms of typical additives are presented in details. We believe that high performance power batteries could be realized by developing novel multi-functional electrolyte additives.

Key words: lithium-ion battery, electrolyte, additive, solid electrolyte interphase
