Research progress of negative film-forming additives in electrolyte for Li-ion batteries

As one of the main parts of Li-ion battery,electrolyte plays a key role in the improvement of battery performance.Utilization of additives is an important way to improve the electrolyte performance.Anode film forming additive is one of the necessary functional composition in electrolyte for lithium ion battery.The recent progress on research and development of negative film-forming additives from the principles or mechanisms of film formation and quantum calculation was reviewed in this paper.The problem and the possible trend in this area were proposed.
