Research status of solid electrolyte interface of anode in lithium ion batteries

The progress on additives of interphase films formed in anode/electrolyte interphases for lithium ion batteries was reviewed.On the basis of summarization of the characterization and mechanism of SEI film formation on anode surface,the possible effect factors on the SEI film were given.The safety performance,such as thermal stability and reversibility were highly dependent on the quality of the SEI.
