“…The SEI of this structure inhibits the transport of the solvent, so the derivatization reaction at the anode interface in the battery is reduced, and the battery performance can be greatly stabilized by this artificial SEI l. In addition, it can extend the cycle life of Li metal batteries. Lee et al 297 used a "dual-phase" separator to produce a lifi-rich artificial solid electrolyte interfacial layer on the Li anode surface by coating polyvinylidene fluoridehexafluoropropylene (PVDF-HFP) on a cellulose separator. Then the symmetrical electrolyzer test shows that the two-phase separator can prolong the cycle life by more than 300 h. Wen et al 298 employed a polysulfone (PSf) film with high stiffness and a cavity-free volume of about 0.3 nm to provide a stable artificial SEI on the anode surface.…”

At present, the basic structure and mechanism of solid electrolyte interface (SEI) have been studied based on different models. Although many researchers have observed the characteristics and properties of SEI through various characterization methods, it is still unable to explain its dynamic mechanism of action from the very small microscopic level. Among them, most researchers change the electrochemical performance of batteries by adding additives or material coating. Traditional research methods only state the performance of batteries from the appearance but lack detailed analysis of the electrochemical reaction of batteries during the research process. Based on the analysis of some models established by SEI, this study summarized the analysis of the research angle of SEI film through various characterization methods. The present traditional SEI and artificial SEI are introduced. Finally, the methods to improve the chemical performance of lithium battery and the challenges to solve the problems are summarized and prospected.
