A Mini Review on the Interfacial Compatibility of Propylene Carbonate Based Electrolyte with Electrodes: Origine, Characterization, Development and Theoretical Calculation

Abstract

The compatibility of electrolyte and electrode has always been a key in the filed of rechargeable batteries issue because the electrolyte/electrode interface is the main site where the reaction takes place. In particular, the electrolyte with a conventional concentration consisting of propylene carbonate (PC) and lithium salt was incompatible with graphite anode, which as a classic problem attracted much attention of researcher in lithium-ion batteries (LIBs). In this case, we summarize the research progress of the compatibility between PC based electrolyte and graphite anode, including its origin, in situ characterization of graphite anode, properties and characterization of PC based electrolyte, the strategy for improving the compatibility between PC based electrolyte and graphite anode, and theoretical calculation. Among them, the mentioned strategy was prominently discussed, including coating graphite anode with another component, adding solid electrolyte interphase (SEI)-film additives and adjusting Li+ solvation state in the electrolyte. Moreover, the strategy for improving the compatibility between PC-based solution with graphite anode could be further extended to Lithium anode and other cathodes. In this case, this review will assist readers understand the importance of interfacial compatibility and how to reform the compatibility of PC based electrolyte and electrodes to improve the performance of LIBs.
