A model cathode for mechanistic study of organosulfide electrochemistry in Li-organosulfide batteries
文献摘要：
Organosulfides offer new opportunities for high performance lithium-sulfur(Li-S)batteries because of materials abundance,versatile structures and unique properties.Yet,their redox kinetics as well as cycling performance need to be further improved.Employing redox mediators is a highly effective strat-egy to address above challenges.However,the underlying mechanism in this chemistry is so far insuffi-ciently explored.Here,phenyl disulfide(PhS-SPh)and phenyl diselenide(PhSe-SePh)are used as a model system for mechanistic understanding of organosulfide electrochemistry,particularly the rate acceleration.Profiling the reaction thermodynamics and charge-discharge process reveals redox of both S-S and C-S bonds,as well as that the coupling between radical exchange and electrochemical redox is the key to enhance the sulfur kinetics.This study not only establishes a basic understanding of orgaon-sulfide electrochemistry in Li-S batteries,but also points out a general strategy for enhancing the kinetics of sulfur electrodes in electrochemical devices.
