Lithium-sulfur batteries are considered as the most promising energy storage technology in the field of electrochemistry due to their high theoretical specific capacity(1 672 mA·h/g),high energy density(2 600 W·h/kg),low cost and environmental friendliness.However,the deactivation of active substances and electrode polarization caused by the shuttle effect hinder the commercial application of lithium-sulfur batteries.This article reviews the latest research progress on liquid and solid electrolytes in lithium-sulfur battery electrolyte systems in recent years,and looks forward to the future research and development directions of lithium-sulfur battery electrolytes.In particular,liquid electrolyte will be the first to be industrialized due to its high ionic conductivity and convenient to fill during battery processing.Semi-solid and solid electrolytes are the main direction for the development of lithium/sulfur batteries in the future due to their high safety performance.
