锂/硫电池因其高理论比容量(1 672 mA·h/g)、高能量密度(2 600 W·h/kg)、低成本和环境友好等优点,被认为是电化学领域最有发展前景的储能电源之一;但"穿梭效应"导致的活性物质失活和电极极化等问题阻碍了锂/硫电池的商业化应用.综述了近年来锂/硫电池电解液体系和半固态及全固态电解质的最新研究进展,并对锂/硫电池电解液未来的研发方向进行了展望;其中,液体电解液由于离子电导率高,在电池加工过程中灌装比较方便快捷,将率先工业化;而半固态和全固态电解质由于安全性能高,是未来锂/硫电池发展的主要方向.
New development of electrolytes for lithium-sulfur batteries
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.
