过渡金属硫化物在锂硫电池中的应用

Research progress in the application of metal sulfides in lithium-sulfur batteries

TMSs相比于硫具有较好导电性,同时对多硫离子有优异的吸附性,可以用来固定多硫离子,从而有效解决锂硫电池导电性较差、多硫分子"穿梭效应"、易过充等问题。系统介绍了TMSs在锂硫电池中的应用情况,主要包括应用在锂硫电池中TMSs的种类,TMSs的形貌,以及TMSs与硫的负载方法的应用研究。

Transition metal sulfides(TMSs) have a better electrical conductivity than sulfur with an excellent adsorption of polysulfide ions. They can be used to fix polysulfide ions, thereby effectively solving the poor conductivity, "shuttle effect", overcharge and other issues of lithium-sulfur batteries. This paper systematically introduces the application of TMSs in lithium-sulfur batteries, including the kinds of metallic sulfides used in lithium-sulfur batteries, the morphology of TMSs, and the loading methods of TMSs and sulfur. In addition, the application of TMSs in the modification of lithium-sulfur battery separator is also introduced in detail.
