摘要
锂硫电池是一种传统而又新颖的化学电池,得益于硫正级的高理论容量、低成本和环境友好的特点,被认为是下一代最有潜力的储能器件。但是,现阶段的锂硫电池却受限于缓慢的转化动力学过程、由多硫化物溶解导致的“穿梭效应”而表现出实际容量低、循环性能差等问题。文章从锂硫电池中催化剂材料对多硫化物转化过程的催化作用入手,分析多硫化物溶解现象与锂硫电池性能优劣的辩证关系。
Lithium sulfur battery is a traditional and novel chemical battery.Thanks to the high theoretical capacity,low cost and environment-friendly characteristics of sulfur positive level,it is considered to be the most potential energy storage device of the next generation.However,the lithium sulfur battery at this stage is limited by the slow conversion kinetic process and the "shuttle effect" caused by polysulfide dissolution,which shows the problems of low actual capacity and poor cycle performance.This paper deeply discusses the dialectical relationship between polysulfide dissolution and the performance of lithium sulfur battery.
