摘　　要：锂硫电池作为新一代二次电池拥有超高的理论能量密度,为解决其穿梭效应引起的容量快速衰减的问题,通过在隔膜上修饰一层功能性的中间层来抑制穿梭效应是简单而行之有效的方法,本文研究了羟基化纳米多孔碳中间层材料及其构效关系,实验得出使用孔径为100 nm的羟基化多孔碳材料NPC-100能够有效的抑制穿梭效应,提升电池循环性能。Lithium-sulfur batteries have a very high theoretical energy density as a new generation of secondary batteries. In order to solve the problem of rapid capacity decay caused by its shuttle effect, it is simple and effective method to suppress the shuttle effect by modifying a functional interlayer on the separator. This paper researched the hydroxylated nanoporous carbon interlayer material and its structure-activity relationship. Experiments have shown that the use of a hydroxylated porous carbon material NPC-100 with a pore size of 100 nm can effectively inhibit the shuttle effect and improve the cycle performance of the battery.
