基于碳/MOFs及其衍生物复合材料在锂硫电池阴极中的应用OA北大核心CSTPCD

Lithium-sulfur batteries (LSBs) are considered to be one of the most promising new battery systems due to their high theoretical energy density and low price. However,there are some problems in practical application,such as poor electrical conductivity,easy volume expansion and poor cycle stability. Metal organic frameworks (MOFs) are used for LSBs due to the characteristics of large spe-cific surface area and high porosity,which can inhibit the dissolution of sulfur and improve the utili-zation rate of sulfur to achieve high cyclic stability of LSBs. Adding carbon materials with excellent electrical conductivity can improve the overall conductivity of the electrode. Therefore,the applica-tion of composite materials based on C/MOFs and their derivatives in LSBs cathodes has become a current research hotspot in LSBs. This article summarized some recent research progress on C/MOFs and their derivatives in LSBs cathode materials. The application of MOFs and their deriva-tives in LSBs electrodes was summarized and prospected.
