锂硫电池硫基碳正极材料的研究进展
Research progress of sulfur-based carbon cathode materials in lithium-sulfur batteries
摘要
Abstract
The carbonaceous material used in lithium-sulfur batteries has excellent mechanical, electrical,thermal conductivity, adj ustable pore structure, and rich surface properties, can effectively limit the dissolution of polysulfides to improve the electrochemical performance of lithium-sulfur batteries.In this paper, the research progress of sulfur-sulfur carbon-based composite cathode materials is reviewed from three aspects:one-dimensional carbon, two-dimensional carbon and three-dimensional carbon.The preparation method and structure design of modified sulfur-based carbon cathode materials are discussed.The results show that the porous nano-carbon with high specific surface area and high pore volume is very important to improve the electrochemical performance of lithium-sulfur battery, and the ordered mesoporous carbon composites doped with metal sulfide are proposed as lithium-sulfur.The cathode material can promote the migration of lithium ions between positive and negative electrodes, improve the cycle stability of lithium-sulfur batteries and active material utilization.关键词
