锂硫电池硫正极技术研究进展
Research progress on sulfur cathode of lithium sulfur battery
摘要
Abstract
Lithium sulfur (Li-S) battery has become a hotspot of next-generation high-performance secondary batteries in recent years, by virtue of the advantages of high energy density, low cost, favorable environmental friendliness. However, low utilization of active materials, rapid capacity decay and serious self-discharge greatly hindered its practical application. Since cathode is a key component of rechargeable battery, it is very necessary to design and construct rationally the constitution and structure of sulfur cathode for improving the cell performances. In this paper, basic principles, existent problems and solving approaches of Li-S battery were analyzed at first. Then, the research progresses on active material, current collector, coating layer, binder and additive of sulfur cathode were reviewed. Finally, the further developing prospects of the battery were discussed. It is pointed out that more attention should be paid to real energy density of sulfur cathode, and research scope of Li-S battery should not be limited to cathode material.关键词
