摘要: 锂硫电池作为锂金属电池的一种，具有理论比容量和能量密度高、硫价格低廉、环境友好等优点，是最有前景的下一代高容量存储体系之一。但是，硫正极存在多硫化物的穿梭效应的问题，容易导致硫活性物质丧失、容量衰退迅速、循环性能不好等，严重地阻碍了其商业化应用。高分子聚合物材料在结构上具有复杂性、多样性和高度可调性，可以根据应用需求对分子结构进行设计和合成，赋予聚合物材料不同的功能性。本文以功能聚合物在锂硫电池正极中的应用为研究对象，对聚合物硫正极材料以及锂硫电池用聚合物粘结剂的相关研究进展进行了总结。
Abstract: Lithium-sulfur (Li-S) battery, as a kind of lithium metal battery, is one of the most promising next-generation high-capacity energy storage systems due to its high theoretical specific capacity and energy density, low sulfur price and environmental friendliness. However, the shuttle effect of polysulfides in sulfur cathode usually leads to a series of problems such as loss of sulfur active materials, rapid capacity decline, and poor cycle life. Due to the structural complexity, diversity and high adjustability of polymer materials, we can design and synthesize molecular structure according to the application requirements to give different functionalities to polymer materials. We take the applications of functional polymers in cathode of Li-S batteries as the research object, and summarize the related research progress of polymer sulfur cathode materials and polymer binders for Li-S batteries.
