摘　　要：随着柔性电子器件的应用受到广泛关注,与之匹配的柔性电源相关研究已成为热点。锂硫电池系统具有的高理论能量密度等优势,在高性能电子设备等器件中具有广阔应用前景。而高性能柔性锂硫电池的开发更能满足未来的柔性电子设备对柔性电源的性能需求。在柔性电池中,具有机械柔性的电极是核心组件之一,需同时实现提供电子导电骨架、离子扩散通道及活性材料载体等功能。随着纳米碳、高分子、金属泡沫等材料的引入,锂硫电池柔性正极材料领域已取得众多研究进展。本文介绍了锂硫电池及其柔性正极的特性,评述了锂硫电池柔性正极材料方面的研究进展,并展望了其未来研究方向和发展空间。With the development of emerging flexible electronic devices, high performance flexible power sources have attracted great attention. Lithium sulfur battery with merits in high energy density and low cost holds promise in application in next generation flexible energy battery system. Flexible electrodes are key components in flexible batteries, which serve as electronic conductive skeleton, ion conduction skeleton, and active material hosts. In this paper, the characteristics of lithium-sulfur battery and its flexible cathode are briefly introduced, and the research progress of flexible cathode material for lithium-sulfur battery is reviewed. The future research direction and development space of lithium-sulfur battery are prospected.
