Lithium-sulfur batteries (LSBs) with high energy density and low cost have been recognized as one of the most promising next-generation energy storage systems. Although it has taken decades of development, the practical application of LSBs has been hindered by several inherent obstacles, particularly the severe shuttle effect and sluggish reaction kinetics in the sulfur cathode. Various strategies have been proposed to address these problems via rational design of electrode materials and configurations. Freestanding sulfur cathode could be a promising strategy to improve the sulfur mass loading at the cathode level and energy density of LSBs. This minireview will briefly summary the recent advances in freestanding cathodes for LSBs. The advantages and disadvantages of various freestanding cathodes are discussed and the prospects for the development of flexible cathodes are envisioned.
具有高能量密度和低成本的锂硫电池（LSB）已被公认为最有前途的下一代储能系统之一。尽管经过了数十年的发展，但锂硫电池的实际应用仍受到一些固有障碍的阻碍，特别是硫阴极中严重的穿梭效应和缓慢的反应动力学。人们已经提出了各种策略，通过合理设计电极材料和结构来解决这些问题。独立式硫阴极可能是一种有前途的策略，可以提高阴极水平的硫质量负载和锂硫电池的能量密度。本综述将简要总结锂硫电池独立式阴极的最新进展。讨论了各种独立式阴极的优缺点，并展望了柔性阴极的发展前景。
