It is valuable to realize the flexibility of lithium-sulfur batteries, but the unavoidable shuttle effect and the inability of traditional components to withstand bending have brought challenges to related research. Herein, we assembled the bendable self-supporting cathode with carbon nanotube film-loaded sulfur and the modified PP separator with conductive composite interlayer to obtain a bendable lithium-sulfur battery. Benefiting from the charge transport facilitated by both the pore-rich network structure of the bendable substrate and the additional electronic pathways of the conductive interlayer, the assembled bendable lithium-sulfur battery displays a specific capacity as high as 1178 mAh g⁻¹ at 0.1 C and a capacity retention of 66.0 % at 1 C. In addition, the conductive composite interlayer can inhibit the shuttle effect of polysulfide through chemical adsorption and promote its conversion. Moreover, the high flexibility of each component enables the assembled lithium-sulfur battery to withstand repeated bending and exhibits excellent cycling stability (capacity retention of 73.2 % after 500 cycles at 0.5 C) at a bending angle of 150°. This work provides a highly feasible solution to construct lithium-sulfur batteries with desirable energy-storage properties and bendable performance.

实现锂硫电池的柔性是有价值的，但不可避免的穿梭效应以及传统组件无法承受弯曲的特性给相关研究带来了挑战。在此，我们将碳纳米管膜负载硫的可弯曲自支撑正极与具有导电复合中间层的改性PP隔膜组装在一起，得到可弯曲的锂硫电池。受益于可弯曲基板的富含孔隙的网络结构和导电夹层的额外电子通路促进的电荷传输，组装的可弯曲锂硫电池表现出高达1178 mAh g -1 的比^容量0.1 C时容量保持率为66.0%，1 C时容量保持率为66.0%。此外，导电复合中间层可以通过化学吸附抑制多硫化物的穿梭效应并促进其转化。此外，各部件的高柔韧性使得组装好的锂硫电池能够承受反复弯曲，并在150°弯曲角度下表现出优异的循环稳定性（0.5C下500次循环后容量保持率为73.2%）。这项工作为构建具有理想储能性能和可弯曲性能的锂硫电池提供了一种高度可行的解决方案。
