摘 要：With the emergence and development of wearable devices,the novel ene rgy storage systems with flexible feature and high energy density are urgently needed.As we all know,for next generation high energystorage systems,lithium-sulfur（Li-S） batteries with a high theoretical capacity are regarded as one of the most promising candidates.In addition,the flexible Li-S batteries have received more and more attention.The determined factor in the flexible Li-S batteries is how to design the foldable electrodes including both anode and cathode.As for the flexible sulfur cathode,it could be obtained by integrating the electroactive sulfur with a flexible substrate,generally.In recent years,the flexible cathode of Li-S batteries have made considerable progress,however there are also many huge challenges needing to overcome,such as low content of sulfur,fast decrease of capacity and short cycle life.In this paper,the current develop status of flexible cathodes of Li-S batteries have been summarized,and the future trend also be pointed out.
