Wire-Shaped lithium sulfur batteries are regarded as a promising solution for burgeoning wearable electronics, intelligent textiles, flexible electronics, due to its great advantages of high theoretical specific capacity and energy density, flexibility and weavability. However, there remains a critical challenge in the manufacturing of mechanically robust, highly conductive and industrially processable fibrous cathodes. Here, a new and general strategy is proposed to produce freestanding sulfur-containing fibrous electrodes using industrially weavable stainless steel fibers (SSFs) as supports and current collectors. The SSFs based electrodes not only enable the feasibility of continuous processing and large-scale production, but also feature a porous fibrous structure that allows the imbibition of graphene-sulfur composite by facile capillary action. The wire-shaped lithium sulfur battery fabricated by this hybrid fibrous cathode shows mechanical robustness, high flexibility and excellent electrochemical performances. It can reach a capacity of 335 mAh g(-1) at a current density of 167.5 (0.1 C) mA g(-1), keep high stability after running for 100 cycles and realize a series of sophisticated applications for the flexible and wearable electronics.
