Lithium-sulphur batteries (LiSBs) have garnered significant attention as the next-generation energy storage device because of their high theoretical energy density, low cost, and environmental friendliness. However, the undesirable "shuttle effect" by lithium polysulphides (LPSs) severely inhibits their practical application. To alleviate the shuttle effect, conductive polymers have been used to fabricate LiSBs owing to their improved electrically conducting pathways, flexible mechanical properties, and high affinity to LPSs, which allow the shuttle effect to be controlled. In this study, the applications of various conductive polymers prepared via the simple yet sophisticated electropolymerisation (EP) technology are systematically investigated based on the main components of LiSBs (cathodes, anodes, separators, and electrolytes). Finally, the potential application of EP technology in next-generation batteries is comprehensively discussed.
锂硫电池（LiSBs）因其高理论能量密度、低成本和环境友好性，作为下一代储能装置受到了广泛关注。然而，多硫化锂（LPSs）产生的不良“穿梭效应”严重阻碍了它们的实际应用。为了减轻穿梭效应，导电聚合物因其改善的导电通路、灵活的机械性能以及对LPSs的高亲和力而被用于制造锂硫电池，这使得穿梭效应得以控制。在本研究中，基于锂硫电池的主要组成部分（阴极、阳极、隔膜和电解质），系统地研究了通过简单而精密的电聚合（EP）技术制备的各种导电聚合物的应用。最后，全面讨论了电聚合技术在下一代电池中的潜在应用。
