摘　　要：硅基负极以其卓越的理论比容量在锂离子电池领域展现出巨大潜力。然而,体积膨胀、颗粒破碎、固态电解质界面层(SEI)不稳定以及低电导率等问题限制了其商业化应用。匹配导电聚合物粘结剂可以兼顾容纳硅基负极剧烈体积膨胀和提供电子连接通路,被视为提升硅基负极性能的有效策略。本综述系统总结了导电聚合物粘结剂在硅基负极中的应用进展,并深入探讨了聚茐类、聚噻吩类、聚苯胺类和聚芘类导电聚合物粘结剂的最新研究动态。此外,本文评估了这四种主要导电聚合物粘结剂对硅基负极性能的影响。Silicon-based anodes exhibit significant potential in the realm of lithium-ion batteries due to their remarkable theoretical specific capacity.Nevertheless,challenges such as volume expansion,particle fracture,instability of the solid electrolyte interface(SEI)layer,and low conductivity impede their commercialization.The utilization of conductive polymer binders,which can accommodate the substantial volume expansion of silicon-based anodes while facilitating electron transport pathways,is regarded as an effective strategy for enhancing the performance of these anodes.This review systematically summarizes the advancements in conductive polymer binders for silicon-based anodes and thoroughly examines the latest research developments concerning polyacrylate,polythiophene,polyaniline,and poly(pyrene)conductive polymer binders.Furthermore,this paper assesses the influence of these four primary conductive polymers on the performance of silicon-based anodes.
