摘　　要：随着可卷曲、可折叠、可穿戴及植入式柔性电子设备的出现,柔性自支撑电极材料的研究也备受瞩目。碳布是一种商用机织物,由于其高导电性、多孔网络、大表面积、良好的机械柔韧性和强度,被认为是构建柔性电极的优秀基材。近年来,各种活性物质(如金属单质、金属化合物及其复合物)直接生长或涂敷在碳布表面,当用作锂/钠离子电池负极时,它们表现出优异的机械稳定性和电化学性能。本文综述了这几类碳布基自支撑锂/钠离子电池负极材料的研究现状,重点介绍了碳布基自支撑锂/钠离子电池负极材料中的三个关键问题,具体包括碳布的预活化、活性物质在碳布上的负载形貌及电化学性能的表征,并展望了碳布基自支撑锂/钠离子电池负极材料所面临的挑战和机遇,这对于碳布用作锂/钠离子电池自支撑电极材料基底的研究具有一定的指导意义。With the surging interest in flexible electronics,such as rollable display,wearable devices,and implantable biomedical products,there is a recent concerted research effort in the development of flexible electrode materials for flexible energy storage devices.Carbon cloth is a commercially available woven fabric that has been regarded as a robust substrate for the construction of flexible electrodes due to its numerous advantages,e.g.,high electrical conductivity,porous network,large surface area,good flexibility,and robust mechanical strength.Recently,various active materials,e.g.,metal,metal compounds and composite,have been grown directly or coated onto the surface of carbon cloth.When used as the anode of lithium/sodium ion batteries,they exhibit excellent mechanical stability and electrochemical performance.This review summarizes the recent development of carbon cloth-based flexible lithium/sodium-ion battery electrodes.In particular,the prefunctionalization of carbon cloth,surface morphology of flexible electrodes and electrochemical characterization will be discussed.Finally,we will discuss the current challenges and proposed perspectives in the development of carbon cloth-based flexible electrodes.It is expected that this review could help to stimulate the further development of advanced flexible lithium/sodium-ion batteries.
