摘　　要：超级电容器由于能提供比电池更高的功率密度,比传统电容器更高的能量密度而备受关注。但目前其应用仍存在能量密度低的问题。碳材料、金属氧化物和导电聚合物是常见的三种超级电容器电极材料,而其中不同形式碳材料是电容器中研究和应用最广泛的电极材料。细菌纤维素是由细菌分泌产生的具有一定纳米级孔径分布的多孔生物材料,具有高强度和模量、高孔隙率、极好的尺寸和热稳定性的特性。以细菌纤维素为原料制备电极材料是近年来超级电容器领域的热点研究方向之一。本文以细菌纤维素基电极材料的种类、制备方法和性能为线索,综述了国内外细菌纤维素基超级电容器电极材料的研究进展,并归纳总结了电极材料最优的形态和制备方法,进一步对该类电极材料的发展趋势进行了展望。Supercapacitors as a new-type energy storage devices have drawn much attention because they can provide higher power density than batteries and higher energy density than traditional dielectric capacitors. But at present their application are still exist the defect of low energy density. Carbon materials, metal oxides and conductive polymers are three more commonly utilized electrode materials for supercapacitors, and the different forms of carbon materials are the most widely research and application of capacitor electrode materials. Bacterial cellulose （BC） is a porous and biological polymer which secreted by some bacterias, and BC has special properties of high mechanical strength and modulus, high porosity, good size and thermal stability. Consequently, significant research interest has been directed into the research of the carbon electrode materials which use bacterial cellulose as a raw material. In this paper, we present a review of the research progress of the BC based electrode material for supercapacitor application in term of the types of materials, preparation methods and performances. Furthermore, the optimum configuration, synthesizing method and the developing trend for the bacterial cellulose composite are summarized.
