摘要
目前,对能源的需求急剧增加,超级电容器作为绿色储能器件备受关注。超级电容器按储能机理可分为双电层电容器及法拉第赝电容器两种。双电层电容器的电极材料主要由炭基材料组成,法拉第赝电容器的电极材料主要由导电聚合物及金属氧化物构成;炭基材料与导电聚合物或金属氧化物等复合产生的协同作用可获得更优异的电化学性能。多孔电极材料由于其大的比表面积、独特的多孔结构、多样化的组成和优异的电子导电性而引起了广泛的关注。总结了具有微观多孔结构的超级电容器材料的制备方法以及结构-性能的关系,对比指出多孔超级电容器电极材料因其更高的比表面积和孔隙率而更有利于获得高性能超级电容器。
At present,the demand for energy has increased dramatically,and supercapacitors have attracted much attention as green energy storage devices.Supercapacitors can be divided into electric double layer capacitors and Faraday tantalum capacitors according to the energy storage mechanism.Electrode materials of the electric double layer capacitor are mainly composed of carbon-based materials,and electrode materials of the Faraday tantalum capacitor are mainly composed of conductive polymers and metal oxides.The synergistic effects of the carbon-based materials combined with the conductive polymers or metal oxides can obtain more excellent electrochemical performance.The porous electrode materials have a large specific surface area,a unique porous structure and a diverse composition,and the excellent electronic conductivity has caused extensive concern.The relationship between preparation methods and structure-performance of supercapacitor materials with microscopic porous structure were summarized.It indicated that porous supercapacitor electrode materials were more favorable for obtaining high performance supercapacitors due to their higher specific surface area and porosity.
