摘要
超级电容器作为一种新型储能元件,以其优异的电化学特性和环境友好性,受到广泛关注。超级电容器主要分为双电层电容和法拉第赝电容,分别通过电极/电解液界面的双电层和电极表面的可逆反应储能。超级电容器同时具有较高的功率密度和能量密度,这很大程度上归功于性能优良的电极材料。超级电容器的电极材料主要包括碳材料、导电聚合物材料和金属化合物材料。本文主要概述了超级电容器的分类、原理,以及三种电极材料的性能特点和发展现状。
As a new type of energy storage component,super-capacitors have received a widespread attention due to its excellent electrochemical characteristics and environmental friendliness. Super-capacitors can be mainly divided into two types： the electrical double layer capacitors（ EDLCs） and Faraday capacitors,whose energy storage arises mainly through the electric double layer on the electrode / electrolyte interface and reversible reaction on the surface of the electrode materials. Therefore,super-capacitors have the advantages of both high power density and energy density,which is largely owing to the electrode materials with good property and performance. The electrode materials of super-capacitors mainly consist of carbon based materials,conductive polymer materials and metal compound materials. Based on the above,this paper mainly outlines the classification and principle of the super-capacitors,the performance characteristics,recent development of the three types of electrode materials.
