沸石模板碳是一个有前途的候选人作为电极材料，用于构建具有高功率和高能量密度的双电层电容器，由于其三维排列和相互连接的1.2-nm纳米孔。这种碳在有机电解质溶液中表现出非常高的重量（140-190 F g（-1））和体积（75-83 F cm（-3））电容。此外，即使在高达20 A g（-1）的非常高的电流下，也可以很好地保持这样的高电容。这种非凡的高性能归功于独特的孔隙结构。
Zeolite-templated carbon is a promising candidate as an electrode material for constructing an electric double layer capacitor with both high-power and high-energy densities, due to its three-dimensionally arrayed and mutually connected 1.2-nm nanopores. This carbon exhibits both very high gravimetric (140-190 F g(-1)) and volumetric (75-83 F cm(-3)) capacitances in an organic electrolyte solution. Moreover, such a high capacitance can be well retained even at a very high current up to 20 A g(-1). This extraordinary high performance is attributed to the unique pore structure.
