Towards the development of high-performance electric double-layer capacitors (EDLCs), new electrode materials were synthesized by using zeolite as a template. By introducing very large amount of carbon into the zelite nanochannels, very unique nanocarbon having a fullerene-like framework was successfully synthesized. By using zeolite membrane as a template, a continuous film consisting of nanoporous carbon was formed directly on a current collector film. The porous carbon membrane thus prepared is free from polymer binders, and exhibited very fast charge/discharge property. Moreover, the edge site of the nanocarbon was functionalized by quinone-type functional groups. The quinone-doped carbons showed ultra-high capacitance up to 500 F/g, and sufficient rate capability and cyclability.

为了开发高性能的双电层电容器，以沸石分子筛为模板合成了新型电极材料。通过在沸石纳米通道中引入大量的碳，成功地合成了具有富勒烯样骨架的非常独特的纳米碳。通过使用沸石膜作为模板，直接在集流体膜上形成由纳米多孔碳组成的连续膜。由此制备的多孔碳膜不含聚合物粘合剂，并表现出非常快的充电/放电性能。此外，纳米碳的边缘位置被醌类官能团官能化。醌掺杂的碳显示出高达500 F/g的超高电容，以及足够的倍率性能和循环性能。
