| Research Abstract |
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.
