| Outline of Final Research Achievements |
Micro- and mesoporous activated carbon, which was intended for the electrode use of electrical double-layer capacitor, was developed. This activated carbon was prepared from rice husk, by leaching nano-size silica from carbonized rice husk to develop mesoporosity and by adding sugar to develop microporosity. When non-aqueous electrolyte or ionic liquid was used, the activated carbon displayed superior electricity-storage performance rather than commercial resin-derived activated carbon. Electrical impedance spectroscopy clarified a relationship between the porous structure and capacitive-resistive property of the rice husk-derived activated carbon.
