| Research Abstract |
The capacitive behavior of ruthenium oxide-based electrodes in non-aqueous imidazolium salt electrolytes has been investigated. Composite electrodes where ruthenium oxide nanoparticles are dispersed onto porous carbon provide higher specific capacitance than porous carbon electrode by including pseudo-capacitance of ruthenium oxide. Such pseudo-capacitance is indicated to be correlated with the forming ability of hydrogen bond for imidazolium ion.
