ResumoElectric double-layer capacitors were fabricated using polyvinyl alcohol-containing silica gels doped with HClO4 as an electrolyte and activated carbon powders, ACP, hybridized with the silica gels as a polarizable electrode. One of the capacitors fabricated had capacitance of 44 F/(gram of total ACP in the capacitor) at room temperature. The large capacitance of the totally solid state electric double-layer capacitors fabricated is ascribed to the high proton conductivity of the gels and the homogeneous hybridization of ACP with the gels by the sol-gel process.
