As the electrol d e solution, concentrated acidic, or alkaline media, for example, H2SO4, KOH solution, are often utilized for the carbon and ruthenium dioxide supercapacitor because ofthe superior ionic conductivity. Manganese dioxides are, however, soluble in the acidic... [Pg.328]

Metal-oxide-based supercapacitors are characterized by a chemical reaction at the surface of the electrodes. This causes a charge transfer (pseudo-capacitance). The most widely-used metal oxide is ruthenium dioxide (RUO2). This technology uses H2SO4 as the electrolyte and presents a very low internal resistance. However, the very high cost of metal oxides restricts their use to mihtary or space apphcations. [Pg.211]
