Abstract:
A supercapacitor that combines:a casing capable of liquid-tight confinement of a liquid electrolyte; a liquid electrolyte confined by said casing; a porous composite electrode permeated by said liquid electrolyte and which is composed of a first electrode-making material and a second electrode-making material in mutual adhesion, provided that said first and second electrode-making materials are so selected that, during a period of charging said supercapacitor, said first electrode-making material functions to procure a greater extent of electrical double-layer capacitance than said second electrode-making material is capable of procuring, and said second electrode-making material procures a greater extent of pseudo-capacitance than said first electrode-making material is capable of procuring; a counter electrode that is capable of use to add or subtract electrons on said counter electrode without providing sites for reversible redox reactions that involve deposition of substances, and that is separated from said porous composite electrode by a region occupied by said liquid electrolyte; means for applying a magnetic field to said porous composite electrode and to said liquid electrolyte; and, terminals respectively in connection with said counter electrode and said porous composite electrode.
