Abstract: An electrode paste for a supercondenser. The electrode paste is a mixture containing a polymer formed using a liquid softening agent and an active charge. The paste is in the form of gel having an elasticity module of between 104 and 108 Pascal, at extrusion temperatures, in a range of frequencies of between 0.01 and 100 Hz.

Abstract: An electrode or a supercondenser. The electrode paste is a mixture containing a polymer formed using a liquid softening agent and an active charge. The paste is in the form of gel having an elasticity module of between 104 and 108 Pascal, at extrusion temperatures, in a range of frequencies of between 0.01 and 100 Hz.

Abstract: The invention concerns a method for making a porous substrate-electrode complex (6) with load rate not less than 80% for a supercapacitor including at least the following steps: preparing a mixture containing at least one polymer (1), at least one liquid pore-forming plasticizer (3), and at least one active filler (2); extruding the mixture in paste form; depositing the paste on the substrate and laminating same; and treating the resulting complex to eliminate all or part of the plasticizer (3) and generate porosity in the electrode. The invention also concerns an electrode paste and a collector-electrode complex.
