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 10and 10Pascal, at extrusion temperatures, in a range of frequencies of between 0.01 and 100 Hz.

High-load rate supercapacitor electrode and method for obtaining same by extrusion

The invention concerns a method for making a porous substrate-electrode complex () with load rate not less than 80% for a supercapacitor including at least the following steps: preparing a mixture containing at least one polymer (), at least one liquid pore-forming plasticizer (), and at least one active filler (); 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 () and generate porosity in the electrode. The invention also concerns an electrode paste and a collector-electrode complex.
