Abstract:
A method of manufacturing an inseparable electrode couple, the method comprising the following steps:(A) (1) putting a polymer into solution in a solvent; (2) spreading said solution in the form of a film on an inert support; (3) immersing the film in a volatile non-solvent that is miscible with the solvent of step (A)(1) in order to precipitate said polymer; (4) drying the polymer film to eliminate said non-solvent; (B) impregnating the polymer film and electrodes with an organic electrolyte, (C) forming a couple by placing the impregnated polymer film between the impregnated electrodes and in contact therewith, wherein the electrodes and the polymer film are impregnated before forming the couple; (D) pressing the couple, while heating to a temperature less than or equal to the temperature at which said polymer film starts to melt so as to obtain incomplete melting of said polymer; (E) cooling the pressed and heated couple of step (D) whereby the electrodes are inseparable.
