Abstract
A method of manufacturing an organic electrolyte electrochemical cell comprising at least one electrochemical couple made up of two electrodes sandwiching a solid film of porous polymer containing the electrolyte, each electrode comprising a porous layer containing an electrochemically active material and a binder, the method comprising the steps of: a polymer is put into solution in a solvent and the solution is spread in the form of a film on a support; the film of solution is immersed in a volatile non-solvent that is miscible with the solvent in order to precipitate the polymer and the polymer film is dried to eliminate the non-solvent; and the couple made up of the polymer film placed between the electrodes and in contact therewith, and impregnated with the electrolyte, is compressed while being heated to a temperature less than or equal to the temperature at which the polymer film starts to melt so as to obtain incomplete melting of the polymer, the electrodes becoming unseparable after cooling.
