Abstract:
1. An electrode for an electrochemical assembly, the electrode comprising a film of porous composite product consisting of: 10 to 40% by weight of thermoplastic elastomers or polymers which are insoluble in aqueous or organic solvents, 5 to 40% by weight of polymers which are soluble in aqueous or organic solvents, the soluble polymers being selected from the group consisting of polyethers and polyalcohols, and between 30% and 90% by weight of carbonaceous inorganic fillers having a specific surface greater than 1000 m wherein the insoluble thermoplastic elastomers or polymers and the soluble polymers form a non-fibrillated polymeric material, the said film being obtained by extrusion, the porous composite product exhibiting a “BET” specific surface of greater than 10 m
