Abstract
The present invention concerns an electrode for an electric cell or supercapacitor containing a non-aqueous liquid electrolyte, the electrode comprising an electronically conducting porous first layer including at least one first face covered with a microporous second layer constituted by a polymeric material, the electrode being characterized in that said second layer is produced by coagulation of said polymer from a solution of said polymer impregnating said first face.
