Electrode for a rechargeable electrochemical current source, and method of making same

Electrode for a rechargeable electrochemical current source and a method of making the same, said current source employing an electrolyte, the electrode having an electrically conductive collector and a mixture of an active mass in a plastic material distributed over the collector and sintered thereon to form an integral element. The electrode has a porous layer of material covering at least a substantial portion of its active surface, the porous layer being made of an electrically non-conductive material which is chemically inert with respect to the electrolyte, the plastic material being bonded to the porous layer by being sintered thereto.
