Current collector and method for production thereof

Current-collector electrodes for condensers, etc., are produced by coating a base (e.g., aluminum foil) with a porous, electrically conductive layer (e.g., of graphite or titanium) which is itself coated and preferably impregnated with a layer of polypyrrole. Production of current-collector electrodes, especially for condensers, e.g. double-layer condensers (super condensers) and electrolyte condensers, batteries or similar electrical devices, involves coating a base (e.g., metal foil such as aluminum foil) with a porous, electrically conductive layer (e.g., of graphite or titanium) which is coated, especially impregnated, with a layer of polypyrrole. An Independent claim is also included for current-collector electrodes as described and as obtained by this method.
