Abstract
A method of manufacturing a current collector for use in a capacitor (e.g., a DEL capacitor) having an aqueous or non-aqueous electrolyte, such as an aqueous sulfuric acid electrolyte. The conductive basis of the current collector is preferably, but not necessarily, comprised of lead or a lead alloy. The portion of the conductive basis that will be in contact with the electrolyte is provided with a protective layer that is created by deposition of one or more layers of one or more protective coating materials thereto. Each protective coating material is comprised of at least a conductive carbon powder and a polymer binder that is resistant to the electrolyte. Preferably, but not essentially, the protective coating material(s) are applied to the conductive basis in the form of a paste, which is subsequently subjected to a solvent evaporation step and a thermal treatment step.
