Abstract: An environmentally responsible and non-toxic alkaline cell, both catalytically and electrically rechargable, consisting of one or more iron anodes, as well as a zinc cathode, all immersed in an aquaous solution of potassium hydroxide in a plastic container. The cathodic material is cast zinc and is preferably wrapped in a special sheet of studded rubber provided with either a semi-perforated edge or a specially serrated edge on both sides to permit ionic communication between anodes and cathode. This rubber sheet should also be equipped with diagonal grooves on at least one side of the material. The anodes consist of thin, mild steel stampings, made to a special pattern, and are preferably blued to resist rust. The tips of these anodes are then coated with a paste prepared from one part 100 mesh iron powder to one part 100 mesh activated carbon powder. To form the paste, the powders are first thoroughly mixed dry and then properly wetted with distilled water.
