Abstract
An anode comprises one or more sheets of expanded zinc mesh. The thickness and mesh size of the expanded zinc mesh may vary. A single sheet of zinc mesh may be coiled, forming continuous electrical contact with itself. Alternatively, a single sheet of zinc mesh may be folded into layers, each layer in electrical contact with its adjacent layers. A third alternative is the use of two or more sheets of zinc mesh, layered on top of each other so that each layer is in electrical contact with adjacent layers. These zinc mesh anodes are combined with a casing, a cathode, an electrolyte solution, and a separator between the cathode and anode to manufacture electrochemical cells.
