Abstract: Improved anodes comprising dendritic zinc suitable for use in electrochemical devices such as primary and secondary cells and methods for preparing the anodes are disclosed. These methods are: (1) coating a porous support with, or shaping an electrode from already-prepared zinc dendrites; (2) in situ reduction of a porous substrate coated with a zinc compound; and (3) electrodeposition of zinc dendrites from a solution of a zinc compound onto a porous support. The above methods include various washing steps which prevent side reactions between the zinc dendrites and other substances which may be present during the production and use of the anodes. Various molding and shaping steps may also be included, and in situ amalgamation, or amalgamation of the finished anodes is generally desirable. These anodes have unusually high surface area, porosity and efficiency.
