Abstract

A secondary zinc electrode, for example, for a nickel/zinc cell has an electrically conductive support onto each major surface of which is pressed an active zinc material. A grid structure defining a plurality of compartments is pressed into the material on each major surface of the support so as to separate the active material into a plurality of physically separate areas. Such an arrangement mitigates the shape change problem to which secondary zinc electrodes are prone in service.
