ABSTRACT:
An improvement in electric accumulator cells having a dissoluble electrode (e.g., a zinc electrode) and a counter-electrode (e.g., nickel electrode) is disclosed. The dissoluble electrode is formed by a central layer having outer layers disposed on either plane side thereof. The outer layers are generally smaller in planar size than the central layer and preferably all of the layers are porous, perforated or netlike. The multi-layer electrode has particular utility in a cell in which the dissoluble electrode and/or separator disposed between the dissoluble electrode and counter-electrode are vibrated in the plane of the electrode. Dendrite growth and shaping of the deposited active material are substantially minimized and improved cell life is obtained.
