Abstract
An exemplary electrochemical cell incorporates at least a first battery electrode, such as a zinc electrode, at least a second battery electrode, such as a reversible metal electrode such as nickel, and at least an oxidant reduction electrode, such as an air cathode. The oxidant reduction electrode(s) is configured in a cell housing such that it is essentially orthogonal to the first and second electrodes. The cell housing contains electrolyte therein and the electrodes are immersed, at least partially, in the electrolyte. The positioning of the oxidant reduction electrode(s) on the side of the cell and relatively perpendicular to the first and second (metal) electrodes, allows for more consistent ionic resistance across all the metal electrodes. Optionally, a fourth or oxygen evolving electrode may be provided in the cell housing, horizontal, orthogonal, and below the first and second electrodes to provide oxygen bubbles for mixing the electrolyte.
