ABSTRACT:
An anode structure for a metal air electrochemical cell is provided. The structure includes a plurality of compartments, which are at least partially isolated from one another. A metal air cell using the anode structure includes the anode structure having one or more of the compartments partially filled with anode material, a cathode in ionic communication with the anode material, and a separator electrically isolating the cathode and the anode material. The volume of anode material included in the one or more compartments is preferably based on the expected expansion of the anode material.
