Abstract: During repeated cycling of alkaline manganese dioxide cells, it is critical to ensure that adequate barrier protection is formed and maintained between the anode and cathode of the cell to prevent shorts from occurring between the cathode and anode. However, the potential also exists for anodic zinc to migrate via the absorbent separator and create a short path to the cathode. To prevent this, cells are fabricated wherein a separator is placed into the cells, a hot melt material is metered into the cell so that the hot melted material flows under the bottom edge of the separator, which is then pushed down and seated in the hot melt material as it cools. The end result is a barrier which is forms at the bottom of the cell and at both sides of the separator and virtually eliminates shorts from developing between the electrodes.
