ABSTRACT:
An ionically permeable separator for a LeClanche cell, and methods of making and using same, are provided for in the invention. The separator comprises a Kraft paper separator and a corrosion-inhibiting coating thereupon selected to prevent corrosion of a zinc anode of the LeClanche cell. The separator may be configured for use in round or flat LeClanche cells. The separators of the invention may be used in heavy duty batteries containing an electrolyte comprising zinc chloride as a primary component. Cells made in accordance with the invention exhibit comparable or improved capacity and other performance characteristics in respect of conventional cells.
