Abstract
Galvanic cells of the Leclanche and zinc chloride type which employ cathode mixes having relatively high ratios of EMD to conductive material and which include a minor amount of ion exchange resin in their cathode mixes exhibit enhanced light drain service and comparable heavy drain service relative to conventional cells having lower EMD to conductive material ratios.
