Zinc electrode with reduced dendritic propagation

Microporous separators conventionally used in lead-acid accumulators are proposed to substitute rayon-type separator during discharge of zinc anode alkaline accumulators, while the same accumulator is charged mainly through rayon-type separator. Thus the positive qualities of rayon-type and microporous-type separators are amalgamated. This is achieved by new cell design and charging method. Enhanced characteristics are obtained versus the conventional setups.
