Plastic envelope confines active cell materials. Carbon conductive coating on the zinc anode serves as the cathode collector for the adjacent cell. Wax coating provides the battery seal. Connector strips connect the flat cell stack to the battery terminals. Lithographed steel jacket is electrically insulated from battery components.
Specialized terminals provide positive and negative external contact surfaces.
The more pure the cathode material, the better the performance. An anode of high purity zinc alloy. A highly conductive, slightly acidic, electrolyte solution of ammonium chloride and zinc chloride in water. The carbon component of the cathode is usually carbon black and provides increased conductivity and moisture retention. Typically, Zinc Chloride batteries have a higher proportion of carbon to manganese dioxide than LeClanche.
