Abstract
The performance of alkaline cells comprising a zinc anode and manganese dioxide cathode can be improved, especially in high power application, by the addition of electrically conductive powders such as tin, copper, silver, magnesium, indium or bismuth to the anode mixture. The conductive powders are in physical mixture with the zinc particles. A preferred electrically conductive powder is tin powder. The alkaline cell to which the conductive powders are added preferably contain no added mercury and preferably are also essentially free of lead.
