Abstract
The performance of alkaline cells comprising a zinc anode and manganese dioxide cathode can be improved, especially in high power application, by applying thermal insulating material to the cell casing. The thermal insulation material can be conveniently applied between the cell label and casing. The thermal insulating material significantly reduces the overall heat transfer coefficient, U,, for the cell. The insulation increases the internal temperature of the cell during discharge, resulting in better performance.
