Abstract
Abstract A method of forming a button-type battery terminal housing member sheet includes, a) providing an electrically conductive sheet having an exposed surface, the conductive sheet being divisible into a plurality of individual button-type battery terminal housing member regions; b) masking portions of the respective regions of the exposed sheet surface with a masking material; c) applying an uncured and flowable gasket material onto unmasked portions of the respective regions of the exposed sheet surface; d) allowing the applied uncured gasket material to at least partially cure; and e) after at least partially curing the gasket material, removing the masking material from the masked portions of the respective regions of the exposed sheet surface. The sheet is preferably utilized in formation of a plurality of button-type batteries. A plurality of discrete first terminal housing members are cut and formed from the electrically conductive sheet regions. A discrete electrically conductive second terminal housing member is provided in facing juxtaposition to one of the first terminal housing members, with an anode, cathode, separator and electrolyte positioned therebetween. The first and second terminal housing members are then crimped together into an enclosed battery housing with the gasket material being interposed between the first and second terminal housing members to provide a fluid-tight seal and to provide electrical insulation therebetween.
