ABSTRACT:
A container for a battery and a method for manufacturing such a container are provided. The container includes a housing; a cover adapted for attachment to the housing by crimping; and a gasket crimped to the cover and housing. One or more grooves are formed in the housing or cover or both. During assembly, the gasket is positioned between the cover and the housing, and a portion of the cover and a portion of the housing are crimped together causing the gasket to flow into and conform to the shape of the grooves. Placement of the gasket within the grooves increases the surface area of the resultant seal thereby improving the seal quality without significantly increasing the thickness of the battery or cell. In addition the grooves prevent the gasket from flowing out of the crimped seam and help to maintain the crimp pressure throughout the lifetime of the battery.
