Provided herein are a battery cell of a battery pack to power electric vehicles. The battery cell can include a housing. The housing can define an inner region. An electrolyte can be disposed in the inner region defined by the housing. The battery cell can include a lid. A gasket can couple the lid with the first end of the housing to seal the battery cell. The gasket can include a first gasket surface and a second gasket surface. The first end of the housing can have a crimped edge disposed about the first gasket surface to couple the gasket with the first end of the housing and position the second gasket surface adjacent to the electrolyte. The crimped edge can have a first crimped surface having a predetermined pattern for wire bonding and a second crimped surface disposed adjacent to the first gasket surface.
