摘要
Electrical feedthroughs are presented for redistributing thermally-induced stresses that result from welding. In some embodiments, an electrical feedthrough includes a tubular conduit having a flange at one end. The flange includes a first surface disposed opposite a second surface. The first surface includes at least one of a protrusion and a notch. The electrical feedthrough also includes an electrically-conductive terminal disposed through the tubular conduit. An electrically-insulating material is disposed between the tubular conduit and the electrically-conductive terminal and forms a seal therebetween. The protrusion and the notch are configured individually or as a combination to reduce thermally-induced stresses within the electrically-insulating material that result from welding the flange. Methods for welding such electrical feedthroughs to a wall, such as a wall of a battery housing, are also presented.
