Abstract
An electrical feedthrough apparatus, for an electrochemical cell, is formed by a method that includes forming a feedthrough subassembly by providing a ferrule having an exterior surface and an interior opening about a longitudinal axis therethrough. The interior opening extends along the longitudinal axis of the ferrule from a first end of the ferrule to a second end of the ferrule. An electrical conductor is glassed in the opening of the ferrule. A locating member is positioned onto the ferrule in contact with the exterior surface of the ferrule in proximity to the first end of the ferrule and the locating member has a length extending beyond the second end of the ferrule. The feedthrough subassembly is then located at a position in a mold using the locating member and held in the position with the use of the locating member while insulating material is injected into the mold.
