Abstract: A fixture in which an attractive magnetic force is utilized to join two parts of a container or housing together is discussed. The fixture comprises a fixture body portion, a fixture base portion and a removable fixture plate portion. At least one body magnet resides within the fixture body portion and at least one plate magnet resides within the removable fixture plate. The fixture body and plate magnets are positioned such that when they are brought together, an attractive magnetic force pulls the plate towards the fixture body. Therefore, when the respective housing portions are positioned within the fixture, the magnetic force compresses the housing portions together.

Abstract: A direct welding process for joining a current collector to a terminal pin in the construction of electrochemical cells is described. The resistance welding process utilizes increased current combined with an applied force to bond dissimilar metals with a melting temperature differential of preferably more than 500° C. Preferably, the method is used to bond the terminal pin to the cathode current collector. This method of attachment is suitable for either primary or secondary cells, particularly those powering implantable biomedical devices.

Abstract: An electrochemical cell having an enclosure comprised of an enclosure body portion composed of a relatively high electrical resistivity material and an enclosure lid portion composed of a ductile material is discussed. The body portion of the enclosure preferably comprises Grade 5 or 23 titanium and the lid portion preferably comprises Grade 1 or 2 titanium. The enclosure lid is joined to the body of the enclosure through a welding process such as laser welding. The combination of these differing materials provides an enclosure that effectively retards the occurrence of eddy current induced heating as well as provides an enclosure that is more mechanically robust.
