Abstract
A method is disclosed for forming a composite body which comprises bonding a moderately deformable metallic element to at least a portion of at least one major surface and to an associated portion of the edge surface of a solid ion-conductive electrolyte material element which contains mobile ions of a metal different from the metallic element. A method is disclosed for bonding a composite body to a deformable metallic casing which comprises pressing the sharp edge at the open end of the casing against the composite body while employing an inert atmosphere, elevated temperature and pressure.
Claims6
A method of bonding a composite body to a metallic element which comprises providing a composite body with opposite major surfaces and an edge surface, a solid ion-conductive electrolyte material, a surface portion of an ion-insulating material, and a deformable metallic element bonded to at least a portion of one major surface, providing a deformable metallic casing with an open end having a sharp edge, positioning the sharp edge of the open end of the casing against the deformable metallic element of the composite body, heating the composite body and casing in an inert atmosphere at temperature in the range of 300.degree. to 600.degree. C., and pressing the casing against the deformable metallic element in a range from 100 to 4,000 pounds per square inch to effect bonding between the composite body and the casing.
