TECHNOLOGY FOCUS - ELECTRONICS - Preferred Battery: The thin profile battery has the metal surface and comprises an outer nickel clad stainless steel surface(A) over which (A1)/(A2) is received. The battery is a button type battery having a terminal housing member comprising (A). The substrate comprises conductive printed thick film ink over which (A1)/(A2) is received. At least one of the electronic component comprises a nickel containing metal surface over which the composition is received. The conductive paths comprise conductive printed thick film ink over the second portion of which the conductive adhesive mass is received. Preferred Circuit: At least one of the first and second electric components comprises a nickel containing metal surface over which the conductive adhesive mass is received.    TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Method: (M1) Involves: interposing the curable epoxy composition between the thin profile battery and the substrate; and curing the epoxy into the electrically conductive bond electrically interconnecting the battery and the substrate. (M2) involves interposing the curable epoxy composition between first and second electrically conductive components to be electrically interconnected and curing the epoxy into an electrically conductive bond electrically interconnecting the components. In the methods, at least one of the battery and substrate and at least one of the electrically conductive components comprises a metal surface with which the curable epoxy is to electrically connect. Preferred Composition: (A1) or (A2) comprises the epoxy terminated silane (less than or equal to 2, preferably less than or equal to 1 wt.%). The epoxy terminated silane comprises a glycidoxy methoxy silane or a glycidoxyproplytrimethoxysilane. The epoxy in the curable epoxy composition of (M1) has a metal surface wetting concentration of silane to form a cured electrical interconnection having a contact resistance through the metal surface of less than or equal to 0.3 (preferably less than or equal to 0.16, especially less than or equal to 0.032) ohm-cm2. The metal surface wetting concentration of silane in the curable adhesive composition is less than or equal to 2 (preferably less than or equal to 1) wt.%. The metal surface comprises nickel over which the curable adhesive composition is received.
