Abstract:
A method for partially connecting copper foils of any given type and thickness with aluminum separators of any given alloy and thickness, as to be used in laminating multilayers, comprising the steps of:placing a copper foil panel on both sides of the aluminum separator, each copper foil panel has projected edges wherein the copper foil panels are larger than the aluminum separator so that the copper foil panels project beyond the separator on all sides and lie flat on it, and fixing the oversize/projecting copper foil panels to each other by providing a plurality of fixation points by attachment of the projected edges of one of the copper foil panels with the projected edges of the other copper foil panel in such a manner that there is a free space between the fixation points and the aluminum separator to allow the separator to expand.
