Metal laminate strip construction of bipolar electrode backplates

DETAILED DESCRIPTION It is therefore an object of the present invention to provide a bipolar electrode which is capable of insertion into a filter press electrolytic cell that will have a greatly simplified means of connecting the two backplates to provide a bipolar electrode capable of withstanding commercial electrochemical production at a significantly reduced manufacturing cost.
It is another object of the present invention to provide an improved method for electrically and mechanically connecting the anode and cathode backplates of a bipolar electrode wherein a good current efficiency is achieved such commercial electrochemical production would be facilitated thereby.
These and other objects of the present invention, together with the advantages thereof over existing and prior art forms which will become apparent to those skilled in the art from the detailed disclosure of the present invention as set forth hereinbelow, are accomplished by the improvements herein shown, described and claimed.
It has been found that the anode and cathode backplates of a bipolar electrode for use in a filter press electrolytic cell can be connected mechanically and electrically by placing a spaced series of metal laminate strips of identical and corresponding metallic makeup to the metallic makeup of the corresponding backplates upon one of said backplates, placing the other backplate in direct alignment on top of this space series of metal laminate strips such that the backplates present two parallel planes in spaced relation to each other, and effecting a weldment between the spaced series of metal laminate strips and each of the backplates.
One preferred embodiment of the improved method for mechanically and electrically connecting the backplates of a bipolar electrode is shown by way of example in the accompanying drawings without attempting to show all of the various forms and modifications in which the invention might be embodied; the invention being measured by the appended claims and not by the details of the specification
