Abstract
An electrode assembly for use in a galvanic cell has electrodes disposed in superimposed pockets of separator material and end surfaces having a uniform appearance. Also provided is a method for producing such an electrode assembly which method is readily adaptable to high speed automated processes of manufacture.
Claims9
A galvanic cell comprising a coiled electrode assembly comprising a separator assembly having a first pocket formed by a first strip of separator material superimposed over a second strip of separator material and each separator material having an adherable edge, and a second pocket formed by a first strip of separator material, superimposed over a second strip of separator material and each separator material having an adherable edge, said second pocket being superimposed over said first pocket such that the adherable edges of said first pocket and said second pocket are aligned with at least a portion of the adherable edges adhered to form a seam functioning as a pivot for the first pocket and second pocket;
- a first electrode disposed in said first pocket;
- and a second electrode disposed in said second pocket;
- said electrode assembly coiled about an axis transverse to the adhered edges such that the seam formed by the adhered edges is in a plane which is normal to the coiling axis.
