Abstract
An electrode assembly constructed of continuous anode and cathode electrode that are overlaid in overlapping fashion and folded several times rather than wound into a cylinder in the conventional 'jelly roll' electrode assembly. The electrode assembly has a first side that is curved substantially along a single arc and a second side opposite the first side that is curved substantially along a plurality of arcs. The electrode assembly is designed for casings for electrochemical cells or batteries having profiles that are not well suited for the jelly roll configuration.
