Abstract
An electrochemical cell comprising a relatively thin strip of anode material, first and second electrolyte layers coated on the opposing surfaces of the anode strip, first and second relatively thin strips of cathode material contacting the first and second electrolyte layers, thereby forming a laminate strip with the electrolyte layers and anode strip and a single cathode current conductor strip. The laminate strip is deformed such that both of the first and second strips of cathode material contact the single cathode current conductor strip along substantially the entire length thereof. In one embodiment, the cell takes the form of a spiral, in which the conductor strip is superposed to the laminate strip and the combination is rolled lengthwise, and in another embodiment, the cell takes the form of a stack in which the laminate strip is fan-folded and the conductor strip is fan-folded and inserted between the folds of the laminate strip such that the corners of the folds of the laminate strip are perpendicular to the corners of the folds of the conductor strip. s
