Abstract
A multi-plate wound cell assembly constructed similar to a conventional jellyroll electrode assembly except that each electrode comprises a series of plates spaced along a continuous current collector, and the plates are flat-folded rather than wound into a cylinder, is described. The length of the current collector between adjacent plates of the anode and cathode electrodes increases as the folding progresses to allow for the increase as the electrode assembly is flat-folded.
