Cell structure for electrochemical device and method of making same
Patent
·
OSTI ID:6410373
An electrochemical device is described, comprising the combination of housing means, positive and negative terminals exposed separately on the housing means, a plurality of cell means enclosed in the housing means and each having a pair of generally planar current collectors and a cell membrane cooperatively sandwiched therebetween, and means operably connecting the current collectors electrically to the terminals; each cell membrane being a laminate structure comprised of positive and negative electrodes and separator/electrolyte means interposed therebetween, and the positive and negative electrodes being alternatively arranged whereby each respectively is electrically common with only one of the paired current collectors; and the positive and negative electrodes having surface configurations generally opposing one another and extended in directions primarily transverse to the paired current collectors, and the interposed separator/electrolyte means having a serpentine configuration generally elongated in the direction transverse to the paired current collectors, thereby providing an interfacial area between the adjacent positive and negative electrodes greater than the area of either adjacent current collector by a minimum enhanced area ratio of 2.
