Abstract
A method for manufacturing electrochemical cells having a low electrochemical surface, from standard electrodes used in cells having a high electrochemical surface, includes configuring the standard electrodes by folding one or more of the standard electrodes to reduce the overall length, and hence the electrochemical surface area to a fraction of that of the unfolded standard electrode. A cell stack is assembled by placing the folded electrode and a standard electrode, or alternatively a folded cathode and a folded anode, in a face-to-face relationship with a separator therebetween.
