ABSTRACT:
In an electrochemical cell consisting of a superposition by lamination of positive and negative electrodes, a solid polymer electrolyte as well as a metallic collector in which the negative electrode and collector layers are slightly offset with respect to each other so as to permit lateral current collection, a band of insulating material is inserted so as to prevent the free edge of the collector facing the layer of electrolyte and/or the negative electrode layer from cutting through the electrolyte layer and/or thereby short-circuiting the two electrodes. The disclosure also describes the preparation of such an electrochemical cell.
