A bifold electrode and separator assembly is disclosed for winding into a jelly roll galvanic cell, the first generally rectangular electrode being enveloped by first and second separator sheets having a width twice that of the electrode and a length substantially that of and slightly greater than the electrode, the first sheet being folded along one elongated edge of the electrode and adhered to the two side faces thereof, and the second sheet folded along the second elongated edge of the electrode and adhered to the first sheet over the two side faces of the electrode. A terminal tab extends from the electrode through the fold of one of the sheets. A second electrode is placed on the outside, and the assembly wound into a jelly roll for placement in a cell container.
