1. An apparatus, comprising: an anode having an elongate ribbon shape;a cathode having an elongate ribbon shape having a long side and a short side, the cathode disposed adjacent to and in alignment with the anode, the cathode having at least one edge on the short side offset from a corresponding edge of the anode;a separator disposed between the anode and the cathode; andan edge film positioned at the edge on the short side of the cathode that is offset from the corresponding edge of the anode, the edge film located between and contacting both the cathode and the separator such that the edge film is positioned and configured to prevent the edge on the short side of the cathode from damaging the separator or the anode as the anode and cathode are wound together into a roll. 2. The apparatus of claim 1, further comprising adhesive means for connecting the edge film means to the cathode. 3. The apparatus of claim 2, wherein the adhesive means include a pressure sensitive adhesive. 4. The apparatus of claim 2, wherein a first adhesive interconnects the edge film means to the cathode, the first adhesive covering less than an entirety of the cathode. 5.
