The electrode structure includes a cathode, anode and polymeric separator, wound into an oval configuration having a length and width equal to interior dimensions of the rectangular housing. The oval shape is achieved by winding a long, flat electrode structure around a mandrel. The length of the electrode structure is chosen based upon the size of the mandrel, the interior dimensions of the housing, and the width of the electrode structure, such that, after winding, the resulting oval structure snugly fits within the rectangular housing leaving no remaining spaces, other than in corners of the housing. A leaf spring is provided between a free end of the electrode structure and an interior wall of the housing for ensuring that the electrode structure remains tightly wound. Appropriate electrical contacts are provided to the anode and cathode of the electrode structure. The housing is flooded with a non-aqueous electrolyte, sealed, then employed for powering an implantable medical device for implantation within a human or animal.
