Abstract: An electrical energy power source comprises a casing made by micro-bonding an upper ceramic wafer and a lower ceramic wafer to the opposed surfaces of a ceramic ring. The upper and lower ceramic wafers have respective first and second conductive pathways extends therethrough. A first current collector supporting a first active material layer contacts the upper ceramic wafer and the first conductive pathway, and a second current collector supporting a second, opposite polarity active material layer contacts the lower ceramic wafer and the second conductive pathway. A separator resides between the first and second active materials, and an electrolyte filled into the casing through a fill port activates the active materials. The first and second conductive pathways serve as opposite polarity terminals for the power source.

Abstract: An lithium-iodine electrochemical cell and method of making is described. The cell comprises a lithium anode and a cathode of a charge transfer complex which includes iodine and preferably polyvinylpyridine. The iodine-containing cathode is in operative contact with both the anode the cell casing serving as the cathode current collector. Preferably the casing is composed of stainless steel that has been thermally annealed at temperatures of 1,800° F. or less. The annealed stainless steel has a grain size of about ASTM 7 or finer. When the iodine-containing cathode material in liquid form is filled into the casing, it contacts the inner casing surface. The passivation layer that subsequently forms at the contact interface affects cell impedance during discharge. It is desirable to maintain the internal impedance as low as possible.
