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.

Abstract: The present invention related to an electrochemical cell comprising an anode of a Group IA metal and a cathode of a composite material prepared from an aqueous mixture of iron sulfate, cobalt sulfate and sulfur. The cathode material of the present invention provides an increased rate pulse performance compared to iron disulfide cathode material. This makes the cathode material of the present invention particularly useful for implantable medical applications.

Abstract: In various examples, a feedthrough seal apparatus is configured to seal an opening in a device. The device includes a case surrounding an interior space, the case including the opening therein to allow access to the interior space from an exterior of the case. The feedthrough seal apparatus includes a plug disposed within the opening of the case. The plug is formed from at least one of a polymeric material and an adhesive material. The lead wire extends through the plug, such that a first end of the lead wire is disposed within the interior space of the case and a second end extends from the plug to the exterior of the case. The plug is configured to electrically insulate the lead wire from the case. Some examples include a method of making the feedthrough seal apparatus.

Abstract: The present invention relates to an electrochemical cell comprising an anode of a Group IA metal and a cathode of a composite material prepared from an aqueous mixture of iron sulfate, nickel sulfate, and sulfur. The cathode material of the present invention provides for a lithium electrochemical cell having an increased operating voltage and power performance with high discharge capacity as compared to a lithium cell comprising nickel disulfide cathode material. In addition, the cathode material of the present invention exhibits a smaller initial irreversible voltage loss as compared to iron disulfide. This makes the cathode material of the present invention particularly useful for implantable medical applications.

Abstract: The application of a titanium hydride coating on a ceramic, preferably an alumina ceramic, as a facile and inexpensive approach to bond gold to the ceramic during brazing is described. During the brazing process, the deposited titanium hydride is first partially decomposed to form pure titanium intermixed with titanium hydride. The combination of pure titanium and titanium hydride contributes to improved adhesion of gold with the alumina ceramic without any detrimental reaction between pure titanium and gold. The titanium hydride coating can be applied by dip/spray/paint coating.
