    摘要： Battery-powered implantable medical devices require a suitable method for indicating end-of-service of the power source so that there is ample time for elective replacement of the device and/or power source. The present invention utilizes mixed cathode materials preferably comprising a major portion of a fluorinated carbon and a minor portion of a metal-containing material. This mixed cathode formulation is characterized by two, discretely different operating voltages, the second of which may be used as an end-of-life indicator.

    摘要： A fabric separator woven from synthetic halogenated polymeric fibers for use in an electrochemical cell comprising a Group IA, IIA and IIIB metal anode and a depolarizer/catholyte or a solid cathode/electrolyte system, is described. The separator is resistant to the highly oxidizing components present in the cell, is tear resistant and has a reduced thickness to minimize the diminishing effect of the separator on the volumetric amount of active components in the cell. The separator can be used by itself or as a laminate with a microporous film, preferably made of a fluoropolymeric fiber.

    摘要： A cell construction that makes use of unbalanced electrode components or portions comprising one of the electrodes of an electrochemical cell to provide an end-of-life indication, is described. The unbalanced electrode components can have dissimilar physical dimensions or dissimilar percent loading of electrode active material. This renders the one dissimilar electrode component having the lesser physical dimension, i.e., lesser surface area or thickness, or lesser quantity of electrode active material electrochemically unreactive prior to the other electrode component during the course of cell discharge. Upon the early exhaustion or unreactiveness of the one dissimilar electrode component, the total cell interelectrode working capacity is reduced by a predetermined factor. The remaining functional electrode component provides the cell with sufficient capacity for electrical discharge at a predetermined lower energy level.
