摘要:
A cardiac pacer having an alkali metal-halogen cell comprising an alkali metal anode, preferably lithium, a solid alkali metal-halogen electrolyte and a cathode comprising a mixture of two halogens, for example iodine and bromine, the two halogens providing discharge of the cell at two different levels of cell output voltage. The two halogens are in different proportions by weight of the mixture thereby providing a two step output voltage-time characteristic. The second step or plateau in the output voltage characteristic provides an early warning of pacer battery exhaustion.
摘要:
A lithium-iodine cell comprising a casing of electrically conducting material, an anode including a lithium element within the casing, an electrical conductor operatively connected to the lithium element and extending out from the casing, and a cathode comprising iodine-containing material in operative contact with both the casing and the lithium element. The anode electrical conductor is completely sealed from the rest of the cell, and the casing serves as the cathode current collector. The anode operative surface is provided with a coating of an organic electron donor material. The anode is enclosed within an insulator element within the casing and a ferrule having one end within the insulator and the other end extending from the casing.
摘要:
A lithium-iodine cell comprising a cathode including a charge transfer complex of an organic donor component and iodine, an anode including a lithium element having a surface operatively contacting the charge transfer complex material, and a coating on the lithium surface of an organic electron donor material, preferably but not necessarily the organic donor component of the charge transfer complex. The organic electron donor material preferably comprises polyvinyl pyridine polymer and in particular two-vinyl pyridine polymer. A solution of two-vinyl pyridine polymer in benzene is brushed onto the anode lithium surface and then exposed to a desiccant. A number of coatings preferably are applied successively to provide a resulting or finished coating of increased thickness.

摘要:
A lithium-iodine cell comprising a casing of electrically conducting material, an anode including a lithium element within the casing, an electrical conductor operatively connected to the lithium member and extending out from the casing, and a cathode comprising iodine-containing material in contact with both the casing and the lithium member. The anode electrical conductor is completely sealed from the rest of the cell, and the casing serves as the cathode current collector. The anode conductor is positioned in a ferrule which is sealed at the end adjacent the anode with material which is non-reactive with iodine and which is provided with an hermetic seal at the other end.
摘要:
A solid state battery construction is disclosed wherein the anode structure can be formed from one of the compounds selected from the group consisting of lithium, lithium and magnesium, lithium and calcium, or lithium, magnesium and calcium. The cathode is formed of conductive metal such as stainless steel and nickel engaging an ionic conductive layer formed of one or more of the compounds selected from the group consisting of rubidium iodide, cesium iodide, tetramethyl ammonium iodide and mixtures of iodine and non-ionic organic compounds such as pyrene or polyvinylpyrene or ion exchange resins such as polyvinylpyridine. The battery structure utilizes two layers of lithium or lithium compounds which sandwich a screen member of nickel to form the conductive contact with the anode.
摘要:
An aqueous process for the preparation of a solid ionically conductive composition of matter having the formula MAg4I5 in which M is Rb, K, NH4, Cs, or a combination of these, Cs being present only as a minor constituent of M, comprising preparing a substantially saturated solution of MI in water, intimately admixing four molar equivalents of AgI with the MI solution to effect reaction between the MI and AgI, and removing the water to recover MAg4I5 as the synthesized ionically conductive composition.
