anode means including a lithiummember within the casing. is thankful to RIKEN materials characterization team for their support on transmission electron microscopy operation.Thank you for visiting nature.com.
In particular, lid member 17 is provided with an aperture or opening of sufficient size so that lead 28 and the ferrule 40 around it can extend through and beyond lid 17 whereby an external electrical connection can be made to the anode of the cell. Cathode material or depolarizer 50 is prepared by heating the organic material, i.e., 2-vinyl pyridine, to a temperature greater than the crystallization temperature of iodine and then adding iodine to this heated material. Therefore, X-ray views can be made through these portions of bottom 11 and end walls 14, 15 thereby permitting relatively easy X-ray examination of the interior of a completed and sealed cell.The cell of the present invention further includes anode means comprising a pair of lithium members or plates 22, 24 having an anode current collector element 26 sandwiched or positioned therebetween. Al-The lithium-iodine cell according to the present invention operates in the following manner. Also, an Anode paste composed of Graphite is spread onto both sides of a sheet of copper foil. Seal 44 preferably meets or contacts seal 42. Cathode means 50 preferably comprises a charge transfer complex of an organic material and iodine. 2 is a sectional view taken about on line 22 in FIG. The Lithium Battery refines the kayak battery beyond the heavy and cumbersome marine batteries of the past. H01m 11/02 iodine-containing material in Contact with both the [58] Fi ld f S ar h 136/6 F, 6 L 6 LF, 6 A casing and the lithium member. A cell according to claim 3, wherein said firstnamed seal is molded in said ferrule.a. Therefore, lithium-iodine cells heretofore available have included insulation between the cathode material, i.e., the iodine-containing complex material, and the cell outer case or can.One area of use of the present invention is in providing electrical power safely to inaccessible devices in the human environment, for example to an implanted cardiac pacemaker, although the principles of the present invention can be variously applied. Unlike alkaline batteries, lithium batteries are reactive and contain hazardous materials. Pacemakers and other implantable medical devices use specially designed lithium-iodide batteries that can last 15 years or longer before replacement is necessary.
said sealing means shielding said conductor means from said iodine-containing material and electrically insulating said conductor means from said casing;12. A common case cathode is undesirable if it occurs randomly during cell operation. whereby an electrical potential difference exists between said conductor means and said casing during operation of said cell. When making Lithium Ion batteries, Manufactures, start by creating a Cathode paste composed of LiCoO2, which, is spread onto both sides of a sheet of aluminum foil. The anode conductor is positioned in a ferrule 5 References Ci which is sealed at the end adjacent the anode with ma- UNITED STATES PATENTS terial which is non-reactive with iodine and which is provided with an hermetic seal at the other end. In particular, any migration of the iodine-containing complex of material 50 directly to anode current collector 26 or directly to anode lead 28, instead of first reacting with a lithium member of the anode will result in the condition of electronic conduction thereby creating a short. In a lithium-iodine cell including a casing and.b.
