A cell according to claim 7, wherein said anode means further comprises a frame member continuously surrounding the peripheral edges of said lithium members in a manner sealing said edges, said electrical lead extending through said frame member. It is a more particular object of this invention to provide a lithium-iodine cell wherein the anode current collector is completely sealed or shielded from the iodine-containing cathode material, from the cathode current collector, and from the cell outer casing or can. i. 2 is a sectional view taken about on line 22 in FIG. A _____ion is a covalently bonded group of atoms that has a positive or negative charge. An electron donor is necessary to give the iodine sufficient conduc tivity for propoer cell operation. The anode assembly comprising lithium elements 22, 24 and current collector 26 is fitted within an anode holding means or frame 34 which embraces the anode assembly in a manner exposing at least one lithium surface. 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. In fact, research shows that the battery will be able to reach an 80 percent charge in only five minutes! Concerning output per weight, a battery reproduces only one percent of the energy by different fossil fuels. By having all parts of anode current collector 26 and conductor 28 shielded or sealed from cathode material 50 and from the metal casing, no insulation is needed between the cathode material 50 and the metal casing. 12. Frame 34 is of sufficient size and positioned within the casing so that one edge or surface thereof contacts the casing bottom 11, the frame 34 is spaced between the side walls 12, 13, and opposite edges of the frame contact or engage the inner surfaces of casing end walls 14, 15. ICD shocks require up to 830 V of stored charge per full output ICD shock and require large capacitors. All parts of anode current collector 26 and electrical lead or conductor 28 connected thereto are shielded from the cathode material, and from the cell casing. By eliminating the need for insulation between cathode material 50 and the metal casing, the cell of the present invention can be assembled relatively quickly and economically and requires fewer parts. It is also the standard electrolyte in artificial pacemakers due to the long cycle life it enables. said ferrule being sealed at one end to said anode means and extending along the portion of said conductor means within said casing; e. cathode means comprising iodine-containing material within said casing and in operative contact with said exposed surface portion of said lithium element and with a major portion of the surface of said casing in a manner such that said casing serves as a cathode current collector; and. Do You Restore Lithium Ion Battery in Freezer? 3. In particular, seal 44 can be provided by filling the inner volume of ferrule 40 with Teflon material which then is cured under suitable conditions of heat and pressure. Frame 34 is of Teflon or any similar material which is non-reactive with iodine. It can participate in various hydrates. The solid is used as a phosphor for neutron detection. The amount of iodine added, however, should not be so excessive as to interfere with surface contact between the lithium surface of the anode and the cathode material complex 50 by recrystallization. 4. When exposed to air, it becomes yellow in color, due to the oxidation of iodide to iodine. 11. The resulting assembly then can be fitted in frame 34. 8. 11. In the cells, the negative electrodes are made of graphite, which is a form of carbon, while the positive electrodes are made of metal oxides. 14. The cell of the present invention further comprises means for sealing the anode current collector lead or conductor from the cathode of the cell. 1, 1975 LITHIUM-IODINE BATTERY Primary Examiner-Anthony Skapars l W] l N.Y. [75] nventor lson Greatbatch, C arence Attorney g or Flrm chnstel & Bean [73] Assignee: Wilson Greatback Ltd., Clarence, [57] ABSTRACT 22 i1 Man 5, 1973 A lithium-iodine cell comprising a casing of electrically conducting material, an anode including a lith- [21] Appl' 338M ium element within the casing, an electrical conductor operatively connected to the lithium member and ex- [52] US. They also contain relatively high energy densities as well as specific energy and are made smaller and lighter for purposes of reducing the weight of the vehicle while increasing its performance. The anode can be formed by pressing the lithium members 22, 24 together against current collector 26 with a suitable force, for example about 3,000 pounds. Commonly, electric vehicles mostly make use of lithium-ion and lithium-ion polymer battery technologies. Another advantage of the'cell of the present invention is that by virtue of the foregoing arrangement, the metal casing becomes a very large cathode current collector thereby improving cell performance due to the relatively larger amount of cathode material in contact with the current collector. Which is better, ternary lithium ion batteries or lithium iron phosphate batteries? Battery Life. 10. A preferred organic material is 2-vinyl pyridine polymer. Generally, batteries used in electric vehicles are designed to offer a substantial lifespan of about 8 – 10 years of service with charge and discharge cycles included. causing the members 22, 24 to be bonded together in a manner sealing current collector 26 therebetween. For many decades now, the improvements and advances of lithium-ion batteries have solely been driven by high demands from many portable electronic devices.
