摘要： PURPOSE:To increase the cell capacity by providing positive and negative electrodes,one of which being made of conductive polymer, and an electrolytic solution made from cold fused-salt. CONSTITUTION:Polyacetylene is used for both positive and negative electrodes and cold fused-salt is used as the electrolytic solution. Typical cold fused-salts are mixture of n-butyl-pyridiniumchloride and aluminum chloride, mixture of n-ethyl-pyridiniumchloride and aluminum chloride, and mixture of 1-methyl-3 ethylimidazoliumchloride and aluminum chloride. Use of cold fused-salt as the electrolytic solution greatly reduces the volume of the electrolytic solution and thereby enables the cell capacity to be increased in a given constant volume.

摘要： PURPOSE:To increase cycle performance of using a clad plate of a metal plate which is alloyed with lithium and a metal plate for negative case as a negative can, and locating the metal plate which is alloyed with lithium inside the case. CONSTITUTION:A positive electrode 2 is pressed against the inner bottom of a positive case 1 made of a 0.33mm thick stainless steel plate through a positive current collector 3. A negative can also serving as a negative electrode is made of a clad plate of a 0.1mm thick aluminum plate 5 acting as negative electrode and a 0.2mm thick stainless steel plate 6 serving as negative can, and the aluminum plate 5 locates inside the can. By using the negative can combined with the negative electrode, its thickness is increased to 0.3mm and mechanical strength in sealing part is increased. Thereby, the effective volume within a battery is increased and the volume of electrolyte is also increased and the cycle performance is improved.

摘要： PURPOSE:To obtain a non aqueous electrolyte secondary cell having an excellent cycle characteristic by composing a negative electrode with a lithium alloy and a polyolefin system binding agent. CONSTITUTION:A negative electrode is composed of a lithium alloy and a polyolefin system resin binding agent. Polyolefin system resin includes polyethylene. Lithium-aluminum alloy is preferable as the lithium alloy. Since the negative electrode is composed not only of a lithium alloy but also contains a binding agent, the mechanical strength is improved to suppress falling of the negative electrode thus improving the cycle characteristic. Since the binding agent is composed of a polyolefin system resin which will never react with lithium, missing of the binding effect due to reaction of lithium with fluororesin which is conventionally employed as a binding agent will never occur.
摘要翻译：目的：通过组成负极与锂合金和聚烯烃系粘合剂，获得具有优异的循环特性的非水电解质二次电池。构成：负极由锂合金和聚烯烃系树脂粘合剂构成。聚烯烃体系树脂包括聚乙烯。优选锂 - 铝合金作为锂合金。由于负极不仅由锂合金构成，而且还含有粘合剂，所以提高了机械强度，抑制了负极的下降，从而提高了循环特性。由于粘合剂由不会与锂反应的聚烯烃系树脂构成，所以不会发生由于锂与氟树脂与常规用作粘合剂的反应引起的结合效果的缺失。

摘要： PURPOSE:To obtain an excellent charge/discharge cycle property without reducing the cell voltage and the energy density, by furnishing a fluorine resin body between the positive and negative electrodes. CONSTITUTION:The cell has a positive electrode made of a rechargeable active substance and a negative electrode of lithium as the active substance, and between the positive and the negative electrodes is furnished a fluorine resin body. When the electrically separated lithium, grown up in a branch form, contacts the fluorine resin body, they make a chemical reaction as the following reaction formula and the lithium is consumed away and prevented from reaching the positive electrode: nLi+(CF)n nLi-nC In this case, the fluorine resin body is preferable to be separated from both electrodes, but there is no problem even through it contacts either side. In such a reason, the inner short circuit is restricted and the charge/discharge cycle property is improved.

摘要： PURPOSE:To suppress the dendritic growth of lithium and reduce the fall in the voltage of a secondary cell, by providing a lithium alloy or a lithium- alloying metal in the peripheral portion of a negative electrode for which lithium is used as active material. CONSTITUTION:A positive electrode 7 made of a rechargeable active material such as molybdenum trioxide and vanadium pentoxide is provided in a positive electrode can 1. A separator 9 is interposed between the positive electrode 7 and a negative electrode for which lithium is used as active material. A secondary cell is thus built. The negative electrode is composed of a central portion 4 made of a lithium-metal plate, and a peripheral portion 5 made of a lithium- aluminum alloy or the like. Since dendritic growth is suppressed in the peripheral portion 5 in which the dendritic growth would be likely to take place, an internal short circuit is effectively prevented. Since not all of the negative electrode is made of the lithium alloy, the fall in the voltage of the cell is eliminated to improve the charge/discharge cycle property thereof.

摘要： PROBLEM TO BE SOLVED: To improve a charge-and-discharge cycle characteristic by providing a negative electrode containing an active material consisting of lithium or a lithium alloy and a positive electrode having an active material consisting of a manganese oxide having an intermediate crystal structure between spinel type LiMn2 O4 and λ-type manganese dioxide obtained by partially removing lithium contained in spinel type LiMn2 O4 by thermal treatment. SOLUTION: Spinel type manganese dioxide (LiMn2 O4 ) is obtained by mixing Mn2 O3 or optional manganese dioxide to lithium carbonate in a mole ratio of Mn: Li=2:1 followed by heating at 800-900 deg.C. This spinel type manganese dioxide is dipped in sulfuric acid to prepare manganese oxide having an intermediate crystal structure between spinel type LiMn2 O4 and λ-type manganese dioxide. By this acid treatment, l/2 of the lithium contained in the spinel type LiMn2 O4 is removed. Prescribed quantities of a conductive agent and a binder are mixed to this manganese oxide to form a positive electrode mix.

摘要： PROBLEM TO BE SOLVED: To restrain the formation of a lithium dendrite, improve a cycle characteristic, increase the total discharging capacity, and improve its shelf life in a high temperature condition by controlling discharging capacity in a charging discharging cycle below a specific rate in battery capacity. SOLUTION: Discharging capacity of a nonaqueous electrolyte secondary battery is controlled below 30% of the battery capacity, and even if a charging- discharging cycle is repeated, a lithium dendrite generated in a negative electrode is restrained. It is desirable that a γ-β phase and β phase manganese oxide is used as a positive electrode active material in a positive electrode. It is desirable that lithium-aluminum alloy is used as a negative electrode active material in a negative electrode. The content of aluminum in the lithium- aluminum alloy is desirably 0.1 to 10.0wt.%. The ratio of (the negative electrode active material/the positive electrode active material) is preferably 1.5 or less. Therefore, since there is no need to pack excess lithium in a battery, battery capacity can be improved by that extent.
