摘要： PURPOSE:To obtain a nonaqueous solvent battery with large battery capacity and preferable charging/discharging cycle by melting vanadium pentoxide as positive electrode active material, at a specified temperature and employing the compound obtained by cooling the melted vanadium pentoxide. CONSTITUTION:A group of electrodes 3 are enclosed in a stainless case 1 through an insulator 2. The group of electrodes 3 has the structure that a strip member in which positive electrodes 4, separators 5 and negative electrodes 6 are sequentially laminated is wound in spiral with a negative electrode being provided outermost. As for the active material of the positive electrode 4, powders of V2O5 and P2O5 are mixed with each other, melted at 800 deg.C to 1200 deg.C and cooled down rapidly to obtain pelletized material. This material is ground into powder of noncrystal V2O5 compound. The powder is mixed with powder of acetylene black and polytetrafluoroethylene to be a sheet which is pressed and fixed on an expander metal current collector to be a strip. Therefore, a nonaqueous solvent battery with large battery capacity and preferable charging/discharging cycle is obtained.

摘要： PURPOSE:To prolong the charge-discharge cycle life, increase the discharge capacity, and reduce the self-discharge in a nonaqueous solvent battery by drying its positive electrode at a specified temperature in case of manufacturing said battery. CONSTITUTION:In case of manufacturing a nonaqueous solvent battery, its positive electrode is dried at temperature range of 80-200 deg.C. The following types of material are used for the positive electrode: molding type, sheet type, film type or other types of material made from, for instance, amorphous vanadium pentoxide powder as main positive electrode active material, conductive material and binder. Furthermore, the drying of the positive electrode may be done in the air, but it is better to do in dried inert gas flow or under vacuum suction from a viewpoint of enhancing drying effect.

摘要： PURPOSE:To prevent the generation of short circuit during the charge and the discharge and to maintain the discharge capacity by making the area of a negative electrode larger than that of a positive electrode, and arranging a part of the periphery of the negative electrode not to oppose to the positive electrode. CONSTITUTION:A negative electrode 4 which consists of lithium or a lithium alloy is made 39mm in width and 130mm in length, while a positive electrode 6 is made 33mm in width and 120mm in length, for example, and they are wound in a spiral form placing a separator 5 between them. The area of the negative electrode 4 is made larger than that of the positive electrode 6 and the negative electrode 4 is superposed on the positive electrode 6 projecting 1mm from both ends along the longitudinal direction of the positive electrode 6. As a result, the tranfer probability of lithium ions taken in to the positive electrode 6 in the discharge to the negative electrode 4 is increased, and the lithium is not deposited easily on the inner wall of the metal container 1. Consequently, a short circuit between the deposited lithium and the positive electrode 6 is prevented, the deterioration of capacity is suppressed, and the charge and discharge performance is improved.
