摘要： A method of manufacturing a battery containing a non-circular spiral electrode unit forms a true circular or elliptical cylindrical electrode unit by winding positive and negative electrode plates with a micro-porous polymer film separator disposed between the two electrode plates. The cylindrical electrode unit is pressed from both sides into a non-circular spiral electrode unit and inserted into an external case to form a battery. When the cylindrical electrode unit is pressed into a non-circular spiral electrode unit, the separator gurley value of the pressed non-circular spiral electrode unit is arranged to be in the range from 110% to 150%, where the separator gurley value of the cylindrical electrode unit is 100%.

摘要： A battery is provided which includes: an electrode roll having a positive-electrode plate, a negative-electrode plate and a separator interposed therebetween; a battery casing accommodating the electrode roll; and a sealing plate laser-welded to an open end of the battery casing. On the outermost periphery of the electrode roll is located an electrode-base-exposed portion of either one of the positive-electrode plate and the negative-electrode plate. The sealing plate is laser-welded to the battery casing in a state that a collector tab formed by incising the electrode-base-exposed portion and folding the incised portion is held between the periphery of the open end of the battery casing and the sealing plate. With this construction, the electrical connection between the collector tab and the battery casing is assuredly achieved simultaneously with the sealing of the battery to suppress a reduction in the closed-circuit voltage and an increase in the internal resistance. In addition, the battery of this construction can be fabricated by a simplified battery fabrication process.

摘要： Novel lead location and winding configuration allow more efficient spiral electrode fabrication for a battery that is less susceptible to internal short circuits. The battery has separator material sandwiched between positive and negative electrode strips, which are rolled into a spiral electrode unit. The electrodes have active material that covers a core except in regions where leads are attached. One lead is positioned at the outermost winding, and both sides of each lead face either separator material only or the same polarity electrode via separator material. A special lead taping processing step is eliminated.

摘要： The outside edges of a sealing plate are weld attached to close off an opening in a metal case of a prismatic battery of this invention. The sealing plate has an electrode rivet which passes through an electrode hole and sandwiches an insulating gasket to attach in an electrically insulating fashion. The battery case houses an electrode group with either its positive or negative electrode plate connected to the electrode rivet. The sealing plate has a periphery region or reinforcement rib which is formed thicker than the rivet region where the electrode rivet attaches, and the outside edges of this reinforcement rib are weld attached to the case.

摘要： In a lithium battery having a negative electrode formed with lithium as active material and the positive electrode formed with manganese dioxide, carbon fluoride or the like as the active material, the discharge capacity of the negative electrode is made smaller than the discharge capacity of the positive electrode, whereby a drop in the battery voltage during the final discharge stage is steepened, and prevents a device using such a lithium battery as a power supply from operating in an unstable manner, thereby improving the reliability of such device.

摘要： The present invention discloses a battery in which a plurality of positive and negative electrodes are alternately superposed, with each of separator layers therebetween, in the form of flat package. Through-bores are centrally defined in the electrode having one polarity interposed between a pair of electrodes having the other polarity, and both separator layers sandwiching said electrode having said one polarity. Passed through these central bores is an electrical contact member, of which at least the portion in contact with said electrode having said one polarity, is coated with insulating material. Said pair of electrodes having said other polarity are therefore electrically connected to each other by said electrical contact member. Thus, electric contact between the electrodes having a same polarity may simply be provided, internal short-circuit in the battery may be prevented and the assembling of the battery may be facilitated.
