摘要： PROBLEM TO BE SOLVED: To make performance hard to degrade to vibration and a shock even at a high temperature by arranging a silicone elastic body in the whole or a part of a place where a battery and a battery case can contact with each other, and holding a shock absorbing function between the battery and the battery case. SOLUTION: Cylindrical lithium ion secondary batteries are used by eight pieces as batteries 2, and are arranged in two stages in a battery case 4 through a spacer 3. A material by working silicone rubber in an o ring shape is used on outer peripheral surfaces of the batteries 2 as a shock absorbing material 1 of a silicone elastic body, and is fitted in so as to be brought into close contact with the outer peripheral surfaces of the batteries 2. At this time, an O ring is arranged so as to exist between an inner wall projecting part of the battery case 4 and the outer peripheral surfaces of the batteries 2 and between an end part of the spacer 3, a bone part and the outer peripheral surfaces of the batteries 2. In the silicone elastic body such as silicone rubber, its maximum working temperature is about 280 deg.C, and a shock absorbing function is not lost even at a high temperature, and even if vibration and a shock are applied, the batteries 2 hardly degrade in performance.

摘要： PROBLEM TO BE SOLVED: To suppress upward elongation of electric collectors of respective electrode plates and prevent separation of active materials from the electric collectors and rupture of the electric collectors by installing an acid resistant frame, which applies pressure to respective electrode plates composing a unit of electrodes, in a space between the unit of electrodes and a battery jar lid. SOLUTION: In a sealed lead-acid battery, an acid resistant frame 3 to apply pressure to respective electrode plates constituting a unit 1 of electrode plates is installed in a space between the unit 1 of electrode plates and a battery jar lid 4. Consequently, the upper ends of respective plates are pushed by the acid resistant frame 3 and the upward elongation of electric collectors of respective electrode plates can be suppressed. As a result, separation of electrode active materials from the electric collectors due to the upward elongation of the electric collectors and rupture of the electric collectors can be prevented, so that taking out of energy of the battery can be carried out without a trouble. Moreover, since the electric collectors are not extended upward over a retainer, short circuit between electrodes with different polarity, which generally occurs above the retainer can be avoided and a risk of firing can be also avoided.

摘要： PURPOSE:To effectively utilize a positive electrode active material, improve the energy density of a battery, and provide a stable battery life by providing negative plates connected with a lead foil on both surfaces of a positive plate. CONSTITUTION:Two negative plates 1 having a thickness half as much as the thickness of a general negative plate are prepared, and the single negative plates are connected to each other by electric welding or soldering welding with a foil 2 mainly consisting of lead softer than a grating composition being disposed in the meddle or soldering to form one determined negative plate 11. The negative plate 11 is wound around a positive plate through an electrolyte holding body to form an electrode plate group, and this electrode plate group is lapped in a synthetic resin film. Thus, the weight energy density is improved, and the life is extended.

摘要： PURPOSE:To increase capacity by arranging a highly water-absorbing resin or a gelled electrolyte between positive and negative active materials and by forming an electrolyte retaining layer over the whole upper part of them. CONSTITUTION:A gelled electrolyte 9 is arranged between a positive electrode 1 and a negative electrode 2. A positive current collector 4 and a negative current collector 7 are arranged in the lower part of each of a positive active material 3 and a negative active material 6. A nonwoven fabric mainly comprising inorganic fibers or organic fibers is arranged as an electrolyte retaining layer 5 over the whole upper part of the active materials 3, 6 and the electrolyte 9, then the whole of them is sealed with an airtight resin film 8. When a battery is discharged, discharge reaction continues through the layer 5, and when the battery is charged, gas absorbing reaction proceeds through the electrolyte 9. The amount of electrolyte required for reaction between the electrodes 1 and 2 is always retained and capacity is increased.

摘要： PROBLEM TO BE SOLVED: To infiltrate electrolyte evenly into the middle section of each plate in a plate group within a short time and improve stable battery characteristics, by accommodating a plate group in a battery jar such that it is wrapped with a retainer which includes silica in the center of a plane facing the group, is bag-shaped, and has liquid retention lower than that of a retainer between plates in a pressurized state in the battery jar, and by injecting electrolyte for battery-jar formation. SOLUTION: A bag-shaped retainer 4 decreases liquid infiltration rate outside of a plate group, prevents an electrolyte from penetrating rapidly, and allows the electrolyte to move easily in the plates. Therefore, it is made of nonwoven glass fiber material which has liquid retention lower than that of a retainer 3 in the plate group. Furthermore, the bag-shaped retainer 4 has a structure where surfaces other than its top are continuous so as to produce adhesion to the plate group and supply the electrolyte evenly all around plates. Because a silica adding section 6 is placed in the center of a plane facing the surface of the plate group, the electrolyte can easily move to the center of the plate group during the electrolyte injection, and adhesion to the whole plate group becomes higher.

摘要： PROBLEM TO BE SOLVED: To provide a sealed lead-acid battery to restrain stratification of an electrolyte without greatly lowering diffusibility of the electrolyte and prolonging an injection time for the electrolyte. SOLUTION: Silica powder is not carried in a lower side region portion 13b3 of a retainer 13 located in a lower region of a pole plate group 14 to apply group pressurizing force to make stratification of an electrolyte difficult. Silica powder is carried in a band-like shape to a counter portion of a positive pole plate 11 in a boundary area between the lower region portion 13b3 and an upper region portion above the portion 13b3 (silica carrying band-like portion 13a in the lower side). The upper region portion is vertically partitioned into two non-silica carrying region portions 13b1, 13b2, and silica is carried in a band-like shape to a counter portion of the positive pole 11 in a boundary area between the the two region portions (silica carrying band-like portion 13a in the upper side). Length dimensions in the vertical directions of region portions 13b1-13b3 are made to be 10 cm or less respectively.

摘要： PURPOSE:To increase binding force with a casting surface remaining, except both pressed surfaces, improve a battery energy density, and keep a battery life characteristic, by pressing a grid body after casting to decrease the thickness thereof. CONSTITUTION:A grid body after casting is hydraulically pressed to obtain a grid body 1. A casting surface 1a remains except both pressed surfaces in the obtained grid body 1. When the grid body 1 is filled with paste to be formed into an electrode plate, the electrode plate thickness can be decreased while a boundary surface between the active substance and the grid body is keeping the same condition as the cast grid body. Consequently, bonding force is excellent, and an active substance utilization rate can be increased without the problem of corrosion.

摘要： PURPOSE:To stabilize the capacity and the life of a battery and prevent defects owing to pin holes by setting a synthetic resin frame in the outside of a film made of synthetic resin. CONSTITUTION:A group of electrode plates of formed caps containing a retainer composed of one cathode plate, one anode plate, and glass fiber and a safety valve part is wrapped with a film made of synthetic resin. Then, an electrolyte is poured to prepare an elemental battery. Five, for example, of the elemental batteries are stacked in series and pressed by a synthetic resin from to give a combined battery. With this structure, stacking is carried out easily and since the pressure is applied to the whole of the electrode plates, the capacity and the life of the battery are stabilized. Moreover, the defects owing to pin holes easily formed in the manufacturing process can be prevented.
