摘要： PROBLEM TO BE SOLVED: To provide a lead-acid storage battery in which corrosion resistance of an electrode is improved. SOLUTION: At least either a carbon compound 5 and an oxide 7 is contained in a state of dispersion in a current collector 3 forming a positive electrode, a negative electrode, and an electrolytic solution. With this arrangement, the crystal particle diameter of the electrode 1, especially of the current collector 3 forming the positive electrode which is apt to generate corrosion of the battery, can be made smaller than that of a current collector of an electrode in a conventional lead-acid battery. Then, by making the crystal particle size small, the corrosion resistance of the electrode of the lead-acid battery can be improved since the total extended length of a crystal particle boundary 15 per unit weight and per unit area of the current collector 3 becomes longer and the margin for corrosion becomes longer.

摘要： PROBLEM TO BE SOLVED: To enhance the engine startability by setting the weight of a positive electrode grid body with lead as a main component to a specific range wt.% of a positive electrode active material quantity. SOLUTION: As results of CCA(Cold Cranking Ampere) test of batteries using 22.0 g (65 wt.% relative to a positive electrode active material quantity) of a positive electrode cast grid body, 23.7 g (70 wt.% relative to the positive electrode active material quantity) of a positive cast grid body, and 25.1 g (75 wt.% relative to the positive electrode active material quantity) of a positive cast grid body, respectively, all the batteries show 130 (A) or more. Where the occupancy rate of the positive electrode cast grid body is low, the conductivity is lowered and where the occupancy rate of the positive electrode cast grid body is too high, the positive electrode active material quantity is reduced to reduce the capacity so that the CCA value is lowered. The batteries thus can discharge large current, have high engine startability, and be adaptable as a vehicle-borne lead-acid battery.

摘要： PROBLEM TO BE SOLVED: To reduce the quantity of sodium lignosulfate in a negative electrode active material so as to lower unsatisfactory filling to improve the charging acceptability, and to reduce the calorific power to prevent the lowering of low-temperature high efficiency discharge capacity by adding sodium lignosulfate to a negative electrode plate for lead-acid battery restraining the flocculation of lead during the charging to refine lead particles, and adding a specified quantity of phosphoric acid or boric acid thereto. SOLUTION: A negative electrode active material paste formed by adding an addition agent such as sodium lignosulfonate and sulfuric acid to lead powder composed mainly of lead oxide, is filled in a collector, and aged, dried, and formed to obtain a negative electrode plate for lead-acid battery. At this stage, phosphoric acid or boric acid at 0.01-0.1wt.% (vs. lead powder) is added to the negative electrode active material. With this composition, the quantity of sodium lignosulfonate as a surfactant is reduced, and the paste is hardened to lower the imperfect filling and to improve the conductivity of an electrode plate and the charge acceptability is thereby improved.

摘要： PROBLEM TO BE SOLVED: To hold an active material use rate high and elongate the life of a storage battery by fixing tin dioxide powder in a paste active material layer, whose major material is lead powder, in such a state as biting therein and tightly bonding the most of the tin dioxide to the lead powder. SOLUTION: An active material paste is formed with active material power which is so obtained that tin dioxide collided with lead powder composed of lead compound of lead, lead monoxide, etc., at high speed by a high-speed flow impact method is made to bite in the surface part of the lead powder. Tin powder or tin compound powder, which are oxidated to become tin dioxide, can be used as substitute for the tin dioxide powder. The both of them are thus closely bonded together to enlarge their contact area so that the conductivity inside the positive active material layer is enhanced, while pulverization of β-type lead dioxide is effectively suppressed. Preferably, the tin in the tin dioxide powder is set to 0.01-5.0mol% in relation to the lead contained in the paste active material layer. It is preferable that the particle diameter of the lead powder.

摘要： PURPOSE: To provide a positive electrode plate for lead-acid battery capable of holding a high active material utilizing ratio over the life period and excellent in life performance, and also provide a lead-acid battery in which the hydrogen overvoltage of a negative electrode is never reduced. CONSTITUTION: A tin dioxide hydrate or tin dioxide hydrate doped with trivalent or penta-valent metal ion is present in a positive electrode active material. For example, sodium stannate trihydrate is dissolved in an aqueous solution of antimony trioxide, and diluted sulfuric acid is gradually added thereto with stirring to generate a gelled suspension of tin dioxide hydrate doped with trivalent antimony. Lead powder is kneaded while dropping the gelled suspension thereto, and the kneading is further continued while adding diluted sulfuric acid to prepare a paste positive electrode active material. A lead-acid battery is assembled by use of a positive electrode plate obtained by applying this paste positive electrode active material to a grid body.

摘要： PURPOSE:To improve the intensity of active material and non-active material, and to utilize red lead effectively by adding dilute sulfuric acid to red lead dispersed in the water, and after finishing the reaction, adding it to lead oxide, which is mainly composed of lead monoxide, and kneading it. CONSTITUTION:After distributing red lead in the water, dilute sulfuric acid is added thereto to make the red lead and the sulfuric acid react with each other. Lead sulfate generated by the reaction is kneaded with the lead powder, which is mainly composed of lead monoxide, to react and generate tribasic acid lead sulfate. Lead dioxide generated by the reaction of red lead and sulfuric acid is kneaded with lead powder, and distributed in the paste evenly. Generation of a large quantity of lead sulfate due to the reaction of red lead and sulfuric acid is eliminated when the electrolyte is filled at the time of formation, and the bonding force between active material grains can be maintained.

摘要： PURPOSE:To enhance forming efficiency and to prevent paste filling performance from being lowered by adding organic high polymer fibers coated with carbon and carbon black. CONSTITUTION:When organic high polymer fibers coated with carbon are added in active material, the skeleton of electron conductive net works is formed in green forming active material. The addition of particulate carbon black causes electron conductivity among the aforesaid fibers to be produced so as to allow the net works to be completed. In addition, the amount of carbon black to be added can be lessened less than a half of the former one, and the active material is prevented from dropping out due to a reduction in binding strength among active material particles, and concurrently the forming efficiency of active material not yet chemically treated can be enhanced. The amount of carbon black to be added is desirably in the range of 0.2 to 0.4wt.%.

摘要： PURPOSE:To improve chemical conversion efficiency and to prevent a plate from decreasing its life. CONSTITUTION:Lead dioxide and lead sulfate are left as produced by previously kneading minium with dilute sulfuric acid to manufacture active material use paste by kneading these leads with lead monoxide, dilute sulfuric acid and water. This active material use paste is applied to a collector to prepare a non-chemical conversion plate, and this plate is chemical conversion-treated to manufacture a positive plate for use of a lead-acid battery. Lead sulfate produced from the minium is changed into tribasic lead sulfate in the case of kneading with lead monoxide, and this tribasic lead sulfate becomes lead dioxide by chemical conversion treatment.
