摘要： PROBLEM TO BE SOLVED: To accomplish improvement and stabilization of a life property of a battery by using Pb-Ca group alloy for a positive electrode grid, adding a specific quantity of Sb to a positive active material, and specifying density of the positive electrode active material to a specific value or more in a post- formation condition. SOLUTION: Into a positive electrode active material, Sb is added so that it exists in a ratio of 0.005-1.0% by weight to the active material weight and density of the positive electrode active material becomes 3.75g/cc or more in post-formation condition. In this process, As is added with Sb so as to exists in a ratio of 0.005-0.1%. Addition is carried out by using lead powder formed of alloy containing a predetermined quantity of Sb and As. For dispersing Sb in the active material uniformly, antimony sulfate and the like, which is previously finely pulverized by application of ultrasonic waves of 1-100 kHz so as to be dispersed in dilute sulfuric acid or water, may be added into a positive electrode paste during kneading the paste. In production, the time from liquid injection to the start of battery jar formation is 2 hours or less.

摘要： PROBLEM TO BE SOLVED: To improve the cycle life by using Pb-Sb based alloy containing a specific rate of Sb for a positive electrode and including lignin in a separator between a positive and a negative electrode plates. SOLUTION: Pb-Sb based alloy used for a positive electrode grid contains Sb more than 0.5% and less than 1.7%. This constitution can prevent early capacity reduction in the positive electrode plate, fall of the active material, and the extended grid. Addition of lignin to a separator layer captures Sb in the separator layer so as to suppress increase in water decomposition. The separator is set to a multi-layered structure of two or more layers and if the lignin content in the separator layer being in contact with the positive electrode plate is reduced lower than that in the other separator layers, an inferior effect caused by resolution of the lignin in the positive electrode plate in charging can be suppressed. If the lignin content in the separator abutting to the negative electrode plate is set lower than that in the other separators, inferior effects such as reduction in receipt of the charging of the negative electrode plate caused by excess of the lignin quantity around the negative electrode is suppressed.

摘要： PURPOSE:To improve charging/discharging cycle life of a sealed lead-acid battery for absorbing oxygen gas formed during charging into a negative electrode, by using a positive electrode lattice consisting of a lead-antimony alloy, and by providing an organic high polymer having an ion exchanging functional group between a positive electrode plate and a negative electrode plate. CONSTITUTION:The diameter of the primary particle of silica very fine powder used for an electrolyte holder is 10-40nm, and the surface area is 20m /g. A powder-form cation exchange resin of 200-400 mesh is used as an ion exchange resin, and the capacity of the exchange group of the resin is no less than 4.4meg/g-R. The lifetime is thus extended while the current decreasing is reduced. Since a lead-antimony alloy is used for a positive electrode lattice, degradation of positive electrode active material and the extension of the lattice are expected to be reduced. The movement of antimony from a positive electrode to a negative electrode is considered to be inhibited by the ion exchange resin. In the diagram indicating the result, the curves 1-3, of the curves indicating transition of discharging capacity and transition of the amount of reduced liquid, indicate the characteristic of the battery used.

摘要： PROBLEM TO BE SOLVED: To exhaust the generated heat outside so as to improve the lifetime characteristic and so prevent the runaway of heat by forming a wall of a battery jar out of a metal part at a specified ratio or more of volume, and using the material, which is obtained by coating this metal part with a resin. SOLUTION: A metal part such as iron or aluminum or the alloy, which is coated with a resin, is used for an outer wall part of the battery jar or a wall of a battery jar between the outer wall part and a cell. Desirably, as the metal part to be coated, a fin-shaped part or a heat pipe, or both of them are used. In the case where heat radiation of a battery is improved, use of a metal part over the whole surface of the battery jar is unnecessary. Metal part is used for the wall of the battery jar at 10% or more of volume. Efficient discharging performance during the lifetime is thereby remarkably improved by restricting the deviation of a negative electrode due to high temperature.
