摘要： A positive current collector grid which has been coated with a grid coating of PbO2 particles in a polyacrylic acid solution. Solution may also contain isopropyl alcohol or other polymers such as polyvinylpyrrolidone, polyethylene oxide, and polystyrenesulfonic acid in place of or in addition to polyacrylic acid. PbO2 particles may be varied in size. Number of coatings may be varied. Coatings may be applied via a direct gravure method or sprayer method. Coated positive current collector grid may undergo drying process to remove some or all of the polyacrylic acid, other polymers and solvents, leaving a layer of close packed PbO2 particles adhered to the surface of grid.

摘要： A lead alloy for lead acid-battery grids which essentially consists of about 0.05-0.07 wt % calcium; about 0.09-1.3 wt % tin; about 0.006-0.010 % silver; about 0.0100-0.0170 wt % barium and about 0.015-0.025 wt % aluminum with the balance lead. This lead alloy allows the improvement of the age hardening step, by eliminating the high temperature treatment process required for silver alloys in the manufacturing of lead-acid batteries. By using this lead alloy, a longer service life of the lead-acid batteries are also obtained by increasing the corrosion resistance and the mechanical strength of battery grids manufactured by the book molding process. Additionally, the reduced silver level used dramatically mitigates the problem of silver elimination from the stream of recycled lead in the secondary production of this metal.
摘要翻译：用于铅酸电池网格的铅合金，其基本上由约0.05-0.07重量％的钙组成; 约0.09-1.3重量％的锡; 约0.006-0.010％银; 约0.0100-0.0170重量％的钡和约0.015-0.025重量％的铝，余量为铅。这种铅合金可以通过消除银合金制造铅酸电池所需的高温处理工艺来改善时效硬化步骤。通过使用该铅合金，通过提高通过书本成型工艺制造的电池网格的耐腐蚀性和机械强度，也可以获得铅酸电池的更长的使用寿命。此外，所用的还原银水平显着地减轻了在这种金属的二次生产中从再生铅的流中除银的问题。

摘要： A method of forming battery grids or plates that includes the step of applying a lead alloy coating to a continuous strip of interconnected battery grids formed from a lead alloy grid material is disclosed. The battery grids may be formed by a continuous battery grid making process such as strip expansion, strip punching, or continuous grid casting. In one version of the method, the grid wires of a continuous strip of battery grids produced by a punching process are immersed in a melt of the lead alloy coating. In another version of the method, the grid wires of a continuous strip of battery grids produced by a punching process are deformed such that the grid wires have a cross-section other than the rectangular cross-section produced by the punching process and the strip of interconnected grids is immersed in a melt of the lead alloy coating. The method increases the cycle life of a battery.

摘要： The present invention provides a current collector for a battery which comprises a lead or lead alloy substrate and a thin cladding of tin, batteries utilizing such a current collector and methods for manufacturing such batteries. Preferably the tin cladding is composed of substantially pure tin and the concentration of the tin cladding relative to the weight of the current collector (i.e., the combined weight of the substrate and cladding) is less than 4% by weight. The tin cladding forms a noncontinuous layer over the outer surface of the substrate such that there are interspersed regions of lead and tin at the current collector surface. Batteries utilizing such current collectors exhibit marked improvement in performance compared to similar cells composed of tin alloys. In particular, batteries using current collectors of the present design offer superior cycle life and shelf life performance.

摘要： A precursor chemical compound is applied to a surface sought to be coated, and subjected to a rapid thermally activated chemical reaction process (RTACRP) in which the temperature is quickly raised and lowered. The desired coating is formed from the precursor chemical compound by a chemical reaction at the elevated temperature. The structural/chemical integrity of the surface is preserved due to the use of RTACRP. The approach may be used to manufacture a high-energy density lead-acid battery.
