Abstract

The invention discloses a positive lead paste for lead-acid storage batteries, which contains the following substances in mass percentage: 71%-79% of lead powder, 8%-12% of a sulfuric acid solution, 10%-12% of deionized water, 2%-5% of red lead, 0.1%-0.3% of sodium perborate, 0.06%-0.18% of antimony oxide, 0.15%-0.2% of graphite powder and 0.07%-0.08% of fibers. According to the positive lead paste for lead-acid storage batteries, red lead is added on the basis of introducing boron and antimony elements, and the amount of antimony oxide is controlled, thereby reducing the amount of antimony while ensuring the excellent corrosion resistance of the lead paste, enhancing the electric conductivity of the batteries and preventing significant voltage drop, improving the high temperature resistance of startup lead-acid storage batteries, and thus achieving the purpose of simultaneously improving he corrosion resistance and service life of the startup lead-acid storage batteries.

Description

technical field [0001] The invention relates to the technical field of storage battery preparation, and more specifically, relates to a lead-acid storage battery cathode lead paste and a preparation method and application thereof. Background technique [0002] At present, most manufacturers of grid alloys for start-up maintenance-free batteries on the market use Pb-Ca-Sn-AL alloys, and their grid forming processes mainly include gravity casting, stretching, punching, continuous casting and rolling. There are several types, among which the grid of start-up lead-acid batteries is basically formed by gravity casting. During the storage process of start-up lead-acid batteries, it is found that many brands have not been used in batches, and the storage time is 3 to 12 months or one year. For more than one year, the voltage drops significantly, and the vehicle cannot be started. Later, through the analysis of this type of battery, the failure of the battery was due to the active ...
