Problems solved by technology

[0002] The disadvantage of the traditional ordinary lead-acid battery tubular positive plate is that the lead bars of the positive plate grid are relatively thick, occupying a lot of space in the entire plate, so that the active material is relatively small, resulting in a relatively low battery capacity , resulting in shorter mileage for electric cars, sightseeing buses, etc. powered by the battery
Positive plate grid alloy has relatively low density, poor corrosion resistance, and short battery life

Abstract

The invention belongs to the field of batteries, and particularly relates to an optimized thin-type and an electrode-tube-type seal power lead-acid storage battery. The optimized thin-type and the electrode-tube-type seal power lead-acid storage battery comprises a positive electrode plate and a negative electrode plate, wherein the positive electrode plate is made of a rare earth alloy, the negative electrode plate is prepared from the following raw materials: lead powder, barium sulfate, humic acid, complex tannin extract, carbon black, ion exchange water and vitriol. The invention also provides a preparation method of the optimized thin-type and an electrode-tube-type seal power lead-acid storage battery. The preparation method comprises the following steps: melting the rare earth element into the lead so as to prepare a positive plate grid, enabling a sheath and a dacron calandria to sleeve the grid, then filling the powder, smashing an upper back cover, soaking, solidifying and drying, so as to prepare the positive electrode plate; and after preparing the positive electrode plate and the negative electrode plate, assembling and forming the positive electrode plate and the negative electrode plate into a finished battery. The rare earth alloy is adopted by the positive electrode plate, so that the mechanical strength of the grid and the corrosion resistance of the grid are improved, the service life of the battery is prolonged, the complex formula of the negative electrode plate is used for improving the battery active substance use ratio and the battery capacity, and the low-temperature discharge performance of the battery is enhanced.
