Abstract

The invention provides a preparation method of a lead-acid colloid storage battery. According to the invention, the partition plate main body is glass fiber, and by adding a hydrophilic material coated hydrophobic fiber, the problem of non-uniform mixing of glass fiber and hydrophobic fiber during slurrying can be solved. In addition, in a drying process, the hydrophilic material decomposes naturally, so that a certain amount of oxygen channels exist in the partition plate. Pole plates adopt tight assembling design, and part of nanoscale gas phase SiO2 can penetrate the partition plate. The electrolyte solution contains gas phase SiO2, and guarantees that the partition plate is in a liquid-rich state during use, and stratification does not occur to the electrolyte solution. At the same time, the partition plate also contains a certain amount of oxygen channels, thus being able to the long-life, high temperature environment and other special use demands of the storage battery.
