Abstract

The invention belongs to the technical field of lead-acid batteries, in particular to a method for preparing colloidal electrolytes for lead-acid batteries, which solves the problems of serious hydration and stratification of colloidal electrolytes, high resistance and short service life in the prior art. The method comprises the following steps: mixing nano silicon dioxide and distilled water and dispersing, then adding methyltrimethoxysilane to raise the temperature and reacting to obtain mixed liquid A; mixing sulfate, nano boron oxide, 1-allyl-3-form Stir imidazolium chloride salt, fatty alcohol polyoxyethylene ether sodium sulfate and remaining distilled water to obtain mixed solution B; add dimethyl polysiloxane, lubricating grease and sulfuric acid into mixed solution B, and mix to obtain mixed solution C; Mix liquid A and liquid C, add stabilizer, and mix well. The preparation method of the present invention is simple, the preparation condition is mild, the cost is low, the obtained colloidal electrolyte has good thixotropy, small internal resistance, no acid leakage, no smoke, slow water loss speed and long service life, and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a method for preparing colloidal electrolyte of lead-acid batteries. Background technique [0002] In storage batteries, lead-acid batteries have the advantages of mature technology, cheap price, good charging and discharging performance, and safe use. As the most important stable power supply and DC power supply, they are widely used in aviation, railways, automobiles, ships, communications, and finance In various industries such as military and national defense, it has become an indispensable energy product in social production and human life. Lead-acid battery refers to a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. In the discharge state of the lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the chargin...
