Abstract

The invention belongs to the technical field of lead-acid storage batteries and in particular relates to a preparation method of lead-acid storage battery gel electrolyte, aiming at solving the problems in the prior art that gel electrolyte has a serious hydration and layering phenomenon, great resistance and short service life. The preparation method comprises the following steps: after mixing nano silicon dioxide and distilled water, dispersing; then adding methyltrimethoxysilane, and raising the temperature and reacting to obtain a mixed solution A; stirring and mixing sulfate, nano boron oxide, 1-allyl-3-methylimidazole chloride, sodium alcohol ether sulphate and the residual distilled water to obtain a solution B; adding dimethicone, lubricating grease and sulfuric acid into the mixedsolution B and mixing to obtain a mixed solution C; after mixing the mixed solution A and the mixed solution C, adding a stabilizing agent and uniformly mixing to obtain the lead-acid storage batterygel electrolyte. The preparation method provided by the invention has the advantages of simplicity, moderate preparation conditions and low cost; the prepared gel electrolyte has good thixotropic behaviors, small inner resistance, no acid leakage, no smoke, slow water loss speed and long service life and is worthy of being popularized.

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...
