Abstract

The invention relates to an storage battery colloid electrolyte, which comprises a deionized water, a polyacrylamide solution, Tin (II) Sulfate solution, a gas phase SiO2 and a glycerin, which has the weight ratio that the deionized water: the polyacrylamide solution : Tin (II) Sulfate solution : gas phase SiO2 : glycerin =100:0.5-1:0.4-1:15-21:0.3-0.7; the polyacrylamide solution is the mixing solution of an analysis pure polyacylamide solution and the deionized water according to the weight ratio of 0.5-1:100; the Tin(II) sulfate solution is the suspension turbid liquid mixed by the analysis pure Tin(II) sulfate solution and the deionized water according to the weight ratio 1-2:10, which solves the problem such as the colloid hydration. The invention also provides an adhesive injection process of battery assembly adopting the colloid electrolyte; the adhesive is injected after the acid is added, so that the colloid can not be solidified, and the adhesive injection is easy, which avoids the problem that the battery is heated, especially that the inside and the bottom of the battery are not easy to inject the adhesive.

Description

technical field [0001] The invention relates to a storage battery electrolyte, in particular to a colloidal electrolyte, and a lead-acid storage battery assembly and glue process using the colloidal electrolyte. Background technique [0002] The performance of colloidal batteries mostly depends on the performance of the electrolyte and the method of adding glue, and the colloidal electrolyte is generally made of SiO 2 , sulfuric acid, water and additives to form a gel system. For a long time, colloidal electrolytes have problems such as low silica content, poor stability, and poor acid-fixing ability leading to unstable gel strength, which seriously affects the performance of colloidal batteries, especially in the way of colloidal perfusion, pole In terms of internal or gel uniformity and gel state, the capacitance of the gel battery is 10%-20% lower than that of the AGM battery of the same specification. The battery heats up during the process of adding glue, and it is di...
