Process for filling colloid into storage battery

Abstract

The invention discloses a process for filling colloid into a storage battery. The process comprises the following steps of: a) exchanging heat, namely, performing heat exchange on a colloidal electrolyte until the temperature of the colloidal electrolyte is between 0 and 45 DEG C and preserving heat; b, shearing, namely, shearing the colloidal electrolyte by using a shearing machine; and c) vacuumizing and filling, namely, vacuumizing the storage battery for 1 to 5 times and filling the sheared colloidal electrolyte into the storage battery. The colloidal electrolyte is subjected to heat exchange until a preset temperature is reached and then sheared by a stator grid, the viscosity of the colloidal electrolyte is reduced to an appropriate colloid filling range and the sheared colloidal electrolyte is quantitatively filled into the storage battery through a vacuumizing system. The performance of the storage battery is improved, electrolyte stirring time is short and a filling process is rapid and convenient.

Description

【Technical field】 [0001] The invention relates to the perfusion of accumulator electrolytes, in particular to the perfusion process of colloidal electrolytes for colloidal batteries. 【Background technique】 [0002] At present, there are two main ways to pour the colloidal electrolyte of the battery into the battery. One is to mix and dilute silicon dioxide and sulfuric acid electrolyte to make a colloidal electrolyte and directly pour it into the battery, commonly known as the direct perfusion method; The sulfuric acid is added to the battery first, and then the silica hydrosol is added after some processing, commonly known as the acid first and then the glue method. The traditional direct perfusion method requires the electrolyte to gel for a long enough time, because it takes a long time to disperse silica with a stirrer, and the amount of colloidal electrolyte dispersed each time needs to be relatively large, enough to perfuse multiple batteries. The traditional direct p...

AI Technical Summary

Problems solved by technology

The traditional direct perfusion method requires low silica content, and the electrolyte is easy to gel during the perfusion process, affecting battery capacity and uniformity

The method of acid first and then glue is a flexible glue filling process as a last resort. It is difficult to control the uniformity of water glue poured into the battery and the dispersion of sulfuric acid electrolyte.
