Problems solved by technology

Some of the above-mentioned technologies are based on changing the structure of lead-acid batteries, which are limited to professional manufacturers and suitable for PE-type separators, which is not conducive to the promotion and popularization of colloidal batteries; acid, and then perfuse colloidal electrolyte. This method is difficult to ensure the stability of the gel, and the process is complicated, which wastes raw materials and man-hours. Due to the long soaking time in sulfuric acid, the plates are damaged, and acid mist is generated to pollute the environment; (or silicon powder) and various additives, although their quality is stable, but the production cycle is long, the output is low, power consumption, complicated process, inconvenient operation, high cost

Abstract

A high-conductivity colloidal electrolyte for lead accumulator is prepared from materials A, B and C through mixing and pouring into accumulator by two stps. Said A contains sulfuric acid, phosphoric acid and cadmium sulfate. Said B and C contain silicon (2.5% and 9% respectively), propanetriol, potassium hydroxide, lithium hydroxide, etc. Its advantages are high capacity, low cost, stable quality, no acid fog pollution, and less loss of self discharge.

Description

Technical field [0001] The invention relates to the preparation of a high-conductivity colloidal electrolyte for pouring lead-acid batteries and its pouring process, belonging to the field of storage battery production. Background technique [0002] At present, there are many researches on colloidal batteries at home and abroad. I applied for the invention patent of 9710790.0 in 1997 with the application number of 9710790.0 "battery non-polluting solid electrolyte and its preparation process". Lead-acid battery, West German patent DE3521200A1, uses dilute sulfuric acid to pour the upper limit of the electrolyte level of the lead-acid battery first, pours out the excess sulfuric acid after soaking in dilute acid for 30 minutes, so that the capacity of each 100Ah in the pores of the plates and separators Keep 1.2 liters of perfused sulfuric acid electrolyte, and then pour thixotropic glue made of dilute sulfuric acid and silicic acid prepared by pyrolysis into the free electroly...
