Problems solved by technology

[0002] The existing colloidal batteries made of common colloidal materials have obvious disadvantages, that is, due to the problem of the viscosity of the colloidal electrolyte, it is quite difficult to add acid, and the charging will not turn on in the middle and late stages of use, or the battery will heat up and deform ( thermal runaway) etc.
In addition, in ordinary colloidal batteries, only the condition of the electrolyte is changed, and the problem of the plate is not changed to a certain extent, so that the life of the battery in the later period of use is determined by the battery plate

Abstract

The invention discloses a special gel for preparing gel battery. The special gel is composed of the following components (by weight percentage): SiO2 5% to 20%, a stabilizing agent 0.5% to 5%, Na2SO4 3% to 10%, SnSO4 0.2% to 2%, Bi2O3 0.2% to 5% and deionized water in balancing amount. The special gel for the gel battery can effectively prevent layering of sulfuric acid, so as to reduce the acid addition difficulty, reduce the production time, improve the charge acceptance, prolong the service life of electrode plates, and obviate thermal runaway during use of the gel battery in the prior art.

Description

Technical field [0001] The invention relates to a special colloid used in the production of colloidal batteries. Background technique [0002] The existing colloidal batteries made of ordinary colloidal materials have obvious disadvantages, which are due to the problem of the viscosity of the colloidal electrolyte, which makes it difficult to add acid. In the middle and late stages of use, the battery will not turn on the light or the battery will be deformed ( Thermal runaway) and other issues. In addition, in ordinary gel batteries, only the electrolyte is changed, and there is no problem of changing the plate to a certain extent, so that the life of the battery in the later period of use is determined by the battery plate. Summary of the invention [0003] What the present invention aims to solve is to provide a special colloid for the preparation of colloidal batteries. The application of the special colloid for colloidal batteries can effectively prevent sulfuric acid delam...
