Electrolyte of colloidal battery

Abstract

The invention relates to the technical field of electrolytes, in particular to an electrolyte of a colloidal battery. The electrolyte of the colloidal battery is characterized by comprising the following components in parts by weight: 2-5 parts of fumed SiO2, 0.2-0.4 part of polyacrylamide, 2-4 parts of glycerin, 0.5-3 parts of H3PO4, 0.5-2.5 parts of anhydrous sodium sulfate, 34-38 parts of sulfuric acid, 0.5-0.8 part of EDTA, 0.1-0.5 part of aluminum hydroxide, 0.5-1 part of a propanetriol solution and the balance of water. In the electrolyte, the propanetriol solution is added, so that a moisturizing function is enhanced, and thus the cycle life of the colloidal battery under a high-temperature condition is prolonged; in addition, through the fumed SiO2 hydrosol, after addition of the sulfuric acid, the colloidal storage battery is stable in performance and good in thixotropic property, and electrochemical performance indexes of the storage battery are met.

Description

technical field [0001] The invention relates to the technical field of electrolytes, in particular to a colloidal battery electrolyte. Background technique [0002] Gel batteries belong to a development category of lead-acid batteries. The method is to add a gelling agent to sulfuric acid to make the sulfuric acid electrolyte into a colloidal state. A battery in which the electro-hydraulic is in a colloidal state is usually called a colloidal battery. The difference between gel batteries and conventional lead-acid batteries is from the initial understanding of electrolyte gelation, to the research on the electrochemical characteristics of the electrolyte basic structure, and the application and promotion of grids and active materials. Its most important feature is: use less industrial cost to manufacture better quality batteries, its discharge curve is straight, its inflection point is high, its energy and power are more than 20% larger than conventional lead-acid batteries...

AI Technical Summary

Problems solved by technology

Of course, there are various factors affecting it. One of the important reasons is that the electrolyte of the existing colloidal battery has a poor moisturizing function, which leads to the gradual decrease of the moisture inside the battery in a high temperature environment, thereby gradually reducing the affinity between the electrolyte and the surface of the plate. , the contact internal resistance gradually increases, leading to battery failure
