A method for preparing colloidal electrolyte with gum arabic as stabilizer

Abstract

The invention discloses a method for preparation of gel electrolyte with Arabic gum as the stabilizing agent. The method includes: firstly weighing silicon dioxide, sodium sulfate and stannous sulfate, adding the three substances into water and performing shearing dispersion to obtain a silicon dioxide suspension containing sodium sulfate and stannous sulfate; then weighing a sulfuric acid solution, adding Arabic gum to perform shearing dispersion, thus obtaining an Arabic gum sulfuric acid solution; and finally subjecting the obtained silicon dioxide suspension and the Arabic gum sulfuric acid solution to shearing mixing, thus obtaining the silicon dioxide / sulfuric acid gel electrolyte product. The silicon dioxide / sulfuric acid gel electrolyte prepared by the method provided by the invention has the characteristics of stable performance and long gelation time, and is in favor of electrolyte injection.

Description

technical field [0001] The invention relates to the technical field of battery electrolytes, in particular to a method for preparing colloidal electrolytes using gum arabic as a stabilizer. Background technique [0002] Since the lead-acid battery was invented in 1958, it has a history of more than 100 years. Lead-acid batteries have the advantages of simple structure, reliable performance, convenient use, easy access to raw materials and low price. They are widely used in many fields of national economy such as transportation, communication and national defense, and have become indispensable in social production and human life. energy products. [0003] Lead-acid batteries have been widely used in various fields, especially in the field of telecommunications, backup power, energy storage power and power applications, etc., but traditional lead-acid batteries also have a series of problems such as early capacity decay and short service life. [0004] At present, traditiona...

Problems solved by technology

[0003] Lead-acid batteries have been widely used in various fields, especially in the field of telecommunications, backup power, energy storage power and power applications, etc., but traditional lead-acid batteries also have a series of problems such as early capacity decay and short service life.

[0004] At present, the traditional lead-acid battery uses sulfuric acid as the electrolyte, and the sulfation of the plate will occur during the production process. At the same time, the self-discharge is large, the low-temperature performance is poor, and the service life is short.
