Abstract

The invention discloses a preparation method for a charging-resistant electrolyte of a storage battery. The electrolyte comprises the following components: 30-50 parts of sulfuric acid, 1-2 parts of polyacrylamide, 0.1-0.5 parts of polytetrafluoroethylene emulsion, 0.05-0.15 parts of polyethylene emulsion, 0.2-0.5 parts of polyethylene glycol, 5-8 parts of tolyltriazole, 5-8 parts of 2-mercapto benzimidazole diallyl sulfide, 2-5 parts of trifluoromethanesulfonate, 2-5 parts of hydrosulphate, 3-5 parts of methyl acetate, 3-5 parts of butyl propanoate, and 80-100 parts of deionized water. The electrolyte prepared by the invention has the advantages of charging resistance, high temperature and low temperature resistance, and long service life.

Description

technical field [0001] The invention relates to the technical field of accumulators, in particular to a method for preparing a charge-resistant accumulator electrolyte. 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] Due to its low price and mature technology, lead-acid batteries are now widely used. Although many new batteries have begun to appear, lead-acid batteries still have an irreplaceable position in many fields. The five major components of a lead-acid battery are the positive electrode, the negative electrode, the diaphragm, the electrolyte, and ...
