Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a lead-acid battery electrolyte, a preparation method thereof and a lead-acid battery. 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] The five major components of a lead-acid battery are the positive electrode, the negative electrode, the diaphragm, the electrolyte, and the battery case, among which the electrolyte is one of the main factors affecting battery performance. Ordinary electrolytes have large internal resistance, poor acid-fixing abilit...
