Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to a storage battery electrolyte and a storage 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] Lead-acid batteries have been widely used in various fields, especially in the field of telecommunications, backup power supply, energy storage power supply and power applications, etc. However, traditional lead-acid batteries also have a series of problems such as early capacity decay and short service life. The symptoms are Corrosion of the positive ...
