Abstract

The invention discloses a storage battery electrolyte and a storage battery. The storage battery electrolyte comprises sulfuric acid, stannous mono-sulphate, ammonium sulfate, sodium sulfate, 4, 5-diethyl vinylene carbonate, 4-methyl-5-propyl vinylene carbonate, phenylcyclohexane, anisole, modified polyacrylamide, disodium EDTA, 2, 6-di-tert-butyl-4-methylphenol, 1 (H)-2-p-chlorobenzyl benzimidazole, a sulfone additive, 2,4,6-trimercapto-s-triazine trisodium salt solution, nano-scale silicon dioxide and deionized water. The defects in the prior art can be overcome, the use frequency and the service life of the storage battery can be remarkably improved, and meanwhile, the storage battery is good in stability and easy to popularize and use.

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 ...
