Abstract

The invention discloses a storage battery electrolyte with high electrochemical performance, which is prepared from, by mass, 40-60 parts of hydrogen sulfate, 10-20 parts of stannous sulfate, 10-20 parts of phosphoric acid, 0.2-0.4 part of cobalt acetate, 1-2 parts of phosphonic acid, 0.5-1 part of EDTA disodium, and 0.5-1 part of 2-mercaptobenzimidazole allyl sulfide, 3-5 parts of methyl sulfonate, 3-5 parts of trifluoromethyl sulfate, 8-10 parts of ethyl acetate, 8-10 parts of butyl formate and 50-80 parts of deionized water. The storage battery prepared by the electrolyte can obviously improve the service efficiency of the storage battery, and can effectively prolong the service life of the storage battery and is simple and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to a storage battery electrolyte with high electrochemical performance. 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 electrolyt...
