Abstract

The invention discloses an electrolyte used for an ion state mixed crystal salt storage battery. The electrolyte comprises the following components in percentage by weight: 52-80% of hydrosulphate, 0.1-8% of corrosion inhibitor, 0.4-3% of antiager, 3-12% of strong acid salt agent, 0.1-10% of ester ion concentration control agent, 1-13% of lead-acid storage battery activating agent, 1-10% of chemically pure sulfuric acid of which the concentration is larger than or equal to 98%, and the balance of distilled water. The electrolyte disclosed by the invention has the advantages that the environment pollution caused by sulfuric acid in the electrolyte of the existing lead-acid storage battery is effectively avoided, a system is enabled to have stable and mild reactivity, the stable electrochemical performance of the storage battery is improved, the high and low ambient temperature adaptability is strong, the effective discharge capacity and the self discharge rate are small, and the service life of the battery can be effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of electrolytes for accumulators, and in particular relates to an electrolyte for ionic mixed crystal salt accumulators. Background technique [0002] The electrodes of the existing lead-acid storage batteries are mainly made of lead and its oxides. The electrolyte is a sulfuric acid solution, which belongs to a secondary battery. After being discharged during use, it is recharged, and the battery function can be restored and more repeated use. Over the past 150 years, it has brought great contributions and convenience to the economic development of society and human life. However, due to the large amount of sulfuric acid used in the production process of these existing batteries, they cause serious pollution to the environmental soil and water sources, and when used for high-current discharge, such as the actual mass specific energy of power batteries used in electric vehicles or electric bicycles (WH / kg)...
