Abstract

The present application provides a battery regeneration liquid, a regeneration method and application thereof. The battery regeneration liquid provided herein contains stannous organic acid. Stannousorganic acid can react with inactivated PbSO4 in acidic condition, and then reactivate the inactivated PbSO4, and dissociate into Pb<2+> and SO<4><2->, completing the charging process and realizing the regeneration of lead-acid battery. According to the battery regeneration solution containing stannous organic acid and the regeneration method provided by the present application, the battery capacity of the lead-acid battery with early capacity degradation can be restored to 93.2% of the nominal capacity, and the battery capacity of the lead-acid battery with early capacity degradation can be restored to 93.2%-96% of the nominal capacity, reaching the use requirement that the battery capacity is 80% of the nominal capacity. The regeneration of lead-acid battery not only improves the utilization rate of lead paste, but also improves the economic benefit, social benefit and environmental protection benefit.

Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to a storage battery regeneration liquid, a regeneration method and an application. Background technique [0002] Lead-acid battery is a commonly used battery. Its electrodes are made of lead and its oxides, and its electrolyte is composed of sulfuric acid solution. Lead-acid batteries have the characteristics of high safety, good reliability, low cost and wide working range. Therefore, lead-acid batteries are an important secondary power source. [0003] After the lead-acid battery is used for a period of time, the battery capacity decays, resulting in its use time not reaching half of the design life. At the same time, due to the difference in the manufacturing process, the actual battery capacity of each lead-acid battery is different, and the attenuation degree of the battery capacity is different. When the battery capacity of the lead-acid battery decays to a certai...
