Abstract

Formula of the restoring agent includes following materials and mass percent: potassium sulfate 3-9%; sodium sulfate 4-8%; potassium bicarbonate 0.5-2%; potassium carbonate 1-3%; sodium silicate 0.2-0.8%; potassium acid phthalate 0.015-0.06%; aluminum powder 0.005-0.02 etc and deionized water as surplus. Using quite active metallic ions in the restoring agent to replace quite inert lead ions in crystal of lead sulfate, the method ionizes and hydrolyzes lead sulfate to the sulfate ions and lead ions, which take part in normal electrochemical reaction of lead acid battery again. At the same time, matter in the restoring agent together with quite active metallic ions, which accomplishes replacement, forms stable salt so as to reduce self-discharge inside battery caused by harmful metal ions to retain capacity for long time. The invention restores capacity of accumulator effectively, and lightens environmental pollution from old accumulators.

Description

technical field [0001] The invention belongs to the technical field of storage battery repair. It particularly relates to a lead-acid storage battery vulcanization restoration agent. Background technique [0002] Lead-acid batteries will always be scrapped in advance during use. Although there are many reasons for this, most of them are caused by the "irreversible sulfation" reaction of the battery. At present, the methods of repairing lead-acid batteries after vulcanization failure during use at home and abroad can be mainly divided into two categories: physical methods and chemical methods. [0003] Physical repair methods mainly include: high-current charging method, hydrotherapy, pulse repair, etc. These methods are only effective when the battery is not seriously vulcanized and take a long time, which cannot meet actual needs. People gradually realized the importance of using chemical methods. [0004] The chemical method has a better effect than the repair agent dev...
