Waste lead storage battery repair and activation method

Abstract

The invention relates to the field of recycling and reusing of waste lead storage batteries, in particular to a waste lead storage battery repair and activation method. Aimed at solving the problems existing in the prior art, appearance inspection, instrument testing, primary charging and discharging detection, and original capacity inspection are performed at first; then a repair and activation agent is added, an activation instrument adopts specific high-frequency impulse current to perform repair and activation as well as excitation, a discharging instrument is used to discharge the activated battery for capacity inspection, and discharging further simultaneously promotes the penetration of effective ingredients of the repair and activation agent into the battery; finally, self-discharging detection, battery enclosing, charging and discharging simulation and the like are performed, irreversible sulfate crystals on a pole plate of the storage battery are better cleaned away and avoided, the contact area of an active substance of the pole plate with an electrolyte is greatly enlarged, the function degeneration phenomenon of the waste storage battery is recovered to be higher than 86% of original functions, and the service life of the storage battery is prolonged by more than one time.

Description

technical field [0001] The invention relates to the field of recovery and reuse of waste lead-acid batteries, in particular to a method for repairing and activating waste lead-acid batteries. Background technique [0002] Lead-acid battery, as the most important stable power source and DC power source, has a long history and is widely used. They are active in various industries such as telecommunications, electric power, finance, automobiles, railways, radio and television, solar energy, wind energy, and national defense. Especially with the rapid development of the automobile and electric bicycle industries. While lead-acid batteries are being used in large quantities, the problem of battery scrapping has become a focus of concern for governments and users of various countries. Western developed countries have strict regulations on the use and recycling of lead-acid batteries. The government encourages users to use new technologies to extend battery life. The repair and ...

Problems solved by technology

This lead sulfate crystal is non-conductive and difficult to decompose under conventional charging methods. This phenomenon is called "irreversible sulfation", which causes the internal resistance of the battery to increase and the capacity to decrease. The main reason for its formation is sulfuric acid. The recrystallization phenomenon of lead, which leads to the reduction of solubility after the formation of coarse crystals and the inability to decompose

[0006] At present, domestic and foreign lead-acid batteries are mainly repaired after the capacity is reduced in the early stage of vulcanization during use: high-current charging method, hydrotherapy, pulse repair, etc., but these methods take too long for the lead-acid batteries that have It takes as long as a week or even a month at a time, or the effect is not obvious, and more importantly, the waste lead-acid battery has not been systematically, accurately, and detailedly inspected and judged before being repaired, and it is repaired blindly. It often leads to unsatisfactory repair effect and high repair cost
