AI Technical Summary

Problems solved by technology

There are serious technical defects in this method of repairing batteries, mainly: 1. Only superficial and partial removal of sulfuric acid crystals; 2. Damage to battery plates; 3. Cannot reduce lead sulfate crystals to dilute sulfuric acid; 4. , The battery plate will continue to crystallize, and the performance of the repaired battery will soon decline
Since it does not really repair the battery, this technology cannot be promoted.
Before the technology of the present invention, there is no technology or method that can effectively remove the lead sulfate crystals on the battery pole plate

Embodiment Construction

[0023] For further elaborating the technical means and effects that the present invention takes to reach the intended invention purpose, below in conjunction with preferred embodiment, to its specific implementation, structure, feature and effect of the lead-acid battery repair solution that proposes according to the present invention, detail The description is as follows.

[0024] Technical principle of the present invention:

[0025] Due to the existence of ethylenically unsaturated groups and hydroxyl groups in the polymer organic material in the formula, a part of the hydroxyl groups is adsorbed on the hydrophilic PbSO4 solid particles, and the other part of the hydrophilic hydroxyl groups is dispersed in the aqueous solution to form a stable dispersion system without Coalescence, that is, maintaining the number of particles per unit volume basically unchanged, while increasing the viscosity of the medium, manifested as a significant increase in system stability. As stabi...

Abstract

The invention relates to a lead-acid storage battery repair fluid and a preparation method thereof. The lead-acid storage battery repair fluid comprises, by mass, 95%-98% of deionized water, 0.5%-2.5%of nanometer silicon nitride powder, 0.3%-0.8% of polyethylene glycol, 0.3%-0.8% of polyvinyl alcohol, 0.3%-0.8% of sodium polyacrylate, 0.3%-0.8% of polyvinylamide and 0.03%-0.2% of salicylic acid.The lead-acid storage battery repair fluid can effectively dissolve to remove lead sulfate crystals on the battery plate, recover the battery plate functions, repair the lead-acid storage battery losing efficacy because of sulfation and prolong the service life of the battery.

Description

technical field [0001] The technology of the invention belongs to the technical field of electrochemistry. The technical product of the invention is: a lead-acid battery repair liquid product and a repair method. Products involved in the repair of lead-acid batteries. Background technique [0002] As the most important stable power supply and DC power supply, lead-acid batteries are widely used in various industries and departments such as aviation, railways, automobiles, ships, communications, finance, and national defense. Among all kinds of batteries, lead-acid batteries account for the largest proportion, about 75% of the total batteries. At present, the social use of lead-acid batteries in my country is more than 300 million, and it is still increasing rapidly in recent years. [0003] After the lead-acid battery has been used for a certain period of time (generally about two years), or due to improper use (battery undercharge, overcharge, overdischarge, long-term st...
