Problems solved by technology

[0004] The repair activators and repair methods currently on the market can only solve the problem of lead sulfate crystallization, but cannot solve the problem of electrolyte stratification. That is to say, even if the original function can be restored, its service life cannot be guaranteed

Embodiment 1

[0028] A repairing activator for waste lead-acid batteries, prepared by the following preparation method:

[0029] (1) Add 0.3% polyacryloyl ammonium to deionized water, stir to obtain a gel, add 0.8% fumed silica, and stir to obtain a mother liquor;

[0030] (2) add 60 parts of deionized water in 20 parts of mother liquors, and successively add 4 parts of carbon nanotubes, 5 parts of sodium sulfate, 6 parts of cobalt sulfate, 8 parts of copper sulfate, mix, stir to obtain this waste lead acid Battery repair activator.

Embodiment 2

[0032] A repairing activator for waste lead-acid batteries, prepared by the following preparation method:

[0033] (1) Add 0.8% polyacrylamide to deionized water, stir to obtain a gel, add 2% fumed silica, and stir to obtain a mother liquor;

[0034] (2) add 50 parts of deionized water in 15 parts of mother liquors, and successively add 3 parts of carbon nanotubes, 7 parts of sodium sulfate, 8 parts of cobalt sulfate, 4 parts of copper sulfate, mix, stir to obtain this waste lead acid Battery repair activator.

Embodiment 3

[0036] A repairing activator for waste lead-acid batteries, prepared by the following preparation method:

[0037] (1) Add 0.6% ammonium polyacrylate to deionized water, stir to obtain a gel, add 3% fumed silica, stir to obtain a mother liquor;

[0038] (2) add 70 parts of deionized water in 30 parts of mother liquors, and successively add 5 parts of carbon nanotubes, 4 parts of sodium sulfate, 5 parts of cobalt sulfate, 9 parts of copper sulfate, mix and stir to obtain this waste lead acid Battery repair activator.

Abstract

The invention discloses a waste lead-acid storage battery repair activator and a preparation method thereof. The activator is prepared from 15-30 parts by weight of mother liquor, 3-5 parts by weightof carbon nano tubes, 4-7 parts by weight of sodium sulfate, 5-8 parts by weight of cobalt sulfate, 4-9 parts by weight of copper sulfate and 50-70 parts by weight of deionized water, wherein the mother liquor is prepared from 0.2-0.8 wt% of super absorbent resin, 0.5-3 wt% of fumed silica and the balance of deionized water. According to the waste lead-acid storage battery repair activator, decomposition of originally non-conductive lead sulfate is accelerated, it is guaranteed that the temperature of the storage battery is not excessively increased when high-frequency current is activated, the storage battery is effectively protected, and due to the fact that the activating agent is made of super absorbent resin according to the multi-encapsulation theory, electrolyte molecules are wrapped with one another, and the layering phenomenon is not likely to happen.

Description

technical field [0001] The invention belongs to the field of recycling waste batteries, in particular to a repair activator for waste lead-acid batteries and a preparation method thereof. Background technique [0002] China is one of the largest production and sales countries of lead-acid batteries in the world. Lead-acid batteries, as the most important stable power supply and DC power supply, have a long history and are widely used. They are active in various industries such as telecommunications, electric power, finance, automobiles, railways, ships, radio and television, solar energy, wind energy, national defense, etc. Especially with the rapid development of the automobile and electric bicycle industries, lead-acid batteries are widely used At the same time, the problem of battery scrapping has become a focus of concern for governments and users of various countries. In western developed countries, there are strict regulations on the use and recycling of lead-acid bat...
