Embodiment 1

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

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

[0030] (2) Add 60 parts of deionized water to 20 parts of mother liquor, and successively add 4 parts of carbon nanotubes, 5 parts of sodium sulfate, 6 parts of cobalt sulfate, and 8 parts of copper sulfate, mix and stir to obtain the 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 evenly to obtain a mother liquor;

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

Embodiment 3

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

Abstract

The invention discloses an activator for repairing waste lead-acid batteries and a preparation method thereof. The activator comprises 15-30 parts by weight of mother liquor, 3-5 parts by weight of carbon nanotubes, 4-7 parts by weight of sodium sulfate, and 5 parts by weight of cobalt sulfate. ‑8 parts by weight, 4‑9 parts by weight of copper sulfate, and 50‑70 parts by weight of deionized water, wherein the mother liquor includes 0.2‑0.8 weight percent superabsorbent resin, 0.5‑3 weight percent fumed silica and the rest Measure deionized water. The repair activator for waste lead-acid batteries of the present invention, on the one hand, accelerates the decomposition of the originally non-conductive lead sulfate; The activator is made of super absorbent resin according to the multi-encapsulation theory, so that the electrolyte molecules are wrapped around each other and it is not easy to cause delamination.

Description

technical field [0001] The invention belongs to the field of recovery and reuse of waste batteries, and in particular relates 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, radio and television, solar energy, wind energy, and national defense. Especially with the rapid development of the automobile and electric bicycle industries, lead-acid batteries are being used in large quantities. , The problem of battery scrapping has become the focus of governments and users. In western developed countries, there are strict regulations on the use and recycling of lead-acid batteries. The...
