Problems solved by technology

However, the problem with this technology is that a single porous carbon material cannot automatically and effectively adsorb Pb during battery charging and discharging. 2+ , the adsorption on the surface cannot deeply utilize the pores inside the porous carbon, which greatly limits the improvement of the performance of the lead-acid battery
[0006] The existing lead-acid battery repair has the following defects: low repair degree, long repair time, and short discharge time after repair, etc.

Embodiment 1

[0035] Example 1 Nano activator SiW 11 Preparation method of @ZIF-8:

[0036] 1. Precursor K 8 [SiW 11 o 39 ]∙14H 2 O (abbreviated as SiW 11 ) Synthesis:

[0037] Dissolve 18.2 g of sodium tungstate in 30 mL of water, and add 16.5 mL of HCl (4 mol∙L -1 ). Then add 10 mL sodium silicate aqueous solution (containing 1.1 g sodium silicate) to the above solution, pass through 4 mol∙L -1 Adjust the pH of the solution to 5-6 with hydrochloric acid (the amount of hydrochloric acid added is about 4 mL). After continuing to stir for 100 min, 9 g of potassium chloride was added, and after continuing to stir for 15 min, the crude product was obtained by filtration.

[0038] Dissolve the crude product in 85mL of water, filter to remove insoluble matter, then add 8g of potassium chloride to the filtrate, filter the resulting white solid with suction, and use 2 mol∙L -1 Potassium chloride 10mL was washed twice, and air-dried; the purified product SiW was obtained 11 , the purifie...
