Problems solved by technology

The physical activation method is simple to operate, but the operation time is long, and it has high requirements for the activation equipment and operating conditions. At the same time, because the activation pulse repair frequency is single, it can repair crystal particles within a certain range, and cannot repair all the crystal particles in the lead-acid battery. repaired, with certain limitations
The repair effect of chemical activation method is ideal, with the advantages of quick effect and outstanding effect, but it may need to disassemble and repair the battery. In addition, the addition of activator may increase the internal resistance of the battery, change the original structure of the electrolyte, and the secondary life after repair is relatively short. short

Abstract

The invention provides a flexible activating agent of a lead-acid storage battery and a preparation method of the flexible activating agent, and solves the problems that the activating agent of the lead-acid storage battery in the prior art is single in repairing effect and easy to damage the battery. The flexible activating agent is prepared from the following raw materials: polyvinyl alcohol, fumed silica, aquatic creature mercaptan, a nano carbon material and sulfate. In addition, the invention also provides a repair method of the retired lead-acid storage battery, which comprises the following specific steps: firstly, carrying out discharge treatment on the retired lead-acid storage battery without physical damage, adding 0.3-1.5 mL of the flexible activator per Ah per monomer, standing, and then, carrying out charge activation on the retired lead-acid storage battery. The repaired retired lead-acid storage battery is high in capacity recovery rate, has the effect of delaying sulfation, is safe and reliable, and has no adverse effect on human bodies and the environment.

Description

technical field [0001] The invention belongs to the technical field of battery activation, and in particular relates to a flexible activator for lead-acid batteries, a preparation method thereof, and an activation method for decommissioned lead-acid batteries. Background technique [0002] Lead-acid batteries have the advantages of low price, safe and stable operation, etc., and are widely used in energy storage batteries, communication backup power batteries, automobile starting batteries and traction batteries, etc. The design life of lead-acid batteries is generally 8 to 10 years, but the actual situation There is a phenomenon of premature decommissioning before the design life is reached. At present, waste lead-acid batteries have been included in the national "Hazardous Waste List" management, and the decommissioned batteries will become hazardous waste in a short period of time after simple cascade utilization. A huge number of waste lead-acid batteries will result in ...
