Problems solved by technology

Under normal use conditions, the lead-acid battery should not be over-discharged, otherwise the fine lead sulfate crystals mixed with the active material will form a larger body, which not only increases the resistance of the plate, but also makes it difficult to make it regenerate when charging. Reduction, directly affects the capacity and life of the battery
The design life of lead-acid batteries is generally 5-8 years, but in actual use, the capacity of lead-acid batteries will be significantly reduced after 1-2 years of use, which will bring great inconvenience and trouble to users
Although there are also lead-acid battery repair agents or specific methods for repair in the prior art, the repair effect is not ideal

Abstract

The invention belongs to the technical field of lead storage batteries, and particularly relates to a lead storage battery repairing agent and a repairing method. The lead storage battery repairing agent is prepared from the following raw materials in parts by weight: 10-15 parts of ammonium acetate, 0.1-3 part of graphene, 2-5 parts of mercaptoethanol, 1-10 parts of ferrous sulfate, 3-8 parts ofethylenediamine tetraacetic acid disodium salt, 0.01-0.05 part of gellan gum, 1-5 parts of copper sulfate and 20-45 parts of sulfuric acid solution. The lead storage battery repairing agent can significantly improve the battery capacity.

Description

technical field [0001] The invention belongs to the technical field of lead storage batteries, and in particular relates to a repairing agent for lead storage batteries and a repairing method. Background technique [0002] In addition to lithium batteries, commonly used rechargeable batteries, lead-acid batteries are also a very important battery system. The advantage of lead-acid batteries is that the electromotive force is relatively stable during discharge, but the disadvantage is that the specific energy (electric energy stored per unit weight) is small and it is highly corrosive to the environment. Lead-acid batteries have stable working voltage, wide range of operating temperature and operating current, can charge and discharge hundreds of cycles, good storage performance (especially suitable for dry charging storage), and low cost, so they are widely used. [0003] With the discharge of the battery, both the positive and negative plates are vulcanized, and the sulfur...
