Abstract

The invention discloses an online activation method for a lead-acid storage battery and belongs to the technical field of storage battery recycling. The method is characterized by comprising the activation steps of: checking the storage battery, injecting glacial acetic acid into an electrolyte solution of the storage battery, sealing the storage battery, and over-discharging the storage battery until the voltage of the storage battery is 0V; opening the storage battery again, injecting an active agent, and adding distilled water into the storage battery until the rated electrolyte solution capacity of the storage battery is reached, wherein the total additive amount of the active agent is 0.45-0.65% of the total mass of the electrolyte solution; and sealing the storage battery again and charging the storage battery until the original rated voltage of the storage battery is reached. According to the activation method, not only can a scraped lead-acid storage battery with the battery capacity lower than a rated value be repaired but also a new battery or a slightly vulcanized lead-acid storage battery can be directly activated, and the service life of the battery can be greatly prolonged after the activation.

Description

technical field [0001] The invention discloses an online activation method of a lead-acid storage battery, which belongs to the technical field of storage battery reuse. Background technique [0002] In long-term practice, people have used many methods to eliminate the vulcanization of the battery plate to prolong the service life of the battery, which can be summarized as follows: [0003] 1. High-current charging: use high-current charging to dissolve large lead sulfate crystals. It is found in experiments that this method can only obtain temporary effects in eliminating vulcanization, and will cause aggravated dehydration and The problem of softening of the positive plate has caused serious damage to the battery life, and now few people use this simple method to repair the battery. [0004] 2. Full charge and full discharge repair method: The full charge and full discharge repair method is a method of repairing the battery after it is fully charged and then fully dischar...
