Vulcanization-induced failed lead-acid storage battery repair method

Abstract

The invention relates to a lead-acid storage battery repair method, in particular to a vulcanization-induced failed lead-acid storage battery repair method. The vulcanization-induced failed lead-acid storage battery repair method is characterized in that the method comprises the following steps of: visually inspecting a fault, detecting, precharging, judging whether polar plate active matters become slurry or not, filling in dilute acid or repaid liquid, statically placing the battery, recording initial capacity, recording discharge time and over-discharge time, determining repaid charge capacity and a charge and discharge process flow, and repairing according to different battery capacities. Through the steps, the vulcanization-induced failed lead-acid storage battery repair method fundamentally solves the problem that lead sulfate is crystallized, not only can the vulcanization removal rate be reach more than 90 percent, but also the repaid success rate of the battery failed because of vulcanization can reach more than 95 percent, the service life of the battery is prolonged by more than 80 percent, the polar plate lead sulfate crystals which are though to be inevitable by the traditional theory are dissolved, and the capacities of most lead-acid storage batteries can be restored and the lead-acid storage batteries can be reused as long as the waste batteries are not visually damaged and deformed and do not have hard faults.

Description

technical field

[0001] The invention relates to a repair method for a lead-acid battery, in particular to a repair method for a lead-acid battery based on vulcanization failure. Background technique

[0002] Lead-acid batteries have always been the industry leader in chemical energy, accounting for more than 95% of the total battery power in the market so far. However, lead-acid batteries have the fatal weakness of short service life, and lead sulfate crystallization salinization (often called vulcanization) and active material slurry are the main reasons for this fatal weakness. Among them, the shortened lifespan due to lead sulfate crystallization accounts for more than 80%, which is even called "lead battery cancer" in the industry. However, for this fault, it can be repaired to a certain extent by desulfurization method, but it cannot be repaired for hard faults such as active material slurry and battery short circuit and open circuit.
