Problems solved by technology

The most common of these is the salinization of the negative plate, which accounts for 90-95% of the failure causes of lead-acid batteries. Although the mechanism of salinization is relatively clear, the existing technology lacks solutions, which is called battery cancer.

Abstract

The invention discloses a lead-acid storage battery repairing liquid and a method for repairing the lead-acid storage battery by using the same, belongs to the field of the lead-acid storage battery, and solves the problems that a failure lead-acid storage battery caused by salinization is difficult to repair. The lead-acid storage battery repairing liquid comprises a catalytic complexing agent, a surfactant, a bulking agent, a sulfate additive and sodium p-toluenesulfonate. The method for repairing the lead-acid storage battery comprises the steps of (1) putting the storage battery in a container, injecting water to the container until a water level is flush with a middle cover of the storage battery, adjusting water temperature and charging the storage battery; (2) subjecting the storage battery to horizontal and vertical frequency wave vibration, taking out the storage battery and injecting the lead-acid storage battery repairing liquid; (3) connecting storage batteries with open circuit voltage differential voltage smaller than 0.3 V into a group in series; (4) charging for a plurality of times in different current, discharging at 2H rate and then charging for a plurality of times in different current; and (5) discharging redundant lead-acid storage battery repairing liquid. The horizontal and vertical frequency wave vibration allows lead sulfate to be smashed; the lead-acid storage battery repairing liquid allows the electrical conductivity of the storage battery to be enhanced and the internal resistance of the storage battery to be reduced; and the capacity of the lead-acid storage battery can be repaired to over 95% that of an original storage battery.

Description

technical field [0001] The invention relates to the field of lead-acid batteries, in particular to a lead-acid battery repair liquid and a method for repairing lead-acid batteries using the solution. Background technique [0002] From the beginning of the use of lead-acid batteries, the general trend is that the capacity of the battery is getting smaller and smaller, and the discharge duration is getting shorter and shorter. When the discharge duration is lower than 60-80% of the design standard, the industry standard judges it as invalid. The reasons for failure can be attributed to four major reasons: water loss, mechanical failure, positive plate material falling off, and negative plate material lead sulfate crystallization and salinization (referred to as salinization). The most common of these is negative plate salinization, which accounts for 90-95% of the failure causes of lead-acid batteries. Although the mechanism of salinization is relatively clear, the existing te...
