AI Technical Summary

Problems solved by technology

However, this type of repair agent also dissolves lead, reduces the mechanical strength of the plate, and accelerates the active material on the plate to fall off
In addition, hydrophilic functional polymer materials can also be added, which have a strong ability to spread and penetrate solid surface substances. After being injected into the interior of the lead-acid battery, they can be quickly dispersed through the internal sulfuric acid liquid system. The functional groups of the polymer chain and the negative plate The lead sulfate crystal clusters on the surface interact with each other. As a result, the salinized clusters on the negative plate are gradually disintegrated, and the barrier effect of the surface layer is destroyed. The battery capacity can be restored by recharging the battery, but this method has It may increase the internal resistance of the battery, resulting in a shorter service life after repair

Abstract

The invention provides a repairing reducing agent for a lead-acid storage battery. Lead sulfate crystal deposited on an electrode plate can be dissolved. No metal ion is introduced, so that self-discharge of the metal ion and softening of the electrode plate can be avoided; a physical structure of the battery is not destroyed; the chemical environment of the battery is not changed; an organic protection film can be formed on the surface of the electrode plate of the battery; deposition of newly generated lead sulfate crystal is inhibited; and long-acting and stable repairing effect can be ensured. A nano oxidized graphene material is introduced, so that improvement of the specific surface area of an electrode is facilitated; the electrode surface structure is improved; the internal resistance is reduced; the interfacial electron transfer efficiency is improved; the conductivity of an electrolyte is strengthened; the internal resistance of the battery is reduced; the capacity recovery performance and the recharge acceptance of the storage battery after being over-discharged are improved; the capacity of the battery can be restored to the maximal extent; the service lifetime of the battery is prolonged; the capacity of the repaired storage battery can be restored to over 90%; and the service lifetime can be doubled or above.

Description

technical field [0001] The invention belongs to the technical field of battery repair, and in particular relates to a reducing agent for lead-acid battery repair. Background technique [0002] Lead-acid batteries have a wide range of applications. Due to the impact of the use environment and battery performance, the battery capacity of lead-acid batteries decreases rapidly, the service life is shortened, the consistency of the monomers, and the charging and discharging capabilities are not ideal, which seriously affects various power supplies and greatly increases maintenance and operating costs. According to statistics, a considerable part of the premature failure of lead-acid batteries is caused by the vulcanization of battery plates. Therefore, it is urgently needed in the industry to provide a lead-acid battery repair technology that can overcome battery vulcanization and maintain consistency. [0003] At present, the main repair technology of lead-acid batteries includ...
