Abstract
The invention provides a repairing reducing agent for lead-acid storage batteries, which can dissolve lead sulfate crystals deposited on polar plates. Metal ions are not introduced in, so that the self discharge of the metal ions and the softening of the polar plates can be avoided. The physical structure of the batteries is not destroyed, the chemical environment of the batteries is not changed and an organic protective film can be formed on the surface of the polar plates of the batteries to restrain the deposition of newly-generated lead sulfate crystals and ensure the long-term action and the stability of repair effects. A nanometer graphene oxide material which is beneficial for increasing the specific surface area of electrodes, improving the surface structure of the electrodes, lowering the internal resistance and improving the transfer efficiency of interface electrons is introduced in. The electric conductance of electrolyte is enhanced, the internal resistance of the batteries is lowered, and the capacity restorability and the recharging receptivity after the overdischarge of the storage batteries are improved. The battery capacity can be restored to the maximum degree and the service life of the batteries is prolonged. The capability of the repaired storage batteries can be restored to more than 90% and the service life of the repaired storage batteries can be prolonged by double or more.
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 are widely used in industry, transportation, automobile, communication, electric power and other industries. Its designed service life is generally 3 to 8 years. However, due to the influence of factors such as the use environment, battery performance, maintenance technology, and personnel quality, the actual service life is far lower than the design life, mainly manifested in rapid decline in battery capacity, shortened service life, monomer consistency, and charge and discharge capabilities. Unsatisfactory, etc., seriously affect various power supply guarantees and greatly increase maintenance and operating costs. According to statistics, a considerable part of the premature failure of lead-acid batteries is caused by the vulcanization of the battery plates. Un...
