Abstract

The invention discloses a biomacromolecule repairing agent for a lead-acid storage battery. The biomacromolecule repairing agent is prepared from the following raw materials in parts by weight: 1-15 parts of gamma-hydroxybutyric acid, 1-20 parts of acetic acid, 1-30 parts of gamma-PGA, 1-8 parts of N-acetyl gluconic acid, 1-15 parts of Lunasin peptide, 10-50 parts of ST peptide, 1-20 parts of beta-hydroxy-alpha-aminobutyric acid, 1-40 parts of L-2-amino-3-hydracrylic acid, 20-60 parts of distilled water and 15-40 parts of sulfuric acid. According to the invention, in the charge-discharge cycle process of the lead-acid storage battery, the biomacromolecule repairing agent is adopted to continuously melt lead sulfate crystals and prevent the lead sulfate crystals from being attached to an electrode plate again, so that ecological restoration of the aged lead-acid storage battery is realized, and secondary pollution to the environment is avoided.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a biomacromolecule restoration agent for lead-acid batteries and a preparation method thereof. Background technique [0002] At present, with the rapid development of basic industries such as the automobile industry, 5G communications, electric power, transportation, railways, and computers, the market demand for batteries is increasing, which greatly promotes the rapid development of the battery industry. Among them, lead-acid batteries occupy a relatively high market share in the battery field due to their advantages of safety, stability, and high cost performance, and are widely used in automobile starting, communication fields, power batteries and energy storage batteries and other fields. [0003] The cycle life of a lead-acid battery has a lot to do with its operating environment, especially the depth of discharge during the cycle of the battery has a great impa...
