Problems solved by technology

[0003] The design life of ordinary lead-acid batteries is generally 2-3 years, but its actual use is often only 1 year or less. The design life of maintenance-free lead-acid batteries is 7-15 years, but its actual service life is far short expected service life
Due to the wide application of lead-acid batteries, a large number of waste lead-acid batteries have been generated, resulting in a waste of resources

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to an energy storage lead-acid battery life extension liquid and a preparation method thereof. Background technique [0002] A lead-acid battery (VRLA) is a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. In the charged state of the lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the discharged state, the main component of the positive and negative electrodes is lead sulfate. The Frenchman Plante invented the lead-acid battery in 1859. It has experienced 150 years of development. In terms of theoretical research, lead-acid batteries have made great progress in terms of product types and varieties, and electrical performance of products. Whether it is in transportation , communication, electric power, military or ...
