Multi-stage circulatory forming and activating process for lead-acid storage battery for storing energy

Abstract

The invention discloses a multi-stage circulatory forming and activating process for a lead-acid storage battery for storing energy. A five-charging and four-discharging principle is adopted, shallow discharging is carried out twice, high current discharging is carried out once, full capacity discharging is carried out once, in a charging process, average single voltage is within 2.6 V, charging is implemented by 1-2 steps in each of five charging stages, and before forming is finished, low-constant-current charging is implemented once to remove free acid. By the multi-stage circulatory forming and activating process for the lead-acid storage battery for storing energy, charging acceptance of a pole plate is improved, consistency of batteries is good, capacity attenuation rate is low, cycle life is prolonged, and use requirements of the lead-acid storage battery for storing energy are met. The multi-stage circulatory forming and activating process for the lead-acid storage battery for storing energy is short in forming period and high in efficiency.

Description

Technical field [0001] The invention relates to a process for internalization and activation of lead-acid batteries for energy storage, and belongs to the field of manufacturing industrial lead-acid batteries. Background technique [0002] At present, most lead-acid batteries used for energy storage are formed by external formation of the electrode plate and then assembled or internal formation process of three-charge and two-discharge system. The external formation process of the electrode plate is relatively simple to operate and can eliminate unqualified plates, but environmental pollution during the production process Larger, the waste of resources is serious, and after the battery is assembled, the battery still needs to be supplemented, and the production cost is higher. Three-charge and two-discharge system internal formation, the process is relatively simple, the pollution is small, but the formation charging cycle is relatively long, the charging capacity is large, the p...

Problems solved by technology

[0002] At present, most lead-acid batteries for energy storage are formed by external formation of plates and then assembled or internal formation process of three-charge and two-discharge system. The external formation process of plates is relatively simple to operate, and unqualified plates can be eliminated, but the production process pollutes the environment Larger, serious waste of resources, and after the battery is assembled, the battery still needs to be supplemented with electricity, and the production cost is high

Three-charge and two-discharge internal formation, the process is relatively simple, and the pollution is small, but the formation charging cycle is relatively long, the charging capacity is large, and the production efficiency is low. After formation, unqualified plates cannot be removed, and the battery consistency is relatively poor.
