Problems solved by technology

Moreover, the plate is not easily polluted by impurities, which can reduce the self-discharge of the battery, and the battery quality can be better controlled. Therefore, at present, most battery manufacturers have begun to conduct preliminary research and application of internal formation, but the battery formation process is not yet available. Very mature, there are still many problems in the internalization of ordinary lead-acid batteries, such as long internalization time, low conversion rate of active substances, and difficulty in grouping, etc.

Abstract

The invention relates to an internal formation process of a super battery. The internal formation process comprises the following major steps: pouring a certain volume of acid solution with certain concentration into a super battery by use of a vacuum method first before formation, standing for 2-4 hours, and carrying out internal formation of the battery in a manner of four charge times and three discharge times with short time and multiple periods by adopting fixed current. Due to the multi-cycle charge-discharge manner, the porosity of a polar plate and the utilization rate of active substances are greatly increased, the influence on concentration polarization and electrochemical polarization is effectively alleviated, the capacitive character of a carbon material in the polar plate can be effectively activated, and therefore, the large current charge-discharge and cycle life properties of the super battery are improved.

Description

technical field [0001] The invention relates to a lead-acid storage formation process, in particular to an internal formation process of a super storage battery, and belongs to the technical field of storage batteries for power vehicles. Background technique [0002] Compared with tank formation, internal battery formation has many advantages. Its process simplifies the processes of plate washing, drying, battery supplementary power and tank formation, such as loading, welding, and sheet removal. Therefore, a lot of man-hours and energy can be saved, and there is no need to purchase chemical forming tank equipment and acid mist prevention equipment, and the battery cost can be reduced to a certain extent. Moreover, the plate is not easily polluted by impurities, which can reduce the self-discharge of the battery, and the battery quality can be better controlled. Therefore, at present, most battery manufacturers have begun to conduct preliminary research and application of in...
