Problems solved by technology

As the country continues to strengthen the implementation of safety and environmental protection regulations, as a dangerous product, the transportation cost of liquid-filled lead-acid batteries will continue to increase, and liquid-filled transportation will be very difficult; while dry-charging the plates, The tank formation method is required, special treatment and drying are required after the plate is discharged, the acid mist pollution is relatively large, the energy consumption is relatively large, and the investment in equipment is relatively large, so it cannot be applied on a large scale

Abstract

The invention relates to a processing method of a tubular lead-acid battery, which belongs to the field of batteries. The processing method is characterized by comprising the following steps: performing battery formation treatment on the battery under a low-density electrolyte environment; performing heavy-current discharge treatment during the later stage of battery formation; performing acidity control treatment on the battery; and using a sealing plug to seal a liquid injection port of the battery. Low-density electrolyte is adopted for formation during the battery formation, so that the formation efficiency and the charging level of a whole polar group can be improved; the heavy-current discharge is adopted during the later stage of the formation, so that a dense protection layer can be formed on the surface of the polar group, the polar group can be protected, and the reaction speed of consumption of active substances during the storage period can be deferred; and the acid content in the polar group is controlled within a appropriate range, the storage is convenient, the sealing plug is adopted for sealing, the expansion extent of the battery is controlled, the oxidation of the polar group of the battery can be prevented, the charge retention capability is improved, a user affuses the electrolyte before use, the simple supplementary charging is performed, the safety in transportation of the battery is improved, and the using cost of the user is also reduced.

Description

technical field [0001] The invention relates to a processing method for a tubular lead-acid storage battery, which belongs to the technical field of storage batteries. Background technique [0002] At present, tubular lead-acid batteries as DC power supplies are mainly used in forklifts, trucks, underground mining locomotives and other equipment, and are widely used in airports, stations, ports, docks, industrial and mining enterprises and other fields. At present, the tubular lead-acid batteries in my country are mainly flooded batteries, which need to be charged for a long time (more than 72 hours) before use. The initial charge requires special charging and cooling equipment, and requires high professional skills. Finish. In order to solve this problem, there are currently two main ways: the manufacturer conducts initial charging, and then transports it to the user with liquid; the manufacturer performs dry charging on the plate, and then the user performs supplementary c...
