Embodiment Construction

[0006] When carrying out the internal formation of lead-acid batteries, first fill the lead-acid batteries with electrolyte, and then let them stand for 2 to 3 hours to perform formation charge and discharge. The composition is divided into five stages: in the first stage, charge with a current of 5 times the battery capacity, represented by 5CA, and after the voltage reaches 2.45V / cell, discharge with 1CA for 10 seconds; in the second stage, charge with a current of 2.5 times the battery capacity Current charging, when the charging voltage reaches 2.60V / cell, use 1CA to discharge for 10 seconds; in the third stage, charge with a current of 1.0 times the battery capacity, when the charging voltage reaches 2.80V / cell, use 1CA to discharge for 10 seconds In the fourth stage, charge with a current of 0.5 times the battery capacity, and when the charging voltage reaches 2.80V / cell, discharge it with 1CA for 10 seconds; in the fifth stage, charge with a current of 0.15 times the bat...

Abstract

A rapid forming process used for internal formation of lead-acid storage batteries relates to a lead-acid storage battery. At present, the forming processes for lead-acid storage batteries include the following methods: 1, external forming method which causes greater pollution and is more energy consumption; and 2, conventional internal forming method which takes too long time for formation and is low in production efficiency. The rapid forming process for internal formation of lead-acid storage batteries is characterized in that a lead-acid storage battery is filled with an electrolytic solution, stands for 2-3 hours, and then is subjected to charge/discharge formation; the whole process allows the current deviation within plus or minus 15% as well as the voltage deviation within plus or minus 1.0%; the internal temperature of the lead-acid storage battery is controlled in range from 25 to 65 DEG C; and during the charge process, the first four stages take charge voltage as the conversion condition, and the fifth stage takes charge duration as the conversion condition. The invention has the benefit that the rapid forming process used for internal formation of lead-acid storage batteries has the advantages of relatively short formation duration, high production efficiency, cleanness, environmental protection and low energy consumption.

Description

technical field [0001] The invention relates to a lead-acid storage battery, in particular to a rapid formation process for internal formation of a lead-acid storage battery. Background technique [0002] At present, in the lead-acid battery industry, the formation process methods of lead-acid batteries include: 1. The external formation method (also called plate formation) is adopted, which is to place the lead-acid battery assembly plate in the formation tank with electrolyte Then charge and discharge the lead-acid battery plate in the deionized environment, and then go through anti-oxidation, drying and other process processes, and then put the plate into the lead-acid battery shell when the lead-acid battery is assembled body to go. However, this process method pollutes a lot and consumes a lot of energy; 2. The conventional internal formation method (also called battery formation) is adopted, which is to directly pack the inactive lead-acid battery plates into the batt...
