Problems solved by technology

In the current internalization process, it is generally believed that low-current charging is more energy-saving, so the charging current in the main charging stage will not exceed 0.1C / A, but this will cause the internalization time to be too long, and the battery online time needs 140 Many hours or even longer, causing the manufacturer's equipment and space to be tense, and affecting product delivery

Embodiment Construction

[0004] The present invention adopts internal formation, that is, directly assembling raw plates and filling acid in the battery, and then performing formation, which includes several times of alternating charging and discharging in the main charging stage, the charging current is 0.13-0.27C / A, and the total charging time 35 to 55 hours, the discharge current is 0.13 to 0.27C / A, the discharge time is 0.5 to 8 hours, after the end of the main charging stage, it is still for 0 to 3 hours, and the capacity judgment discharge is performed after the static state, and after the capacity judgment discharge Carry out the second stage of charging, the charging current is 0.02C-0.1C / A, and the total charging time is 18-21 hours, where C represents the rated capacity of the battery. C is generally the rated capacity of the 10-hour rate or 20-hour rate of the battery. The static referred to in the present invention means that the pole plate is placed in the acid solution without charging o...

Abstract

This invention provides an internal formation method for pole plates of lead acid batteries including a first stage of several times of alternate charge and discharge, in which, the charge current is 0.13-0.27C / A, the total charge time is 35-55 hours, the discharge current is 0.13-0.27C / A, the discharge time is 0.5-4.5 hours, the battery is put at rest for 0-3 hours after the first stage then to be discharged according to the capacitance then the second stage of charge is done and the charge current is 0.02C-0.1C / A, the total time is 18-21 hours, in which, C expresses the rating volume of the battery.

Description

technical field [0001] The invention relates to a chemical formation method of lead-acid accumulator polar plates. Background technique [0002] The plates of the early lead-acid batteries adopt the external formation process, that is, the plates are placed in the formation tank for formation. This kind of production process is various, and energy consumption is big, and environmental pollution is also more serious. In recent years, in order to overcome this shortcoming, most domestic manufacturers have adopted the internal formation process of the battery through process research and production practice, that is, directly assembling the raw plate in the battery, filling the battery with acid, and then performing the formation. In the current internalization process, it is generally believed that low-current charging is more energy-saving, so the charging current in the main charging stage will not exceed 0.1C / A, but this will cause the internaliz...
