Embodiment Construction

[0045] Below in conjunction with specific embodiment further illustrate the present invention.

[0046] The battery 12V12Ah that adopts, the method for the internal formation of the accumulator of the comparative example adopts three charging, two discharges and five stages of technology, and the internal formation method of the accumulator of the embodiment adopts the technical scheme of the present invention.

[0047] After adding acid to the battery, immediately place the battery in cooling water to cool down, and let the battery stand for 2 + Let the sulfuric acid permeate the plates and separators for 0.5 hours, drop the temperature of the battery to 30°C~40°C, and then turn on the electricity for formation. During the formation process, control the water temperature so that the formation temperature is not higher than 50°C. The specific process conditions are shown in Table 1 to Table 5. (Note: "-" in the table means discharge).

Abstract

The invention discloses a method for internal chemical reaction in a battery via charging five times and discharging four times, belonging to the technical field of a battery. The battery is of a 12V12Ah type. The method adopts nine stages with charging five times and discharging four times, and comprises the following steps: immediately placing the battery in cooling water for cooling after acid is added, keeping the battery static for 2 plus 0.5 hours so that pole plates and separators are completely impregnated in sulfuric acid, powering for chemical reaction when the temperature of the battery is reduced to 30-40 DEG C, controlling the water temperature during the chemical reaction so that the temperature of the chemical reaction is no higher than 50 DEG C, starting the internal chemical reaction of the battery, charging a plurality of times with alternating current during the internal chemical reaction, and keeping the battery static for a certain period each time after charging. When the internal chemical reaction in the method is adopted for the battery, the initial capacity of the battery can be increased by 4.1-9.1 percent, the rate of utilization of active substances of the battery can also be increased, and the difference of PbO2 contents inside and outside the finished pole plates can be reduced from 17.1 percent to 5.6-7.6 percent after charging.

Description

technical field [0001] The invention relates to a storage battery formation process, in particular to a five-charge and four-discharge storage battery internal formation method, which belongs to the technical field of storage batteries. Background technique [0002] Lead-acid batteries have long service life, large capacity, good high-current discharge, high charge acceptance, excellent battery uniformity, small self-discharge, high reaction efficiency, and low raw materials, and have been used until now. While researching and developing new varieties, various manufacturers are constantly exploring ways to improve production efficiency. In the past, in order to shorten the formation time, various explorations have been made, such as increasing the temperature of the formation electrolyte, increasing the formation current or increasing the density of the electrolyte, etc., but the formation temperature is too high, resulting in insufficient initial capacity of the battery; in...
