Container formation method for low-liquid type lead-acid battery

Abstract

The invention relates to a battery formation process, and particularly relates to a container formation method for a low-liquid type lead-acid battery, which comprises the following steps: acidifying a battery, cooling the acidified battery in a water bath, connecting the battery with a wire, and respectively performing first-stage charge, first-stage discharge, second-stage charge and second-stage discharge on the battery; and especially after the sixth constant-voltage charge, performing acid extraction on the battery, and then discharging. Free acid liquid has been extracted before discharge, so that the battery is charged with a current of 1.5A, thus avoiding heating and dehydration phenomenon of the battery. According to the invention, the production cycle is shortened, the labor intensity of working personnel is reduced, the production efficiency is increased, the electric energy consumption is reduced, the production cost is reduced, and the production benefits are increased.

Description

Technical field [0001] The invention relates to a battery formation process, in particular to a lean-liquid lead-acid battery internal formation process. Background technique [0002] Generally, there are two main formation methods for lean-liquid lead-acid batteries: one is external formation of the battery, where the electrode plates are formed into a battery and then recharged; the other is internal formation of the battery, where the raw plates are directly assembled into a finished battery. Then it is being transformed. [0003] The advantages of battery internal formation over external formation are: cost savings, reduced production intermediate links, reduced environmental pollution, plates are not easily polluted by impurities and other substances, battery self-discharge is small, float charge voltage is uniform, and battery performance changes little. [0004] In the current traditional 12V12Ah lead-acid battery formation process for electric bicycles, see Table 1: [0005] ...

AI Technical Summary

Problems solved by technology

[0009] In order to solve the problems that the formation time of the lean liquid lead-acid storage battery is too long and the power consumption in the formation is too long, resulting in low production efficiency and high production cost, the present invention provides a battery that saves formation time, consumes less power, and effectively improves production efficiency. Internal formation process of lean liquid lead-acid battery to save production start and battery performance
