Problems solved by technology

[0003] The external formation and charging process of conventional tubular lead-acid batteries is time-consuming and costly. With the increase of time during external formation, a large amount of acid mist will be brought out, which will cause pollution when discharged into the atmosphere. At the same time, the working environment of workers is poor, which affects the health healthy

Embodiment 1

[0020] A kind of internalization process of tubular lead-acid battery, comprising the following steps:

[0021] (1) Assemble the positive and negative raw plates into the battery case, pour 1.23~1.25g / cm 3 sulfuric acid solution, let it stand for 1 hour, so that the plate is fully soaked in the acid solution;

[0022] (2) The whole internalization process is divided into three stages. Different stages adopt different charge and discharge currents and times. The specific process is as follows:

[0023] The first stage: 0.5I 5 A charging 2 hours turn 0.8 I 5 A charge for 4 hours and then turn 1.1 I 5 A charge for 12 hours, then with 0.6 I 5 A discharge for 1 hour;

[0024] Phase II: 1.1 I 5 A charge for 16 hours, then with 1.0I 5 A discharge for 1.5 hours

[0025] 1.0 I 5 A charge for 15 hours, then with 1.0I 5 A is discharged to a monomer voltage of 10.2V;

[0026] The third stage: 0.8I 5 A charging 12 hours turn 0.6 I 5 A charge for 6 hours.

Embodiment 2

[0028] Phase 1: 0.4I 5 A charging 2.5 hours turn 0.7 I 5 A Charge for 3 hours and then switch to 1.0I 5 A charge for 11 hours, then with 0.4 I 5 A discharge for 1.5 hours;

[0029] Phase II: 1.0 I 5 A charge for 15 hours, then with 1.1I 5 A discharge for 1.5 hours

[0030] 1.1 I 5 A charge for 15 hours, then with 1.1I 5 A is discharged to a monomer voltage of 10.2V;

[0031] The third stage: 0.7I 5 A charging 11 hours turn 0.5 I 5 A charge for 6 hours.

[0032] All the other implementations are as in Example 1.

Embodiment 3

[0034] The first stage: 0.6I 5 A charging 2 hours turn 0.9 I 5 A charge for 3.5 hours and then turn 1.3 I 5 A charge for 10 hours, then with 0.7 I 5 A discharge for 1 hour;

[0035] The second stage: 1.3I 5 A charge for 15 hours, then with 1.2I 5 A discharge for 1 hour to 1.2I 5 A charging

[0036] 15 hours, then with 1.3I 5 A is discharged to a monomer voltage of 10.2V;

[0037] The third stage: 1.0I 5 A charging 10 hours turn 0.6 I 5 A charge for 6 hours.

[0038] All the other implementations are as in Example 1.

Abstract

The invention discloses an inner forming process of a tubular lead-acid storage battery, which comprises the following steps of: (1) assembling positive and negative raw polar plates into a battery shell, filling 1.23-1.25g / cm<3> of sulfuric acid solution and standing for an hour so that the polar plates are fully soaked in the acid liquor; and (2) dividing the whole inner forming process into three phases, wherein different charging and discharging currents and time are adopted in different phases. The inner forming process lasts for four days, thereby shortening the production period, omitting the cockamamie sections, such as discharge, water washing, drying, and the like after formation and saving the production cost. Meanwhile, the polar plates are formed in the battery shell in the production process, and therefore, the acid mist is less, the pollution is low, and the body damage to workers is less than that of outer formation.

Description

technical field [0001] The invention relates to a storage battery formation process, in particular to an internal formation process for tubular lead-acid storage batteries for electric tricycles, and belongs to the technical field of industrial storage batteries. technical background [0002] In the production of traditional tubular lead-acid batteries, the externalization process is generally used to convert raw plates into cooked plates. The raw plate is mainly composed of lead sulfate (including basic lead sulfate), lead oxide and free lead. Insert the positive plate (tube type) and negative plate alternately into an acid tank containing a certain concentration of dilute sulfuric acid. The permanent plates are welded together on one side. After standing for a period of time, use a DC power supply to charge at a constant current. The positive plate undergoes anodic oxidation reaction and gradually transforms into lead dioxide, and the negative pole undergoes cathodic redu...
