Embodiment 1

[0044]In this embodiment, the number of negative pole vertical ribs 7 is five, and the number of negative pole horizontal ribs 6 is sixteen. The distance between the negative pole vertical ribs 7 and the adjacent negative pole second vertical ribs is 9.5mm and 11mm respectively. . The distances between consecutive adjacent negative electrode transverse ribs 6 are: 6.46mm, 6.66mm, 6.86mm, 7.06mm, 7.26mm, 7.46mm, 7.66mm, 7.86mm, 8.06mm, 8.26mm, 8.36mm, 8.46mm , 8.56mm, 8.66mm, 8.76mm, 8.86mm. The width of the upper part of the negative electrode vertical rib 7 is 1.0 mm, and the width radiating downwards to the bottom is 1.4 mm, with an even transition in the middle. After discharging, the negative electrode grid provided by this embodiment was tested for PbSO4 content in different positions. The discharged product was uniform and met the set requirements. The cycle life curve of the battery produced by using this negative electrode grid is shown in the table below.

Abstract

The invention belongs to the technical field of storage battery production, and in particular relates to life-span pole groups such as positive and negative plates of lead-acid storage batteries. A lead-acid storage battery with positive and negative plates and other life-span pole groups, including a plurality of series-connected pole plate groups, each pole plate group is connected in parallel by positive pole plates and negative pole plates, and the adjacent pole plate groups are provided with There is an AGM separator, and the negative electrode plate is connected to the electrode plate connection bus bar. According to the different reaction mechanisms of the positive and negative plates in the charging and discharging process of the battery, the electrode group provided by the invention can promote the current flow of the battery to follow the requirements in the process of charging and discharging by adjusting the structure of the current-collecting ribs of the positive and negative grid sheets. Reasonable distribution on the positive and negative plates, so as to ensure that the active materials on the positive and negative plates close to the current collector and away from the current collector release energy at the same time, so as to achieve the purpose of the life of the positive and negative plates.

Description

technical field [0001] The invention belongs to the technical field of storage battery production, and in particular relates to life-span pole groups such as positive and negative plates of lead-acid storage batteries. Background technique [0002] It has been 150 years since the battery was created, and the application fields of the battery are very extensive. Due to the limitation of the production method of the battery, after the service life of the battery is over, the active materials on the upper and lower parts of the positive and negative plates cannot be terminated at the same time, resulting in a waste of resources and at the same time, due to the difference in utilization rate, the partial premature failure of the product reduces the product life. In recent years, many scholars and experts have devoted themselves to studying the ratio of active materials between positive and negative electrodes in order to achieve the most scientific ratio. However, in the actual...
