Lead-acid storage battery electrode group of which positive electrodes and negative electrodes have equal service life

Abstract

The invention belongs to the technical field of production of storage batteries, and particularly relates to a lead-acid storage battery electrode group of which positive electrodes and negative electrodes have equal service life. The lead-acid storage battery electrode group comprises multiple electrode plate groups which are in series connection, each electrode plate group is formed by positiveelectrode plates and negative electrode plates which are in parallel connection, AGM clapboards are arranged between every two adjacent electrode plate groups, and the negative electrode plates are connected with electrode plate link busbars. By means of the lead-acid storage battery electrode group, according to different reaction mechanisms of the positive electrode plates and negative electrodeplates in the charging and discharging process of a storage battery, by adjusting structures of current collecting ribs of plate grids of the positive electrodes and negative electrodes, current is reasonably distributed at all the positive electrode plates and the negative electrode plates as required in the charging and discharging process of the storage battery to guaranteed that active substances, close to current collectors and away from the current collectors, on the positive electrode plates and the negative electrode plates release energy simultaneously, and the purpose that the positive electrode plates and the negative electrode plates have the equal service life is achieved.

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...
