Winding battery with continuous tabs, meshed pole plates, membrane safety valve and porous current collection discs

Abstract

A winding battery with continuous tabs, meshed pole plates, a membrane safety valve and porous current collection discs comprises a battery shell and a battery cell and is characterized in that the battery cell forms a cylindrical body by winding a positive pole plate, a negative pole plate and a separator by a battery cell winding shaft, wherein the separator is arranged between the positive pole plate and the negative pole plate, a positive current collection disc and a negative current collection disc are respectively arranged at tops of two ends of the battery cell, a tab, namely a positive continuous tab is arranged at a top end of one side, near to the positive current collection disc, of the positive pole plate and is equal to the positive pole plate in length, a spiral groove, namely a positive pole plate clamping groove is formed in the current collection disc, and the continuous tabs of the pole plates are clamped in the pole plate clamping grooves along the pole plate clamping grooves and are fixed by a welding method. The winding battery has the beneficial effects that by a special end-surface current collection structure, the current collection areas of the battery pole plates are expanded, and the mechanical strength and the anti-vibration performance of electrodes are substantially improved; the battery can be protected very well by the dual-membrane safety valve; and the high-strength fiber meshed pole plates are high in strength and good in conductivity, so that the performance of the battery is further improved.

Description

technical field [0001] The invention relates to a lead-acid storage battery, in particular to a high-power, high-rate discharge wound lead-acid storage battery, which belongs to the technical field of storage battery processing and manufacturing. Background technique [0002] Traditional lead-acid battery manufacturing processes and technologies have gone through more than a century. In the course of more than a century of development, traditional production and processing technologies have been continuously innovated, and new technologies and equipment have been continuously adopted. [0003] At present, most of the traditional winding lead-acid batteries use single or multiple tabs as the current collection method. During the discharge process, the current distribution is uneven, and it is difficult to realize high-current charge and discharge. In addition, when charging and discharging with high current, due to the large internal resistance of the battery, it will cause...
