Continuous tab equidirectional electrode coiled lead acid battery

Abstract

A continuous tab equidirectional electrode coiled lead acid battery comprises a battery shell and an electrical core. The battery is characterized in that the electrical core is a cylindrical object formed by coiling a positive plate, a negative plate and a diaphragm positioned between the positive plate and the negative plate through an electrical core reel; two top ends of the electrical core are respectively provided with a positive current collector plate and a negative current collector plate; the positive plate, close to the top of one side of the positive current collector plate, is provided with a tab, namely a positive continuous tab, which has the same length as the positive plate; the positive current collector plate is a plate-shaped body, which is provided with a spiral groove, namely a positive plate groove, which spirally fits with the positive plate; a positive continuous tab of the positive plate is clamped in the positive plate groove; and a negative terminal leads to the direction of the positive electrode side of the battery through an electrode terminal protective sleeve arranged at the side surface of the battery shell. The invention has the following beneficial effect: through the unique current collector structures at the end faces, current collector area of the battery plates is increased and mechanical strength and anti-vibration performance and security of the electrode are greatly enhanced.

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...
