Problems solved by technology

[0004] In order to overcome the defects of low current conduction capacity, high internal resistance, uneven current distribution during charging and discharging, and poor performance in applications requiring high-rate charging and discharging of existing wound-type lead-acid batteries; the safety valve is explosion-proof The membrane is a single-membrane structure, which is easy to cause safety accidents and has disadvantages such as low strength and difficult processing of lead foil as a grid material of a wound structure battery. Valve winding battery, which can make the current distribution even during the charge and discharge process, effectively improve the current conduction capacity, improve the mechanical strength and anti-vibration performance of the electrode, reduce the internal resistance of the electrode, and have a high-rate charge and discharge of the super capacitor Features; safety valve double-membrane structure explosion-proof membrane makes the battery safer; the plate material is made of a mesh material woven from high-strength fiber material with good conductivity as the base material of the plate, which has good conductivity and the active material is not easy to detach. Compared with the original lead foil, the strength of the plate is greatly improved and the processing is easy

Abstract

Disclosed is a winding battery equipped with a continuous tab asymmetrical net-shaped electrode plate homodromous electrode capsule-film safety valve. The winding battery comprises a battery shell and a cell; the winding battery is characterized in that the cell comprises a positive electrode plate, a negative electrode plate and a diaphragm, and the cell is wound into a columnar body through a cell winding shaft; a positive electrode current collecting tray and a negative electrode current collecting tray are arranged on the end top parts of the two ends of the cell respectively; a tab, which is as long as the positive electrode plate, is arranged at the top end on one side, close to the positive electrode current collecting tray, of the positive electrode plate; a spiral groove body is formed in the current collecting tray; a negative electrode terminal is lead to a positive electrode end direction of the battery through an electrode terminal protection sleeve on the side surface of the battery shell; the negative electrode plate is a composite net-shaped electrode which takes a high-strength conductive fiber net as a bottom plate; and a metal oxide coating layer in strip-shaped distribution, such as ruthenium oxide and the like, and a negative active material, are arranged on the bottom plate. By virtue of the unique end plane current collecting structure and the composite net-shaped electrodes, the current conduction capability is effectively improved; meanwhile, the battery has the super-capacitor high-rate charging and discharging characteristic; and the dual-film safety valve is safer, so that the performance of the battery is better.

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 super 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...
