Abstract

Disclosed is a winding type storage battery equipped with a continuous tab symmetrical mixed electrode capsule-film safety valve. The winding type storage battery comprises a battery shell and a cell; the winding type storage battery is characterized in that cell comprises a positive electrode plate, a negative electrode plate and a diaphragm positioned between the positive electrode plate and the negative electrode plate, 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, and namely, a positive electrode continuous tab, 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, namely a positive electrode plate clamping groove, is formed in the current collecting tray; the positive electrode plate and the negative electrode plate are mixed electrodes, and are configured to take lead plates as bottom plates; and metal oxide coating layers in dotted distribution are arranged on the lead plates. The winding type storage battery has the beneficial effects as follows: by virtue of the unique end plane current collecting structure and the mixed electrodes, the current conduction capability is effectively improved; meanwhile, the battery has the super-capacitor high-rate charging and discharging characteristic; and by virtue of the dual-film safety valve, the battery can be better protected and the character of service of the battery is 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 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...
