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...

[0004] In order to overcome the defects of low current conduction capacity, high internal resistance, uneven current distribution during charging and discharging of the existing wound lead-acid batteries, and poor performance in applications requiring high-rate charging and discharging; safety The valve explosion-proof membrane is a single-membrane structure that is easy to cause safety accidents, and the lead foil used as the grid material of the winding structure battery has low strength and difficult processing. Valve winding battery, which can make the current distribution even during the charging and discharging 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 and improves the safety of the battery; the plate material uses a mesh-like material woven from a high-strength fiber material with good conductivity as the base material of the plate. Well, the active material is not easy to detach, the strength of the plate is greatly improved compared with the original lead foil, and the processing is easy
