A winding battery with asymmetric hybrid meshed pole plates, same-direction electrodes and dual-membrane safety valve 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 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 is formed in the current collection disc, a negative terminal is led to a positive terminal direction of the battery by an electrode terminal protection sleeve, the electrode terminal protection sleeve is arranged on a side surface of the battery shell, the negative pole plate is the hybrid meshed electrode, a high-strength conductive fiber mesh is used as a bottom plate, and metal oxide coating layers such as ruthenium oxide, which are arranged in a dot way, and a negative active substance are arranged on the bottom plate. The winding has the advantages that by a special end-surface current collection structure and the hybrid meshed electrodes, the current conduction capability is effectively improved; and meanwhile, the battery has characteristic of a supercapacitor, the dual-membrane safety valve is safer, and 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...
