Abstract

A winding type storage battery with asymmetric hybrid pole plates, same-direction electrodes and a 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, namely a positive continuous 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, namely a positive pole plate clamping 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 electrode, metal oxide coating layers which are arranged in a dot way are arranged on the hybrid electrode, and the substances of the coating layers are ruthenium oxide and the like. The winding type storage battery has the beneficial effects that the battery has relatively high current conduction capability and high-rate charge and discharge capability of a supercapacitor, and the battery is safer due to the dual-membrane safety valve.

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] 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 serious heating and the battery temperature is too high, which will cause safety hazards; The performance of charging and discharging is not good; the explosion-proof membrane of the general battery safety valve is a single-membrane structure. Once the membrane is corroded by acid, the safety valve will lose its prot...
