Abstract

A symmetric hybrid mesh plate co electrode double membrane safety valve coiled battery comprises a battery shell and a battery cell. The symmetric hybrid mesh plate co electrode double membrane safety valve coiled battery is characterized in that the battery cell comprises a positive plate, a negative plate and a diaphragm located between the positive plate and the negative plate, the positive plate, the negative plate and the diaphragm are coiled to form a column through a battery cell winding shaft, and a positive current collector and a negative current collector are arranged on the end roofs of the two ends of the battery cell; an electrode lug with the length equal to that of the positive plate is arranged at the top end of the side, close to the positive current collector, of the positive plate, the electrode lug is a positive continuous electrode lug, and a spiral slot, namely, a positive plate clamping slot is formed in the positive current collector; the positive plate and the negative plate are hybrid mesh electrodes which are provided with metal oxide coatings such as ruthenium oxide distributed in a dotted mode. The symmetric hybrid mesh plate co electrode double membrane safety valve coiled battery has the advantages that the battery has the high current conducting capacity, super-capacitor high-rate charging and discharging capacities and the characteristic that a double membrane safety valve makes the battery safer.

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...

[0003] 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 the lead foil used as the grid material of the winding structure battery has disadvantages such as low strength and difficult processing. 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 high-rate charging and discharging characteristics of super capacitors; safety The double-membrane structure explosion-proof film of the valve makes the battery safer; the plate material is made of mesh material woven with 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 is greatly improved and it is easy to process
