Abstract

The invention relates to an asymmetric mixed pole plate same-direction electrode type porous current collection disc type winding type storage battery. The winding type storage battery comprises a battery shell and a battery cell. The winding type storage battery is characterized in that the battery cell is a cylindrical body formed by a positive plate, a negative plate and a diaphragm through the winding of a battery core reel, the diaphragm is located between the positive plate and the negative plate, and a positive current collection disc and a negative current collection disc are respectively arranged on the tops of two ends of the battery core; a lug, namely a positive continuous lug, having the same length with the positive plate is arranged on the top end of one side, close to the positive current collection disc, of the positive plate, and a spiral groove, namely a positive plate clamping groove, is formed in the positive current collection disc; a negative terminal is guided to the direction of a positive end of the battery through an electrode terminal protecting sleeve arranged on the side surface of the battery shell; and the negative plate is a mixed electrode, metal oxide coating layers are distributed on the mixed electrode in a point manner, and substances of the coating layers are ruthenium oxide and the like. The winding type storage battery has the beneficial effects that by utilizing a special end surface current collection structure and the mixed electrode, the current conduction capacity is effectively improved, and meanwhile, the battery has high-rate charging and discharging properties of a super-capacitor.

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; Charge and discharge use cases do not perform well.
