Wound storage battery with symmetric composite electrodes and perforated collector plates

Abstract

The invention provides a wound storage battery with symmetric composite electrodes and perforated collector plates. The wound storage battery comprises a battery case and a battery core; the wound storage battery is characterized in that the battery core is a cylindrical body formed by winding a positive plate, a negative plate and a membrane located between the positive plate and the negative plate through a battery core reel; a positive collector plate and a negative collector plate are arranged at the tops of two ends of the battery core separately; a tab, namely a positive continuous tab, which is equal to the positive plate in length is arranged at the top end of one side, close to the positive collector plate, of the positive plate; a spiral groove body, namely a positive plate clamping groove is arranged in the corresponding collector plate; the positive plate and the negative plate are composite electrodes and are constructed by arranging a metal oxide coating distributed in a strip on a lead plate as a bottom plate; and metal oxide coating materials such as ruthenium oxide and the like distributed in a strip are arranged on the lead plate. The wound storage battery has the beneficial effects that the current conducting capability is effectively improved through unique end-surface collector structures and composite electrodes, and meanwhile, the battery has high-rate charging and discharging characteristics 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. Contents of the invention [0003] In order to overcome the defects of low current conduction capacity, high internal resistance, uneven current distribution during charging...
