Continuous lug spirally wound lead-acid storage battery

Abstract

The invention relates to a continuous lug spirally wound lead-acid storage battery. The continuous lug spirally wound lead-acid storage battery comprises a battery case and a battery core and is characterized in that the battery core is wound into a cylindrical body by a positive plate, a negative plate and a diaphragm arranged between the positive plate and the negative plate by virtue of a battery core scroll, and a positive flow collecting disk and a negative flow collecting disk are respectively arranged at the tops of the two ends of the battery core; the positive plate is provided with one lug, namely a positive continuous lug, with the length equal to that of the positive plate at the top end of one side close to the positive flow collecting disk; and a spiral slot body, namely a positive plate clamping slot, is formed in the flow collecting disk, and the continuous lug of a pole piece is clamped into the clamping slot along the pole piece clamping slot and is fixed by adopting a welding method. The continuous lug spirally wound lead-acid storage battery provided by the invention has the beneficial effects that due to a unique end face flow collecting structure, flow collecting area of a battery pole piece is increased, and mechanical strength and anti-shake performance of an electrode are greatly improved, so that safety of the battery is improved, and cycle life of the battery is prolonged; and the continuous lug spirally wound lead-acid storage battery has a broad application prospect in the storage battery manufacturing field.

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 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 cause...
