Abstract

The invention discloses a control method and device for winding a diaphragm and a battery. The method comprises the following steps: determining the length difference of inner and outer ring diaphragmof a single core diaphragm during winding of a power battery core; According to the determined length difference of inner and outer ring diaphragms of single core diaphragm, the coil length of innerring diaphragm and outer ring diaphragm is controlled. The scheme of the invention can overcome the defects of large waste amount of scrap volume, high manufacturing cost and low production efficiencyin the prior art, and realize the beneficial effects of small waste amount of scrap volume, low manufacturing cost and high production efficiency.

Description

technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to a control method, device and battery of a wound diaphragm, and in particular to a method for improving the utilization rate of a wound diaphragm, a device corresponding to the method, and a battery wound based on the device. Battery. Background technique [0002] The station or station that combines the positive electrode, negative electrode, and separator paper of the battery by hand or machine is called a winding station. A battery composed of batteries formed in a winding manner is called a wound battery; a wound battery is also called a battery cell, and people in the battery industry call it a wound core. [0003] When winding the existing power battery core, the upper and lower separators are wound with the same length. When winding, there is a difference in length between the inner and outer separators of the single layer due to the thickness of the pole pie...
