Abstract

The invention discloses a control method and device for winding a diaphragm. The method comprises: determining the length difference between the inner and outer ring diaphragms of a single core diaphragm when the power battery winding core is wound; Poor, control the coil length when the inner ring diaphragm and the outer ring diaphragm are incoming. The solution of the present invention can overcome the defects of the prior art such as large waste of leftover rolls, high manufacturing cost and low production efficiency, and realize the beneficial effects of small waste of leftover rolls, low manufacturing cost and high production efficiency.

Description

technical field [0001] The invention belongs to the technical field of batteries, in particular to a control method and device for a wound diaphragm, 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. 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 piece, which eventually leads to the ...
