Embodiment 1

[0074]

[0075]

[0076] The solution of the previous application for "a treatment equipment and method for reducing warpage of electrolytic copper foil" has the disadvantage that once the voltage is not properly selected, damage is caused and the entire roll of copper foil will fail. Therefore, in the actual application of the scheme, the voltage value selection needs to be cautious.

[0077] For this issue, the project research and development team broke the technical prejudice brought by the previous application and proposed the idea of ​​energizing on both sides.

[0078] The source of this idea is: even if there is damage, the damage will occur on both sides of the width direction of the rolled copper foil; after the power is turned on, it is only necessary to rewind and trim the edges first.

Abstract

The invention discloses end part type electric heating electrolytic copper foil anti-warping equipment and a working method thereof, and belongs to the technical field of new energy automobile power battery electrolytic copper foils. According to the technical key points, the first end cover comprises an end cover plate, and a through hole is formed in the middle of the end cover plate; the end cover plate comprises an end cover plate body and a plurality of ring-like electrodes arranged on the end cover plate body; each ring-like electrode comprises x electrodes, and the x electrodes are distributed in a ring shape; the center of the annular array of the plurality of ring-like electrodes and the circle center of the through hole are the same point; the size of the through hole is matched with that of the wind-up roller; the second end cover and the first end cover are the same in structure. By adopting the end part type electric heating electrolytic copper foil anti-warping equipment and the working method thereof, the damage to the rolled copper foil can be further avoided.

Description

technical field [0001] The invention relates to the field of electrolytic copper foils for power batteries of new energy vehicles, and more particularly, to an end-type electric heating electrolytic copper foil anti-warping device and a working method thereof. Background technique [0002] Warpage index has always been a key index of lithium battery copper foil. [0003] The warpage treatment method of lithium battery copper foil is summarized in document 1: CN111485260B (Guangdong Jiayuan Technology Co., Ltd., low warpage electrolytic copper foil for secondary battery, manufacturing method): heat treatment method, additive method, rolling method, surface treatment method. [0004] Document 2: CN113151759B (Guangdong Jiayuan Technology Co., Ltd., an electric heat treatment device for reducing the warpage of copper foil) innovatively proposed: electric heating method. [0005] The applicant's previous application "An Electrolytic Copper Foil Warp Reduction Treatment Device ...
