Title:
PRESS ROLLER DEVICE AND LITHIUM SUPPLEMENTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/029641
Kind Code:
A1
Abstract:
The present application provides a press roller device and a lithium supplementing apparatus. The press roller device comprises a first press roller and a second press roller. The second press roller is used for working in conjunction with the first press roller to roll a lithium strip. The first press roller comprises a first rolling surface used for rolling the lithium strip, and the first rolling surface is concave in a direction close to the axis of the first press roller, so that the first rolling surface can compensate for the amount of expansion of the first press roller when the first press roller rolls and presses the lithium strip. The first press roller is provided with the first rolling surface concave in the direction close to the axis of the first press roller, equivalently, a concave portion is provided on the surface of the first press roller, and the size of the concave portion can compensate for the thermal expansion size of the first press roller and the second press roller, so that even after the first press roller and the second press roller expand, the rolling gaps of the first press roller and the second press roller tend to be consistent, so that the extension uniformity of the lithium strip can be improved, and the risk that the conveying of the lithium strip is influenced due to excessive accumulation amount of the lithium strip between the first press roller and the second press roller is reduced.
