Description

Technical Field

[0001] The utility model relates to the technical field of sodium-ion battery processing, in particular to a grinding machine for sodium-ion battery electrode sheets. Background Technique

[0002] A sodium-ion battery is a secondary battery that mainly relies on the movement of sodium ions between the positive electrode and the negative electrode to work, similar to the working principle of a lithium-ion battery. An electrode sheet refers to the sheet material that constitutes the positive and negative electrodes of the battery. The electrode sheet plays an important role in energy conversion and transmission in the battery. Usually, a battery consists of a positive electrode, a negative electrode, and an electrolyte. The electrode sheets are divided into two types: positive electrode sheets and negative electrode sheets.

[0003] In the prior art, a Chinese patent with the publication number CN205310004U discloses a battery electrode sheet grinding device that polishes the nickel foam on the surface of the battery electrode sheet through a rotating roller, thereby improving the efficiency, reducing the labor intensity, and having a simple structure and convenient use;

[0004] However, when this device is used, it can only remove the nickel foam on one side of the battery electrode sheet at a time. When removing the nickel foam on other sides of the battery electrode sheet, it is necessary to manually change the direction of the battery electrode sheet and re-fix the battery electrode sheet, resulting in a slow cleaning speed of the outer surface of the battery electrode sheet and a low grinding efficiency of the battery electrode sheet. Therefore, it does not meet the existing requirements, and for this reason, we propose a grinding machine for sodium-ion battery electrode sheets. Content of the Utility Model
