[0002] The negative electrode material may be exposed to various impurities, oils or other contaminants during production or processing. These contaminants may come from production equipment, environment or processing. If these impurities are not removed, they may affect the electrochemical properties of the negative electrode material and thus the overall performance of the lithium battery. For example, impurities may cause internal short circuits in the battery, capacity decay or shortened cycle life.

[0003] When cleaning existing negative electrode materials, most of them are directly put into a cleaning tank after crushing, and then organic solvents and water-based cleaning agents are introduced into the tank, and the negative electrode materials are cleaned with flowing cleaning agents. However, in actual use, since the negative electrode materials are stacked in the cleaning tank, the negative electrode materials located in the center cannot be effectively cleaned, and the cleaning effect is poor. In addition, such cleaning wastes cleaning agents, and there are certain shortcomings in its use. For this reason, we propose a lithium-ion battery negative electrode raw material washing device.
