Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery anode material cleaning, in particular to a separable lithium battery anode material cleaning device. Background Technique

[0002] Lithium-ion batteries generally use lithium metal oxides as the cathode material and graphite as the anode material. An electrolyte is added to the cathode material or anode material and separated by a separator to form a chemical power supply system. Lithium battery anode materials are generally made of easily graphitizable carbon materials as raw materials, and artificial graphite anodes are prepared through processes such as grinding, classification, granulation, and graphitization. The energy density of lithium-ion batteries depends to a large extent on the anode material. Since the commercialization of lithium-ion batteries, the most mature and widely used anode material is carbon material, and the most important one is still graphite. Before graphite itself is produced, it needs to be cleaned to ensure the quality of production.

[0003] After the existing lithium battery anode material cleaning device finishes cleaning, it is necessary to fish out the graphite material inside the device and then drain the water inside the device, which is time-consuming and laborious and reduces work efficiency. Moreover, when cleaning the graphite material, cleaning agents need to be added to make the cleaning of the graphite material more thorough. During the process of adding the agents, the amount of the added agents cannot be quantitatively controlled and needs to be continuously added manually. In view of this technical problem, this application proposes a separable lithium battery anode material cleaning device. Content of the Utility Model
