Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery anode material processing, and in particular to a lithium battery anode material oxidation processing device and a processing process thereof. Background Art

[0002] Lithium battery anode material refers to the material used as the negative electrode in lithium batteries. Its main function is to store lithium ions during the charging process and release lithium ions during the discharge process. The performance of lithium battery anode material directly affects key indicators such as the energy density, power density, cycle life and safety of lithium batteries.

[0003] When lithium battery anode plates are produced, they need to be subjected to oxidation electroplating treatment. Anodizing is a metal surface treatment process that uses electricity in an electrolyte solution to make the metal product act as an anode to form a dense oxide film. This oxide film can significantly improve the metal's corrosion resistance, hardness, wear resistance, insulation and heat resistance.

[0004] During oxidation plating of lithium battery anode plates, a plurality of lithium battery anode plates are usually stored inside a supporting frame, and then the supporting frame drives the plurality of lithium battery anode plates into an electrolytic cell for oxidation plating. However, the supporting frame and the plurality of lithium battery anode plates are statically stored in the electrolytic cell for processing, which not only requires subsequent processing of the lithium battery anode plates after the oxidation plating of a batch of lithium battery anode plates is completed, but also the oxidation plating efficiency of the lithium battery anode plates statically stored in the electrolytic cell is low, thereby reducing the production efficiency of the oxidation plating of the lithium battery anode plates.
