[0002] The recycling of positive and negative electrode materials of batteries is mainly the process of separating and reusing the positive and negative electrode materials in waste batteries. In the recycling process, inert gases are usually used to protect and treat certain easily oxidized materials to prevent oxidation reactions from occurring. In the recycling process of positive and negative electrode materials of batteries, when the materials need to be subjected to high temperature treatment or other treatments, inert gases such as nitrogen or argon are usually used for protection. Inert gases can wrap the materials during the treatment process to form an inert atmosphere, prevent oxygen from contacting easily oxidized materials, and ensure stable treatment of the materials. Therefore, in the recycling process of positive and negative electrode materials of batteries, when it comes to the link where the materials need to be protected from oxidation, inert gases need to be used to protect the materials to ensure the smooth progress of the recycling process and to ensure the quality and effect of the recycled materials; how to realize the adaptive control of the operating parameters of the inert gas protection drying device according to the state of the positive and negative electrode materials during the return of the positive and negative electrode materials of the battery is an important problem in the battery recycling process.
