WASTE LITHIUM BATTERY RECYCLING PYROLYSIS TEMPERATURE CONTROL METHOD AND APPLICATION

The present invention relates to the technical field of battery pyrolysis, and discloses a waste lithium battery recycling pyrolysis temperature control method. The method comprises the following steps: mixing a waste battery raw material with a solid medium, and performing anaerobic pyrolysis, screening, crushing and sorting to obtain battery powder, the temperature of anaerobic pyrolysis being 350-550°C. By using the method of the present invention, the common problem of difficulty in pyrolysis temperature control in the battery recovery industry can be solved; and accurate temperature control is realized by using the solid medium, high impurity content in battery black powder caused by serious oxidation of copper and aluminum in a battery due to out-of-control temperature in a pyrolysis process is avoided, and meanwhile, the safety risk caused by out-of-control temperature is reduced. La présente invention concerne le domaine technique de la pyrolyse de batterie et divulgue un procédé de régulation de temp
