Abstract

Est divulgué un procédé de récupération d'une poudre de batterie par désorption par pyrolyse à basse température, consistant à : permettre la réaction d'un matériau broyé de batterie usagée dans une atmosphère mixte, sous une pression d'air de 3 à 8 MPa, et à une température de 120 à 150 °C, l'atmosphère mixte étant un gaz mixte de CO<sub>2</sub>, NO et O<sub>2</sub>; permettre la réaction du produit de réaction obtenu sous une pression négative et à une température de 310 à 360 °C; puis effectuer un tri pour obtenir une feuille de cuivre-aluminium et une poudre de batterie. Selon la présente invention, un processus combiné de pyrolyse à haute pression et à basse température et de pyrolyse à pression négative et à température moyenne est utilisé, et la température de l'ensemble du processus est régulée pour être inférieure ou égale à 400 °C, de telle sorte que l'objectif de séparation d'un collecteur de courant peut être atteint; la scission de chaîne d'un polymère est obtenue, et l'oxydation du cuivre et de l'aluminium est évitée.Disclosed is a method for recovering a battery powder by low-temperature pyrolysis desorption, comprising: allowing a used battery crushed material to react in a mixed atmosphere under an air pressure of 3-8 MPa and a temperature of 120-150°C, the mixed atmosphere being a mixed gas of CO2, NO and O2; allowing the obtained reaction product to react under a negative pressure and a temperature of 310-360°C; and then performing sorting to obtain a copper-aluminum foil and a battery powder. According to the present invention, a combined process of high-pressure low-temperature pyrolysis and negative-pressure medium-temperature pyrolysis is used, and the temperature of the entire process is controlled to be 400°C or lower, so that the purpose of separating a current collector can be achieved; chain scission of a polymer is achieved, and oxidation of copper and aluminum is avoided.
