Abstract

Disclosed is a method for recovering battery powder by low-temperature pyrolysis desorption, comprising: enabling reaction of a waste battery crushed material in a mixed atmosphere, under an air pressure of 3-8 MPa, and at a temperature of 120-150°C, the mixed atmosphere being mixed gas of CO2, NO, and O2; enabling reaction of the obtained reaction product under a negative pressure and at a temperature of 310-360°C; and then sorting to obtain copper-aluminum foil and battery powder. According to the present invention, a combined process of low-temperature high-pressure pyrolysis and medium-temperature negative-pressure pyrolysis is used, and the temperature of the whole process is controlled to be 400°C or below, such that the purpose of separating from a current collector can be achieved; chain scission of a polymer is achieved, and oxidation of copper and aluminum is avoided.
