APPARATUS FOR ROASTING LITHIUM ION BATTERY WASTE

Provided is a waste lithium-ion battery roasting apparatus that makes it possible to improve heat treatment efficiency and to improve a useful metal recovery rate. One example of the waste lithium-ion battery roasting apparatus according to the present invention includes: a transport mechanism (4) including a cylindrical body (41) whose one end is a receiving inlet (41a) and whose another end is a discharging outlet (41b), the cylindrical body (41) containing an internal atmosphere that is a reducing atmosphere or a low-oxygen atmosphere, the transport mechanism (4) receiving a waste lithium-ion battery through the receiving inlet (41a), transporting the waste lithium-ion battery inside the cylindrical body (41) toward the discharging outlet (41b), and discharging the waste lithium-ion battery from the discharging outlet (41b); a heating mechanism (5) that heats an outer wall of the cylindrical body (41) to increase an internal temperature of the cylindrical body (41), and controls heating temperatures individually at which the heating mechanism heats the outer wall at different respective positions in a transporting direction in which the transport mechanism (4) transports the waste lithium-ion battery; and a controller (21) that controls the heating temperatures, at which the heating mechanism (5) heats the outer wall, in accordance with a transporting speed at which the transport mechanism (4) transports the waste lithium-ion battery, such that a temperature increase rate of the waste lithium-ion battery transported inside the cylindrical body is a predetermined temperature increase rate.
