Embodiment 1
[0072] After the used-up waste products of commercially available lithium-ion batteries are discharged and detoxified by known methods, holes are punched in the battery case, and the electrolyte solution is removed therefrom. In addition, it used as a raw material as it is without separating a battery case etc.
[0073] Next, the detoxified lithium-ion battery waste (raw material) from which the electrolyte was removed was put into a converter in the copper smelting process and burned. Here, the state of the converter is the state before the usual treatment in the copper smelting process, that is, the state before the process of filling copper matte and blowing oxygen to generate blister copper. state. This converter is in a hot state through repeated operations in the copper smelting process. Therefore, the charged lithium-ion battery waste is combusted by residual heat.
[0074] In addition, assuming that the input amount of the lithium-ion battery scrap to the converter ...
