英文摘要: Abstract(#br)The recycling of spent commercial lithium-ion batteries (LIBs) generates numerous environmental and economic benefits. In this research, a thermal treatment-ammoniacal leaching process is proposed to recover valuable metals from cathode active powder. Based on the thermal behavior by TG-DSC analysis, the cathode active powder is calcined at 300 °C and 550 °C in air atmosphere, and the crystalline phase characterization indicates that a new phase of Co 3 O 4 appears in the cathode active powder calcined at 550 °C, which signifies that the layer structure of LiCoO 2 collapses. The valence of manganese increases to form Li 4 Mn 5 O 12 in spinel structure of LiMn 2 O 4 . Using calcined cathode powder as feed material, ammoniacal leaching is carried out in (NH 4 ) 2 SO 4 -(NH 4 )...
