Leaching study of spent Li-ion batteries

摘要：

　　In order to investigate the characteristics of spent Li-ion batteries in acid leaching,the alkaline leaching residue was act as raw material.The effect of leaching rate was examined by XRD,SEM and ICP-AES.At last,the enlarged experiment was conducted.The results indicated that,in this experimental research scope,the best condition is 3 mol·L-1 H2SO4,15∶1 of liquid/solid,0.25 mol · L-1 Na2S2O3,90 ℃,3 h.According to the enlarged experiment,conducted at the best conditions,the main phase of raw materials is LiCoO2 and C,and the main phase of pickling residues is C.Co recycling rate was up to 99.95%,and Li leaching rate was up to 99.71%.
