| 摘 要： | 采用盐酸和双氧水体系为浸取液对废旧锂离子电池正极进行还原处理。正交实验表明,影响Co2+浸出率几种因素强度顺序为:HC l浓度>固液比>H2O2-HCl体积比>反应温度>反应时间。最佳浸取条件为:HCl浓度为3 mol/L,H2O2-HCl体积比为1∶15,反应时间90 min,反应温度80℃,固-液比(g/mL)为1∶50。此时,Co2+浸出率达到99.6%。

| Abstract: | The cathodes of spent lithium-ion batteries were treated by using hydrochloric acid and hydrogen peroxide system.The orthogonal tests showed that the intensity order of several factors influencing Co2+ leaching efficiency was HCl concentration>solid-liquid ratio>H2O2-HCl volume ratio>reaction temperature>reaction time.The experimental results indicated that the Co2+ leaching efficiency of 99.6% could be achieved when the optimum leaching conditions were 3 mol/L HCl,1 ∶15 of H2O2-HCl volume ratio,90 min of reaction time,80 ℃ of reaction temperature and 1 ∶50 of solid-liquid ratio(g/mL). |
