High efficient and selective recovery of lithium from spent LiFePO4 batteries by hydrogen peroxide oxidative leaching method was studied. The effects of hydrogen peroxide concentration, solid mass to liquid volume ratio, leaching temperature and time on the leaching behavior of lithium were examined. Kinetic analysis, XRD and SEM were used to investigate the leaching mechanism. The results show that under the optimal conditions of hydrogen peroxide concentration of 20%, solid mass to liquid volume ratio of 3 mg/1 mL, leaching temperature of 40 ℃ and leaching time of 40 min, the leaching rate of lithium can reach 99%, while the leaching rate of iron is only 0.53%, and the leaching process is mainly controlled by internal diffusion. The method can provide technical support for the efficient selection and recovery of lithium in spent LiFePO4 batteries.

研究了采用过氧化氢氧化浸出法从废旧磷酸铁锂电池中高效选择性回收锂,考察了过氧化氢浓度、固液质量体积比、浸出温度和时间对锂浸出行为的影响,并采用动力学分析、XRD和SEM表征技术探讨了浸出机制。结果表明:在过氧化氢浓度20%、固液质量体积比3 mg/1 mL、浸出温度40 ℃、浸出时间40 min优化条件下,锂浸出率达99%,而铁浸出率仅为0.53%,实现了锂的高效浸出,该浸出过程主要受内扩散控制。该法可为废旧磷酸铁锂电池中锂的高效选择回收提供技术支持。

研究了采用过氧化氢氧化浸出法从废旧磷酸铁锂电池中高效选择性回收锂,考察了过氧化氢浓度、固液质量体积比、浸出温度和时间对锂浸出行为的影响,并采用动力学分析、XRD和SEM表征技术探讨了浸出机制。结果表明:在过氧化氢浓度20%、固液质量体积比3 mg/1 mL、浸出温度40 ℃、浸出时间40 min优化条件下,锂浸出率达99%,而铁浸出率仅为0.53%,实现了锂的高效浸出,该浸出过程主要受内扩散控制。该法可为废旧磷酸铁锂电池中锂的高效选择回收提供技术支持。

High efficient and selective recovery of lithium from spent LiFePO4 batteries by hydrogen peroxide oxidative leaching method was studied. The effects of hydrogen peroxide concentration, solid mass to liquid volume ratio, leaching temperature and time on the leaching behavior of lithium were examined. Kinetic analysis, XRD and SEM were used to investigate the leaching mechanism. The results show that under the optimal conditions of hydrogen peroxide concentration of 20%, solid mass to liquid volume ratio of 3 mg/1 mL, leaching temperature of 40 ℃ and leaching time of 40 min, the leaching rate of lithium can reach 99%, while the leaching rate of iron is only 0.53%, and the leaching process is mainly controlled by internal diffusion. The method can provide technical support for the efficient selection and recovery of lithium in spent LiFePO4 batteries.
