Aiming at the issues of strong corrosiveness and environmental pollution associated with traditional inorganic acid leaching methods for recovering cathode powder from spent lithium iron phosphate batteries. The ultrasonic-enhanced leaching of lithium and iron from spent lithium iron phosphate battery cathode powder using a mixture of organic acids such as gluconic acid and tartaric acid as the leaching agent and 3 mol/L hydrogen peroxide as the oxidant was investigated. The effects of ultrasonic power, gluconic acid concentration, tartaric acid concentration, leaching time and leaching temperature on the leaching rates of lithium and iron were examined. The results show that the leaching rate of lithium and iron reach 99.1% and 2.5%, respectively, under the optimal conditions of gluconic acid concentration of 0.5 mol/L, tartaric acid concentration of 1 mol/L, ultrasound power of 600 W, liquid volume to solid mass ratio of 6∶1, leaching time of 90 min and leaching temperature of 60 ℃. Ultrasonic intensification has little effect on the chemical composition of the leaching residue. After heat treatment, the leaching residue forms iron phosphate with good crystallinity. The leaching process is mainly controlled by chemical reactions, and the leaching effect is good.

针对传统无机酸浸出法回收废旧磷酸铁锂电池正极粉末存在的强腐蚀性与环境污染等问题,研究了以葡萄糖酸、酒石酸混合有机酸为浸出剂、3 mol/L过氧化氢为氧化剂,超声强化浸出废旧磷酸铁锂电池正极粉末中的锂和铁。考察了超声波功率、葡萄糖酸浓度、酒石酸浓度、浸出时间、浸出温度对锂、铁浸出率的影响。结果表明:在葡萄糖酸浓度0.5 mol/L、酒石酸浓度1.0 mol/L、超声波功率600 W、液固质量体积比6∶1、浸出时间90 min、浸出温度60 ℃最佳条件下,锂、铁浸出率分别为99.1%与2.5%;超声强化对浸出渣的化学成分无明显影响,浸出渣经热处理后,形成了结晶度较好的磷酸铁,浸出过程主要受化学反应控制,浸出效果较好。

针对传统无机酸浸出法回收废旧磷酸铁锂电池正极粉末存在的强腐蚀性与环境污染等问题,研究了以葡萄糖酸、酒石酸混合有机酸为浸出剂、3 mol/L过氧化氢为氧化剂,超声强化浸出废旧磷酸铁锂电池正极粉末中的锂和铁。考察了超声波功率、葡萄糖酸浓度、酒石酸浓度、浸出时间、浸出温度对锂、铁浸出率的影响。结果表明:在葡萄糖酸浓度0.5 mol/L、酒石酸浓度1.0 mol/L、超声波功率600 W、液固质量体积比6∶1、浸出时间90 min、浸出温度60 ℃最佳条件下,锂、铁浸出率分别为99.1%与2.5%;超声强化对浸出渣的化学成分无明显影响,浸出渣经热处理后,形成了结晶度较好的磷酸铁,浸出过程主要受化学反应控制,浸出效果较好。

Aiming at the issues of strong corrosiveness and environmental pollution associated with traditional inorganic acid leaching methods for recovering cathode powder from spent lithium iron phosphate batteries. The ultrasonic-enhanced leaching of lithium and iron from spent lithium iron phosphate battery cathode powder using a mixture of organic acids such as gluconic acid and tartaric acid as the leaching agent and 3 mol/L hydrogen peroxide as the oxidant was investigated. The effects of ultrasonic power, gluconic acid concentration, tartaric acid concentration, leaching time and leaching temperature on the leaching rates of lithium and iron were examined. The results show that the leaching rate of lithium and iron reach 99.1% and 2.5%, respectively, under the optimal conditions of gluconic acid concentration of 0.5 mol/L, tartaric acid concentration of 1 mol/L, ultrasound power of 600 W, liquid volume to solid mass ratio of 6∶1, leaching time of 90 min and leaching temperature of 60 ℃. Ultrasonic intensification has little effect on the chemical composition of the leaching residue. After heat treatment, the leaching residue forms iron phosphate with good crystallinity. The leaching process is mainly controlled by chemical reactions, and the leaching effect is good.
