KINETIC MECHANISM OF LEACHING LITHIUM COBALT OXIDES USING TARTARIC ACID

  • 摘要: 提出了一种绿色回收废旧钴酸锂电池正极活性物质的方法。采用酒石酸为浸出剂和还原剂,湿法回收废旧钴酸锂电池中的钴和锂。结果表明:钴酸锂与酒石酸摩尔比为1∶4,反应固液比为15 g/L,反应温度为90℃,反应时间为5 h时,金属钴和锂的浸出率分别为92.95%、91.86%;动力学分析显示,Co、Li浸出反应利用经典模型拟合效果最佳,其表观活化能分别为55.20,63.65 kJ/mol,浸出过程属于吸热反应和化学反应控制。该工艺可实现废旧钴酸锂正极活性物质的高效绿色回收,为其他废旧锂离子电池的回收提供理论基础。
