摘　　要：为探究新能源汽车废旧电池最优回收条件,以某新能源汽车的废旧电池作为回收对象,分析不同回收条件下最优的金属浸出率。设置测试电池,选择回收方法、实验试剂与仪器,设计回收流程。设置三因素三水平正交实验,研究上述不同方法的操作性和回收率。实验结果表明,Li的浸出率为99.64%,操作性强,回收率高。对应实验条件为:处理阶段:混合磨制设备转数600转/分、共磨剂与物料比例1:10、共磨混合时间30分钟。回收阶段:浸出剂添加比例4%、浸出剂与溶液比例1:30,操作温度为70℃、反应时间为50分钟。在上述条件下,硫酸铵作为共磨剂浸出效果最好。To explore the optimal recycling conditions for waste batteries from new energy vehicles,a waste battery from a certain new energy vehicle was used as the recycling object to analyze the optimal metal leaching rate under different recycling conditions.The study set up test batteries,selected recycling methods,experimental reagents and instruments,and designed the recycling processes.A three factor and three level orthogonal experiment was conducted to study the operability and recovery rate of the different methods mentioned above.The experimental results show that the leaching rate of Li is 99.64%,with strong operability and high recovery rate.The corresponding experimental conditions are:processing stage:mixed grinding equipment speed of 600 revolutions per minute,co grinding agent to material ratio of 1:10,and co grinding mixing time of 30 minutes.The addition ratio of leaching agent is 4%,the ratio of leaching agent to solution is 1:30,the operating temperature is 70℃,and the reaction time is 50 minutes.Under the above conditions,ammonium sulfate as a co grinding agent has the best leaching effect.
