Abstract (English): The phospho-glutathione system was used to study how phosphate and glutathione concentrations, leaching temperature, solid-liquid ratio, and leaching time affect the extraction of lithium, nickel, cobalt, and manganese from discarded ternary lithium-ion battery cathodes. The results show that under the conditions of 1 mol/L phosphate, 0. 03 mol/L glutathione, 55 ℃ leaching temperature, 35 g/L solid-liquid ratio and 60 min leaching time, the leaching rates of lithium, nickel, cobalt and manganese are above 98%. Glutathione play a role in reducing metal valence and releasing H+ to promote leaching during the reaction. The apparent activation energies of lithium, nickel, cobalt and manganese are calculated in the range of 37~42 kJ/mol by Arrhenius equation, indicating that the leaching process is controlled by chemical reaction.

Abstract (Chinese): 采用磷酸 - 谷胱甘肽体系浸出废旧三元锂离子电池正极材料中的有价金属, 探究磷酸浓度、谷胱甘肽浓度、浸出温度、固液比 和浸出时间对锂、镍、钴和锰浸出率的影响。结果表明, 在磷酸 1 mol/L、谷胱甘肽 0. 03 mol/L、浸出温度 55 ℃、固液比 35 g/L、浸出 时间60 min条件下, 锂、镍、钴和锰的浸出率均达到98%以上。谷胱甘肽在反应过程中起到了降低金属价态和释放H+ 促进浸出的作用。 采用收缩未反应核模型对各金属浸出率做动力学拟合, 由阿伦尼乌斯方程计算出锂、镍、钴和锰的表观活化能在 37~42 kJ/mol, 说明 浸出过程受化学反应控制。 [ABSTRACT FROM AUTHOR]
