A phosphoric acid - ammonium sulfite leaching system was employed to leach valuable metal elements such as nickel, cobalt and manganese from cathode materials of spent ternary lithium-ion batteries. The effects of phosphoric acid concentration, concentration of ammonium sulfite monohydrate, temperature and time of reaction on the total leaching rate of valuable metals were investigated. It is found that with phosphoric acid at the concentration of 0.8 mol/L, ammonium sulfite monohydrate at the concentration of 25 g/L, reaction at 70 ℃ for 90 min can result in the total leaching rate of valuable metals up to 95.2%. After the acid leaching process is kinetically fitted using the shrinking unreacted core model, it is shown that the leaching process is controlled by surface chemical reaction.

采用磷酸-亚硫酸铵浸出体系从退役三元锂离子电池正极材料中浸出镍、钴、锰等有价金属元素,考察磷酸浓度、一水亚硫酸铵质量浓度、反应温度、反应时间等因素对有价金属元素复合浸出率的影响。结果表明,在磷酸浓度0.8 mol/L、一水亚硫酸铵质量浓度25 g/L、反应温度70 ℃、反应时间90 min条件下,有价金属元素复合浸出率达95.2%。对酸浸过程进行了未反应收缩核模型拟合,结果显示,浸出过程受表面化学反应控制。

采用磷酸-亚硫酸铵浸出体系从退役三元锂离子电池正极材料中浸出镍、钴、锰等有价金属元素,考察磷酸浓度、一水亚硫酸铵质量浓度、反应温度、反应时间等因素对有价金属元素复合浸出率的影响。结果表明,在磷酸浓度0.8 mol/L、一水亚硫酸铵质量浓度25 g/L、反应温度70 ℃、反应时间90 min条件下,有价金属元素复合浸出率达95.2%。对酸浸过程进行了未反应收缩核模型拟合,结果显示,浸出过程受表面化学反应控制。

A phosphoric acid - ammonium sulfite leaching system was employed to leach valuable metal elements such as nickel, cobalt and manganese from cathode materials of spent ternary lithium-ion batteries. The effects of phosphoric acid concentration, concentration of ammonium sulfite monohydrate, temperature and time of reaction on the total leaching rate of valuable metals were investigated. It is found that with phosphoric acid at the concentration of 0.8 mol/L, ammonium sulfite monohydrate at the concentration of 25 g/L, reaction at 70 ℃ for 90 min can result in the total leaching rate of valuable metals up to 95.2%. After the acid leaching process is kinetically fitted using the shrinking unreacted core model, it is shown that the leaching process is controlled by surface chemical reaction.
