A processing technique of gas-solid chlorination combined with water leaching was adopted for systematically investigating the phase evolution of spent lithium iron phosphate (LFP) cathode material during recycling, and the dynamic mechanism of lithium extraction via gas-solid chlorination of spent LFP cathode material was also clarified. It is found that the chlorination reaction of spent cathode material can proceed spontaneously in thermodynamics, and lithium can be converted into water-soluble phases through the gas-solid chlorination process. Under the optimized conditions of gas-solid chlorination, including reaction temperature of 150 ℃ and reaction time of 156 min, LiFePO₄ is almost completely transformed into FePO₄ and LiCl by water leaching, presenting a leaching rate of lithium at 99.09%, while the leaching rates of iron, phosphorus and aluminum just 0.089%, 0.078% and 0.339%, respectively. This process actualizes efficient and highly selective leaching of lithium. Meanwhile, the crystal structure and morphology of FePO₄ are well maintained during chlorination and water leaching, providing a stable precursor for the subsequent solid-phase synthesis and regeneration of lithium iron phosphate.

采用气固氯化-水浸联合工艺，系统研究了废旧磷酸铁锂（LFP）正极材料在回收过程中的物相演变规律，阐明了废旧LFP气固氯化提锂过程的动态机制。结果表明，正极材料的氯化反应在热力学上可自发进行，采用气固氯化工艺，可将锂转变为水溶性物相。在反应温度150 ℃、反应时间156 min的气固氯化优化条件下，水浸时LiFePO₄几乎完全转化为FePO₄和LiCl，水浸的锂浸出率达99.09%，而铁、磷和铝浸出率分别仅为0.089%、0.078%和0.339%。该工艺不仅实现了Li的高效、高选择性浸出，而且在氯化和水浸过程中维持了FePO₄晶体结构和形貌的完整性，为后续固相合成再生磷酸铁锂提供了稳定前驱体。
