| 摘 要： | 综合运用XRD、ICP及TOC表征破碎废旧锂离子电池筛分后得到的电极材料成分,并利用TGA、GC-MS对电极材料的碳热还原反应机理进行探究。在无氧焙烧条件下,废旧锂离子电池中的负极材料石墨与正极材料钴酸锂发生反应,得到产物钴与碳酸锂,经湿式磁选分离后,钴以单质形式富集在磁性固体中,钴回收率为95.12%。

| Abstract: | XRD, ICP and TOC were applied to characterize electrode materials obtained by sieving of waste Li-ion batteries. The mechanisms of carbon thermal reduction were investigated by TGA and GC-MS under oxygen-free condition. Under the condition of oxygen-free roasting, anode material graphite in waste lithium-ion battery reacts with cathode material to obtain products of cobalt and lithium carbonate. Cobalt is present in magnetic solid after wet magnetic separation with final recovery rate of 95.12%. |
