以废旧锂离子电池为原料，采用水热法制备出纳米晶钴铁氧体，讨论了在制备过程中加入添加剂对钴铁氧体磁性能的影响。借助于 XRD 对产物的制备过程进行了跟踪检测，并借助于 IR、TG、VSM等手段对产物进行了表征。结果表明加入适量冰乙酸有利于钴铁氧体的生成和磁性能的提高，但过量的冰乙酸的加入会使最终产物中含有乙酸根，同时也降低钴铁氧体的磁性能。而在沉淀过程中加入柠檬酸作添加剂则不利于钴铁氧体的生成。
以廢舊鋰離子電池為原料，採用水熱法製備齣納米晶鈷鐵氧體，討論瞭在製備過程中加入添加劑對鈷鐵氧體磁性能的影響。藉助于 XRD 對產物的製備過程進行瞭跟蹤檢測，併藉助于 IR、TG、VSM等手段對產物進行瞭錶徵。結果錶明加入適量冰乙痠有利于鈷鐵氧體的生成和磁性能的提高，但過量的冰乙痠的加入會使最終產物中含有乙痠根，同時也降低鈷鐵氧體的磁性能。而在沉澱過程中加入檸檬痠作添加劑則不利于鈷鐵氧體的生成。

Nano-crystal cobalt ferrite was synthesized from waste lithium ion batteries through a hydrothermal process.The effects of additives on the magnetic properties of Co-ferrite were studied.Their characterizations were investigated by X-ray diffraction (XRD),infrared spectrophotometer (IR),thermogravimetry (TG)and vibrating sample magnetometer (VSM).The results showed that cobalt ferrite was conducive to the generation and the improvement of magnetic properties by adding appropriate amount of glacial acetic acid,but excessive addition of glacial acetic acid would make the final product contain acetic acid roots,while also reducing the magnetic properties of cobalt ferrite.In the precipitation process,adding citric acid additives was not in favour of the formation of cobalt ferrite.
