A technique combining mechanical force and heating effect was adopted to selectively disassociate cathode material from spent lithium-ion batteries and roll the aluminum foil by adjusting processing parameters. The results show that a better disassociation effect can be obtained with the frequency of electric motor, air circulation fan and dissociation device at 40 Hz, 40 Hz and 50 Hz, respectively. The aluminum foil with particle size of -1.7+0.075 mm is rolled to be spherical, and the cathode materials with particle size of -0.075+0.048 mm and -0.048 mm are rough on the surface and wrapped by organic binder. The final dissociation rate of cathode sheet can be up to 96.35%, and the cathode material can be recovered at a rate of 94.95% by single operation, with the content of Al impurity less than 0.15%. It is shown that this selective dissociation technique based on a combination of mechanic force and heating effect can actualize an efficient separation and sorting of cathode sheet, not only shortening the battery disposal process flow but also achieving efficient metal enrichment.

采用机械力和温度耦合作用的解离技术,通过调控选择性解离工艺参数,使正极材料脱落,同时铝箔球化。结果表明,喂料电机频率40 Hz、循环风机频率40 Hz、解离设备频率50 Hz时,选择性解离效果较好,-1.7+0.075 mm粒级铝箔实现球化,-0.075+0.048 mm粒级和-0.048 mm粒级正极材料颗粒表面粗糙,被有机黏结剂包裹,最终得到正极片解离率为 96.35%、正极材料单次回收率为94.95%、Al杂质含量小于0.15%的指标。基于机械力和温度耦合的选择性解离技术能够实现正极片的高效分离分选,缩短电池处理流程,实现金属高效富集。

采用机械力和温度耦合作用的解离技术,通过调控选择性解离工艺参数,使正极材料脱落,同时铝箔球化。结果表明,喂料电机频率40 Hz、循环风机频率40 Hz、解离设备频率50 Hz时,选择性解离效果较好,-1.7+0.075 mm粒级铝箔实现球化,-0.075+0.048 mm粒级和-0.048 mm粒级正极材料颗粒表面粗糙,被有机黏结剂包裹,最终得到正极片解离率为 96.35%、正极材料单次回收率为94.95%、Al杂质含量小于0.15%的指标。基于机械力和温度耦合的选择性解离技术能够实现正极片的高效分离分选,缩短电池处理流程,实现金属高效富集。

A technique combining mechanical force and heating effect was adopted to selectively disassociate cathode material from spent lithium-ion batteries and roll the aluminum foil by adjusting processing parameters. The results show that a better disassociation effect can be obtained with the frequency of electric motor, air circulation fan and dissociation device at 40 Hz, 40 Hz and 50 Hz, respectively. The aluminum foil with particle size of -1.7+0.075 mm is rolled to be spherical, and the cathode materials with particle size of -0.075+0.048 mm and -0.048 mm are rough on the surface and wrapped by organic binder. The final dissociation rate of cathode sheet can be up to 96.35%, and the cathode material can be recovered at a rate of 94.95% by single operation, with the content of Al impurity less than 0.15%. It is shown that this selective dissociation technique based on a combination of mechanic force and heating effect can actualize an efficient separation and sorting of cathode sheet, not only shortening the battery disposal process flow but also achieving efficient metal enrichment.
