摘要：

A new LiCoO2 recovery technology of Li-ion battery was studied. LiCoO2 was initially separated from the Al foil with dimethyl acetamide(DMAC), and then the polyvinylidene fluoride(PVDF) and carbon powders in the active material were eliminated by high temperature calcining. The content of the elements in the recovered powder was analyzed. The structure and morphology of the resulted samples were observed by XRD and SEM. Then the Li2CO3 was added in the recycled powder to adjust the Li/Co molar ratio to 1. The new LiCoO2 was synthesized by calcining at 850 V for 12 h in air. The well-crystallized single phase LiCoO2 without Co3O4 phase was obtained. The recycle-synthesized LiCoO2 powders have good characteristics as a cathode active material in terms of charge-discharge capacity and cycling performance.
