摘要：

A novel yolk-shell structured Co3O4-CoO/Carbon (Co3O4-CoO/C) composite was prepared and applied as cathode active materials in lithium ion batteries. The composites were prepared through a facile copolymerization of ionic liquid and acrylonitrile, which were used as carbon sources, followed by carbonization. The yolk-shell structure of the composite endows the electrodes with excellent cycling performance due to improved electronic conductivity, reduced strain and depressed aggregation of active materials compared with bare Co3O4. Thus, the Co3O4-CoO/C composite showed a high reversible capacity and cycling life of 590 mAh.g(-1) after 50 charge/discharge cycles at a current rate of 890 mAh.g(-1).
