英文摘要 | Assembled porous flower-like structures of ZnCo2O4 and ZnCo2O4@C products are prepared by a facile mediated solvothermal process combining with a calcination process. The as-prepared products are characterized by X-ray powder diffractometer (XRD), field emission scanning electron microscopy (FESEM), and transmission electron microscope (TEM). The samples are tested as anode materials for lithium-ion batteries. The results demonstrate that the introduction of C has a significant impact on the morphology and electrochemical performance of the samples. The porous microstructure ZnCo2O4@C composites can provide more contact between Li+ and electrodes and more effective electron transmission than pure ZnCo2O4. When tested as anode materials for lithium-ion batteries, the ZnCo2O4@C composites show a high specific capacity of similar to 760.3 mAh/g at a current rate of 0.1C after 100 cycles. This work would be significance of the preparation of complex oxides/carbon composites with porous microstructure as anodes for lithium-ion batteries. |
