摘要：
The porous copper oxide (CuO)/reduced graphene oxide (rGO) composite was prepared by hydrothermal procedure and stirred with graphene oxide dispersion. The composite was employed as anode material to prepare a lithium-ion battery. The effects of different copper sources on the morphology and chemical properties of the materials were studied. Our findings revealed that the structure of CuO with different morphologies was significantly different, which changed the bonding mode of CuO/ RGO composites. Our study discovered that the thorn-like B and spherical A and D possess greater capacity and cycle stability. After 100 charge-discharge processes with 200 mAg(-1) current density, the reversible capacities were 295 mAhg(-1), 290 mAhg(-1), and 313mAhg(-1).
