采用简单的湿化学方法合成了硫化铜(cu)-还原氧化石墨烯（rGO）复合材料。通过x射线衍射、扫描电镜和透射电镜技术对样品进行了表征。研究了层次化cu - rgo复合材料作为锂离子电池负极材料的电化学性能，并与纯cu进行了比较。结果表明，层次化cu - rgo复合材料的100次循环比容量为408 mAh/g，循环稳定性高于纯cu。
Hierarchical copper sulfide (CuS)-reduced graphene oxide (rGO) composites were synthesized using a simple wet chemical method. The samples were characterized via X-ray diffraction, scanning electron microscopy, and transmission electron microscopy techniques. The electrochemical performances of hierarchical CuS-rGO composites, as anode materials for lithium-ion batteries, were also investigated in comparison with that of pure CuS. Results showed that the specific capacity of 408 mAh/g after 100 cycles and cycling stability of hierarchical CuS-rGO composites were higher than those of pure CuS.
