摘要：

The ZnO/reduced graphene oxide (rGO) composites were deposited directly on nickel foam current collectors by electrostatic spray deposition technique. The morphology and crystal structure of as-deposited samples were characterized by scanning electron microscopy and X-ray diffraction, respectively. Their electrochemical properties were investigated by galvanostatic cycling and cyclic voltammograms tests. The electrochemical measurement results showed that ZnO/rGO composite films possessed a high and stable specific capacity. After rate capability test for 200 cycles, the ZnO/rGO composites still exhibited a specific capacity of 360 mAh g(-1) on average at current density of 0.2 A g(-1). The enhanced electrochemical performances of ZnO/rGO composite films might be derived from nano-enabled structures and enhanced kinetics by introduction of reduced grapheme oxides.
