Ultra-thin CuO nanomaterial was easily prepared by calcining the copper hydroxide precursor which was obtained from solvent approach. The techniques of FT-IR spectroscopy, X-ray diffraction (XRD) and scanning electron microscope (SEM) were used to characterize the structure and morphology of annealed sample. The results demonstrate that material is expressed as uniform nanosheets whose thickness is about 5 nm. Theelectrochemical performances including cyclic voltammetric curves (CV), electrochemical impedance spectra (EIS), charge/discharge curves and cycling performances were also measured and analyzed. The discharge capacity of the CuO nanosheets in the first cycle canachieve 660 mAh g−1 with the coulombic efﬁciency of 60.6%. The discharge capacity maintained 320 mAh g−1 at a current density of 100 mA g−1 even after 50 cycles.
