摘要: Abstract Nanospheres of CuO are synthesized by a facile solution reaction CuCl 2 in the presence carbon nanotubes (CNTs), yielding composite material. Transmission electron microscopy (TEM) confirms uniform dispersion nanospheres on CNTs surface. The functional groups determined Fourier transform infrared spectroscopy (FTIR) and elemental composition is confirmed Rutherford backscattering (RBS), while structure morphology deposited electrodes investigated X-ray diffraction (XRD) scanning (SEM), respectively. Electrochemical characterization cyclic voltammetry (CV) galvanostatic charge/discharge tests demonstrate high rate capability superior cycling stability for CuO/CNT with specific capacity 638 mAh/g up to 50 cycles. It anticipated that this efficiency due excellent conductivity mesh.
