▎ 摘　　要

With the simultaneous reduction of Cu2+ ions and GO by ethylene glycol, this work explores the convenient and one-pot preparation of porous cuprous oxide nanoparticles on reduced graphene oxide (Cu2O-RGO). A series of measurements were applied for the characterization of the surface morphology, crystal structure and basic chemical elements of synthesized nanocomposite. An increase of initial discharge capacity to 2038 mAh/g was observed for the battery due to the synergetic effect of wrinkled graphene & copper oxide. This study conducts the impedance spectroscopy for obtaining charge transfer resistance of the electrode, with the results analysed herein.
