In this work, we report the synthesis of spherical Cu 2 O through a facile and template-free solutionbased chemical precipitation method at 60°C. The crystal structure, surface morphology, and electrochemical performance of spherical Cu 2 O were investigated using X-ray diffraction, scanning electron microscopy, galvanostatic charge/discharge and cyclic voltammetry techniques, respectively. As anode materials for lithium-ion batteries, spherical Cu 2 O not only exhibits high cycling stability but also excellent reversibility.
