Abstract
In this work, cuprous oxide/reduced graphene oxide (Cu2O/RGO) composite was successfully synthesized by a low-cost, facile, green, solution-based chemical method. The as-synthesized products were characterized by X-ray powder diffraction (XRD). As anode materials for lithium ion batteries, the results show RGO can enhance the conductivity of Cu2O, as well as relieve the volume expansion/contraction. Therefore, Cu2O/RGO composite shows high capacity retention, high reversible capacity and excellent cycling stability.
