Abstract
High-quality, reduced graphene oxide (RGO) homogeneously coated LiCo1/3Ni1/3Mn1/3O2 (NCM) was synthesized by ultrasonically mixing/stirring GO and NCM in water and then thermal reduction of GO to RGO. The composite NCM cathode shows much higher specific capacity, better cycling stability and high rate performance after being wrapped by RGO, which is attributed to the much lower electrochemical impedance for the electrode due to the presence of RGO. It is promising for RGO modified NCM to be used as an excellent cathode.This publication has 16 references indexed in Scilit:
