Hydrothermal Synthesis and Electrochemical Performance of LiFePO₄/Graphene Composites for Lithium-Ion Batteries

Abstract:

LiFePO₄/graphene composites were prepared via a simple hydrothermal method. The as-prepared LiFePO₄/graphene composites were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), galvanostatic charge-discharge test, cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) tests. The lithium-ion batteries using LiFePO₄/graphene composites as cathode material exhibited a discharge capacity of 165 mAh/g, which was 97% of the theoretical capacity of 170 mAh/g.
