Preparation of LiFePO4/graphene composites by microwave-assisted solvothermal method

Abstract

Well-crystallized and nano-sized LiFePO₄/graphene composite have been successfully synthesized by in-situ disperse graphene oxide (GO) in precursor via a rapid microwave-solvothermal process at 200°C within 10 min. In spite of the low synthesis temperature, the structural and morphological properties of as-prepared composites present high specific capacity, an excellent high rate capability, and stable cycling performance.The short reaction times of just 10 min show the basis for an efficient and time-saving synthesis of LiFePO₄ρaphene composite.
