Abstract

The spherical FePO_(4)·xH_(2)O was prepared in the solution by controlled crystallization.The precursor FePO_(4)was obtained in high temperatureceramic approach,then the high density LiFePO_(4)/C was synthesized by microwave carbon thermal reduction.The structure and morphology of the materials were characterized by means of XRD and SEM techniques,and the electrochemical properties were studies by charge-discharge experiments.
