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.

Key words: Lithium iron phosphate, Controlled crystallization, Microwave, Carbon thermal reduction
