Electrochemical properties of Nano-LiFePO₄ prepared by hydrothermal reaction

Abstract

LiFePO₄ nanorods were facilely synthesized under hydrothermal condition. The crystalline structure and particle morphology of LiFePO₄ powders were characterized by X-ray diffraction (XRD), and field emission scanning electron microscopy (FE-SEM). The electrochemical properties of LiFePO₄/Li cells were investigated by galvanostatic test and cyclic voltammetry (CV). The XRD result demonstrated LiFePO₄ powder had an orthorhombic structure with a space group of Pnma. The synthesized LiFePO₄ nanorods exhibited a first discharge capacity of 155 mAh·g⁻¹ (91% of theorectical capacity) close to the theorectical capacity of LiFePO₄ (170 mAh · g⁻¹) at 0.1 C.
