Recently, LiFePO4 has drawn much attention as a promising cathode active material for lithium ion batteries. LiFePO4 is inexpensive, safe, environmental friendly, and the synthetic routes have been well established. However, the low electronic conductivity and low lithium ion diffusion of LiFePO4 greatly hinders its further development. In this study, the enhancement of the electrochemical properties of LiFePO4 has been carried out using different synthetic parameters such as different ball-milling time, magnesium doping (0.3%) and carbon coating(0, 3, 5%). |
