Summary: | Pure lithium iron phosphates and stoichiometric Cu-doped lithium iron phosphates were synthesized via improved co-precipitation, followed by sintering at high temperature for crystallization. The improved co-precipitation process allowed the homogeneous mixing of the ingredient reactants at atomic level. All samples were pure single phase indexed with orthorhombic Pnmb space group. The particle size of the Li0.98Cu0.01FePO4 was drastically fine with100 -200 nm, compared with the undoped LiFePO4. The electrochemical performance of Li0.98Cu0.01FePO4, including reversible capacity, cycle number and charge -discharge characteristics, exhibited better than those of LiFePO4. |
