LiMn₂O₄ Prepared by Liquid Phase Flameless Combustion with F-Doped for Lithium-Ion Battery Cathode Materials

Abstract:

LiMn₂O_4-yF_y were synthesized by a novel method named liquid phase flameless combustion reaction with LiNO₃, MnAc₂.4H₂O and LiF as raw materials calcined at 600 °C for 3 h with HNO₃ as aided oxidant. All samples were investigated by X-ray diffraction (XRD), fourier transform infrared spectroscopy (FTIR) and electrochemical performance. The results show that: all samples have main phase of LiMn₂O₄ with impurity of Mn₃O₄ and the vibrational bands of Mn-O are a little red shift by doping F, which indicated that the F- enter the host structure of LiMn₂O₄ successfully. The electrochemical performance show that the initial discharge capacities of F-doped samples are lower than pristine LiMn₂O₄, which is 117.7 mAh•g^-1. However, the capacity retention of LiMn₂O_3.96F_0.04 and LiMn₂O_3.90F_0.10 are 73.6% and 74.5%, respectively, which are higher than pristine LiMn₂O₄, which is only 69.0% after 40 cycles.
