چکیده انگلیسی
LiNi0.4Co0.2Mn0.4O2 material synthesized at different temperatures by using LiNO3-LiCl and LiNO3-KNO3 molten salt as a reaction medium. The phase purity of the samples obtained by powder X-ray diffraction measurement which suggests layered α-NaFeO2 type is obtained at 800-900 °C using LiNO3-LiCl flux and at 750-850 °C using LiNO3-KNO3 flux. The surface morphology change with flux media at different temperature are obtained by scanning electron microscopy analysis. The galvanostatic cycling results show that the high stable reversible discharge capacity of 155 (±3) mAh gâ1 obtained for treated compound at 900 °C for 1 h (using LiNO3-LiCl) with coloumbic efficiency of 99%. The reversible discharge capacity of 140 and 130 (±3) mAh gâ1 obtained for treated compound at 750 and 850 °C, respectively (using LiNO3-KNO3).
