Abstract

LiNi _0.4 Co _0.2 Mn _0.4 O ₂ material synthesized at different temperatures by using LiNO ₃ -LiCl and LiNO ₃ -KNO ₃ molten salt as a reaction medium. The phase purity of the samples obtained by powder X-ray diffraction measurement which suggests layered α-NaFeO ₂ type is obtained at 800–900 °C using LiNO ₃ -LiCl flux and at 750–850 °C using LiNO ₃ -KNO ₃ 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 g ⁻¹ obtained for treated compound at 900 °C for 1 h (using LiNO ₃ -LiCl) with coloumbic efficiency of 99%. The reversible discharge capacity of 140 and 130 (±3) mAh g ⁻¹ obtained for treated compound at 750 and 850 °C, respectively (using LiNO ₃ -KNO ₃ ).
