dc.description.abstract | Li[Ni1/3Mn2/3]O-2 was synthesized by a self-combustion reaction (SCR), characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Raman spectroscopy, and studied as a cathode material for Li-ion batteries at 30 degrees C and 45 degrees C. The structural studies by XRD and TEM confirmed monoclinic Li[Li1/3Mn2/3]O-2 phase as the major component, and rhombohedral (LiNiO2), spinel (LiNi0.5Mn1.5O4), and rock salt Li0.2Mn0.2Ni0.5O as minor components. The content of the spinel phase increases upon cycling due to the layered-to-spinel phase transition occurring at high potentials. A high discharge capacity of about 220 mAh g1 is obtained at low rate (C/10) with good capacity retention upon cycling. However, LiNi0.5Mn1.5O4 synthesized by SCR exhibits a discharge capacity of about 190 mAh g(-1) in the potential range of 2.44.9 V, which decreases to a value of 150 mAh g(-1) after 100 cycles. Because of the presence of the spinel component, Li[Ni1/3Mn2/3]O-2 cathode material exhibits part of its capacity at potentials around 4.7 V. Thus, it can be considered as an interesting high-capacity and high-voltage cathode material for high-energy-density Li-ion batteries. Also, the Li[Ni1/3Mn2/3]O-2 electrodes exhibit better electrochemical stability than spinel LiNi0.5Mn1.5O4 electrodes when cycled at 45 degrees C. | en_US |
