Abstract

Li[Ni_1/2Mn_1/2]O₂ material was synthesized by ultrasonic spray pyrolysis method. Li[Ni_1/2Mn_1/2]O₂ was characterized by means of X-ray diffraction, charge/discharge cycling, and cyclic voltammetry. The discharge capacities of Li/Li[Ni_1/2Mn_1/2]O₂ cell at 30 and 55°C slowly decreased with cycling and remained at 166 and 175 mAh/g after 50 cycles, which are 99 and 94% of initial capacities, respectively. The cyclic voltammogram studies of the Li[Ni_1/2Mn_1/2]O₂ electrode showed only one redox peak. This phenomenon might be related to the initial activation process and/or stabilization of Li[Ni_1/2Mn_1/2]O₂ electrode.
