Abstract
In this paper, LiNi1/3Co1/3Mn1/3O2 was prepared via a facile rheological phase reaction method. The effect of synthesis temperature and holding time on its electrochemical performance has been investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), cyclic voltammetry (CV) tests and galvanostatic charge–discharge tests. The results suggest that the synthesis temperature and holding time greatly affect the electrochemical performance of the LiNi1/3Co1/3Mn1/3O2 and the optimized synthesis condition for the synthesis of LiNi1/3Co1/3Mn1/3O2 via rheological phase reaction method is 900 °C for 8 h. The obtained sample possesses a highly ordered layered structure and low cation mixing. It delivers an initial discharge capacity of 198 mAh g-1 at 0.2 C and 140 mAh g-1 at 1.0 C between 2.5 and 4.6 V, respectively.
