Influence of post-annealing in N₂ on structure and electrochemical characteristics of LiNi_0.5Mn_1.5O₄

Abstract

LiNi_0.5Mn_1.5O₄ prepared by a spray drying method was re-treated in N₂ at 500, 600 and 700 °C, respectively. Their structural and electrochemical properties were studied by means of Fourier transform infrared(FTIR), X-ray diffraction(XRD), and charge-discharge tests. The space group of the LiNi_0.5Mn_1.5O₄ transforms from P4₃32 to $Fd\bar 3m$ at an annealing temperature of 700 °C. The electrochemical characteristics of the treated samples are closely related to the annealing temperature. The sample treated in N₂ at 500 °C shows both an improved rate capability and cyclic performance at a high temperature compared with the as-prepared sample, while the sample treated in N₂ at 700 °C shows dramatically decrease in its reversible capacity.
