Abstract

Manganese titanate (MnTiO3) powder was prepared via a sol-gel method using manganese acetate and tetrabutyl titanate as raw materials, and citric acid as a chelating agent. Through high temperature nitridation of MnTiO3 powder in ammonia, the MnO/TiN composite was obtained. The phase structure, composition and morphology of the composites were characterized by XRD, SEM and EDS. The electrochemical properties of the composite electrodes were studied by performing cyclic voltammetry, galvanostatic charge and discharge, and electrochemical impedance spectroscopy tests. The MnO/TiN electrode delivered specific capacities of 394 mAh?g-1 and 146 mAh?g-1 at the current density of 100 mA?g-1 and 1 A?g-1, respectively, and exhibited higher specific capacity and superior rate capability than MnO electrode, which can be ascribed to the presence of TiN in the composite offering an electron conducting network and suppressing the volume expansion of MnO efficiently during the charge and discharge processes.
