Facile Synthesis of Magnesiated α-MoO3 and Its Electrochemical Performance in Li-Ion Batteries
Abstract:A facile approach has been developed for the synthesis of layered structure of magnesiated α-MoO3 based on the precipitation reaction, in which α-MoO3 nanoneedles were prepared as intermediates. The layered magnesiated α-MoO3 has been characterized by X-ray powder diffraction (XRD) and scanning electron microscopy (SEM). And the electrochemical performance as cathode materials in Li-ion battery shows that the magnesiated α-MoO3 had a capacity of 300 mAh·g−1 at the first discharge and a fairly good cycle performance at the current density of 200 mA·g−1. The great improvement indicates that the magnesiation method is an effective way to enhance electrochemical performance for the layered cathode materials.
