Application of Low Temperature Molten Salt Synthesis (LT-MSS) Method in Preparation of Fibrous AgVO₃ as Cathode Material for Lithium Battery

Abstract

One-dimensional (1D) nanostructured β-AgVO₃ fibers have been successfully synthesized at 300°C for 3 h via the low-temperature molten salt synthesis (LT-MSS) method where LiNO₃ was employed as reaction media. The crystal structure and morphology of the as-obtained β-AgVO₃ fibers were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. The results revealed that the LT-MSS product displayed a high crystallinity and consisted of fibrous crystals with widths of 150 nm to 1 µm and lengths of several to several tens of micrometers. Electrochemical measurements indicated that the as-synthesized β-AgVO₃ fibers exhibited higher discharge capacity and better cycleability compared with the counterparts from the liquid phase synthesis (LPS) and the high temperature solid state synthesis (HT-SSS) methods.
