Abstract

The kilogram-scale fabrication of V₆O₁₃ cathode materials has been notably assisted by in situ thermal gravimetric analysis (TGA)-infrared spectroscopy (IR) technology. This technology successfully identified a residue of ammonium metavanadate in commercial V₆O₁₃, which is consistent with the X-ray photoelectron spectroscopy result. Samples of V₆O₁₃ materials have been fabricated and characterized by TGA-IR, scanning electron microscopy, and X-ray diffraction. The initial testing results at 125 °C have shown that test cells containing the sample prepared at 500 °C show up to a 10% increase in the initial specific capacity in comparison with commercial V₆O₁₃.
