Abstract:
Preparation of copper-indium-tin mixed oxide nanofibers (CuInSnO₄) via sol-gel and electrospinning methods at low temperature is the major research focus since the mixed metal oxides could help increasing the insertion of lithium ion into the lattice of CuInSnO₄ for a good electrochemical performance in Li-ion battery. In this study, poly(vinyl alcohol) or PVA is used to mix with those corresponding precursors for spinning nanofibers to increase surface area of the product. After calcinations, the CuInSnO₄ nanofibers were characterized by X-ray diffraction spectroscope (XRD) for the spinel phase analysis, scanning electron microscope (SEM) for the morphology investigation, and BET technique for surface area analysis.
