We have studied the Li-diffusion coefficient values of electrospun Nb 2 O 5 nanofibers and nanonuggets for lithium batteries. In brief, Nb 2 O 5 nanofibers were prepared by electrospinning followed by sintering at temperatures range 500–1100°C for 1h in air to obtain pseudo-hexagonal, orthorhombic (O), and monoclinic (M) Nb 2 O 5 phases. Electrochemical...
Metal oxide nanostructures of wide bandgap semiconductors with various morphologies, high degree of crystallinity and surface properties were fabricated by electrospinning a polymeric solution containing respective metal ions and their controlled heat treatment. The metal oxide nanostructures thus developed were tested for their application as charge separation and transport medium in solar cells,...
In this work, bare and Ta-substituted Nb 2 O 5 nanofibers are prepared by electrospinning followed by sintering at temperatures in the 800–1100°C range for 1h in air. Obtained bare and Ta-substituted Nb 2 O 5 polymorphs are characterized by X-ray diffraction, scanning electron microscopy, density measurement, and Brunauer, Emmett and Teller surface area. Electrochemical...
