Fabrication of VOx embedded porous carbon nanofibrous structures and its probable application as anode for LiBs

Abstract

Porous nanofibers are explored due to its applications in various fields such as water remediation, biomedicalengineering, healthcare, and in various energy storage systems. Vanadium Oxide (VOx) embedded porous carbon nanofibers is considered as an optimistic material for a broad spectrum of applications due to its intriguing physico-chemical properties and the large surface areait possess. Here, we report on the fabrication of VOxembedded carboncomposite porous nanofibers and its electrochemical performance studies. The composite nanofibers of around 300 nm in diameter are synthesized via hydrothermal method followed by electrospinning and carbonization processes and characterised by XRD, FESEM, HRTEM and XPS techniques. The initial electrochemical performance studies carried out using 2032 type coin cell configuration confirm that VOx embedded carbon composite nanofibers could be a highly promising candidate as an anode material for Lithium-ion batteries.
