Supercapacitors based on nanostructured vanadium nitride/carbon nanotubes composites and thin films

摘要

Recently, vanadium nitride has attracted great attention as a promising material for supercapacitor applications due to its high theoretical capacitance. The few works on this subject highlighted several drawbacks of this material (capacitance fading with increasing sweeping rate, low conductivity...)[1,2]. The aim of this work is to improve the electrochemical properties of VN by using carbon nanotubes.
