Abstract:
Recently metal oxide based supercapacitor has immense importance due to their
enhanced capacitive properties. Niobium Oxide (Nb2O5) as a metal oxide can be useful
due to its availability, economic and environment factors, but its use in the application of
energy storage and devices is very limited. In this thesis, we have Nitrogen-doped Nb2O5
(N-doped Nb2O5) which is synthesized through solid combustion and sol–gel method and
their application in terms of supercapacitive performance are measured
Proper doping of nitrogen doped Nb2O5 into activated carbon enhances its super
capacitive properties. Nitrogen doping shows very interesting and encouraging results but
it has not been studied by many researchers. However, detail study with varying percent
doping has to be explored. Hence, in the present work, the nitrogen doped Nb2O5 will be
synthesized and characterized with different techniques for its phase purity and electrical
properties. Further, the electrochemical / super capacitive performance will be
demonstrated with respect to N doping in Nb2O5. After that material characterization
(SEM/XRD//Edax etc.) and device characterization (CV/impedance/cyclic stability etc.) will
be performed to check the properties and performance of synthesized material and
fabricated supercapacitor.
