| dc.description.abstract | Double perovskites oxides possess unique properties for energy storage applications due to
their more orderly arrangement of structures than the doped perovskites, thus controlling the
distortion in lattice and thereby increasing cyclic stability. Recently, due to this high energy
demand, La2CoMnO6 perovskite manganite was explored as a suitable electrode material for
high-performance supercapacitors. La2CoMnO6 double perovskite was synthesized via
modified combustion route. XRD with Rietveld refinement confirms monoclinic structure
with space group of P21/n. Irregular shaped porous morphology and elemental analysis were
determined from FE-SEM and EDAX spectra respectively. Existence of mixed valence state
of Co and Mn were verified by XPS spectra and its bandgap was determined using Tauc plot.
Vibrational analysis validates the formation of perovskite phase and degeneracy in Raman
modes/thermal broadening provides signature vibrational bands corresponding to stretching
and bending motions of MnO6 and CoO6. Supercapacitor performance using La2CoMnO6 as
electrode material exhibits 84% of cyclic stability after 500 cycles. This findings confirmed
that La2CoMnO6 manganite can be used for energy storage applications. | en_US |
