dc.description.abstract | The supercapacitive charging/discharging (C/DC) response of lanthanum-based perovskite oxides,
obtained by ultrasonic spray pyrolysis (USP), was discussed according to galvanostatic and the
dynamic ac impedance C/DC data. We have synthesized perovskite type lanthanum strontium cobalt
oxide (LSCO, La0.6Sr0.4CoO3) by USP and mixed LSCO/RuO2 by subsequent hydrothermal
impregnation method. The obtained composites were investigated as electrode for electrochemical
supercapacitors and their electrochemical performances have been investigated. Microstructures
and surface morphologies, observed by scanning electron microscopy, appears crystalline with
spherically-shaped nm-sized particles. The aim of our work was study of structural and
electrochemical properties of ternary perovskite and LSCO/RuO2 as a supecapacitive material of
improved stability with respect to carbonaceous ones. Potentiostatic ac impedance analysis has
indicated lower charge transfer resistance of the LSCO/RuO2 sample confirming its enhanced
electrochemical performances. The measurements indicated that nanocomposite LSCO/RuO2 is more
suitable catalytic material with improved electrochemical performances. | en |
