Özet:

 


In the present study, Mn3O4 doped electrodes were
synthesized to improve the cathode V (IV)/V (V) redox reaction of all vanadium
flow batteries. Cathode electrocatalysts were produced with a two-step
hydrothermal method. The crystal structure of the Mn3O4
doped composites and electrodes were analyzed by X-ray diffraction (XRD) and
scanning electron microscopy (SEM) was used for morphological examination of
the samples. Surface modification of the electrodes was confirmed by thermo
gravimetric analysis (TGA) and functional groups on the electrode surface were
determined by X-ray Photoelectron Spectroscopy (XPS). Electrochemical
measurements of the electrodes were conducted with cyclic voltammetry (CV)
technique. Mn3O4 directly loaded onto graphite felt and
carbon paper and Mn3O4/Vulcan XC-72 nanocomposite
increased the electrochemical catalytic activity of cathode V (IV) / V (V)
redox reaction. Peak currents of Mn3O4/Vulcan XC-72 doped
graphite felt and SGL 10AA electrodes are measured as 42.30 and 7.9 mA,
respectively. Despite the low electrical conductivity of Mn3O4,
the composites formed with Vulcan XC-72 improved vanadium flow battery cathode
performance.
