Abstract
An assembled-graphite/DSA(Dimensionally Stable Anode) was prepared using graphite powder to increase durability and energy efficiency of redox flow battery and investigated its electrochemical properties in vanadium-based electrolyte. The cyclic voltammetry (CV) was carried out in the voltage range of −0.7V and 1.6V vs. SCE at 5mV/sec scan rate to analyze vanadium redox reaction. From the CV results, the assembled-graphite/DSA electrode showed a fast couple reaction and good reversibility in 2M VOSO4 + 2.5 M H2SO4 electrolyte. Therefore, it has been expected that this electrode increases power density as well as energy density of redox flow battery.
