바나듐레독스흐름전지용 카본펠트전극의 알칼리용액을 이용한 표면개질 = Surface Treatment with Alkali Solution of Carbon Felt for Vanadium Redox Flow Battery

다국어 초록 (Multilingual Abstract)

The carbon felt used as the electrode of vanadium redox flow battery (VRFB) requires imprived electrochemical activity for better battery performance and efficiencies. Many efforts have been tried to improve electrochemical activity of the carbon felt as electrodes. In this study the alkali solution, KOH, is applied on surface treatment of the carbon felt electrode. The carbon felts were treated with KOH under room temperature and 80°C.
The isopropyl alcohol was applied to improve wettability of the carbon felt during KOH treatment. The KOH treated carbon felt was analyzed by using the X-ray photoelectron spectroscopy (XPS). The XPS analysis of carbon felt electrode revealed on increase in the overall surface oxygen content of the carbon felts after KOH treatment.
Also, cyclic voltametry tests showed electrochemical characteristics enhancement of the carbon felt.
