Abstracts

The target of this study is in development of "capacity-variable type electric double layer capacitor (EDLC)". Above mentioned capacity-variable system will be attained by use of flow system of the electrolyte which contains vanadium redox couples. We have investigated the electrochemical performance of such EDLC by use of charge discharge curves. As the results the addition of pseudo capacity attributed to vanadium redox couples has been clearly observed. On the other hand the effect of solution flow was investigated.
