| 제목 | Charging-discharging performance analysis of vanadium acetylacetonate non-aqueous redox flow battery using Na-β-alumina tubular separator |
| 초록 | It is well documented that the non-aquous electrolytes are stable over wide electrochemical potential windows and therefore possible to make higher energy and power density RFBs. In this regard, the Na-B-alumina tubular saparator can be potentially use in non-aqueous RFBs. In the present investigation, the Na-B-alumina separator performance evaluated using vanadium (III) acetylacetonate in acetonitrile medium. Initial charging-discharging of Na-B-alumina was performed by ptentiostatic mode using three different applied potentials (4.5V, 5.5 V and 6.0 V) with charging and discharging time difference of 30 min and 60 min. A columbic and energy efficiencies were calculated using the charging-discharging data. In separate charging-discharging experiment using Nafion324 membrane was performed and compared the columbic and energy efficiencies. Key words: Na-B-alumina, non-aqueous, RFB, V(III)(acetylacetonate) |
