Perovskite SrCo0.9Nb0.1O3−δ as an Anion-Intercalated Electrode Material for Supercapacitors with Ultrahigh Volumetric Energy Density

© 2016 WILEY-VCH Verlag GmbH & Co. KGaA, WeinheimWe have synthesized and characterized perovskite-type SrCo0.9Nb0.1O3-d(SCN) as a novel anion-intercalated electrode material for supercapacitors in an aqueous KOH electrolyte, demonstrating a very high volumetric capacitance of about 2034.6 F cm-3...

When coupled with an activated carbon (AC) electrode, the SCN/AC asymmetric supercapacitor delivered a specific energy density as high as 37.6 Wh kg-1with robust long-term stability. 2016 Journal Article http://hdl.handle.net/20.500.11937/38247 10.1002/anie.201603601 Wiley-VCH Verlag restricted
