In‐Plane Assembled Orthorhombic Nb₂O₅ Nanorod Films with High‐Rate Li⁺ Intercalation for High‐Performance Flexible Li‐Ion Capacitors

Organic hybrid supercapacitors that consist of a battery electrode and a capacitive electrode show greatly improved energy density, but their power density is generally limited by the poor rate capability of battery‐type electrodes. In addition, flexible organic hybrid supercapacitors are rarely reported. To address the above issues, herein an in‐plane assembled orthorhombic Nb 2 O 5 nanorod film anode with high‐rate Li + intercalation to...
