Electrochemically constructing V-doped BiFeO3 nanoflake network anodes for flexible asymmetric micro-supercapacitors

Bismuth ferrite (BiFeO3) with high specific capacity and wide voltage window, fundamentally stores charge through the reversible redox reactions of cations, but usually suffers from poor rate capability and bad cycling stability, due to its densely-packed crystal structure and multi-electron redox reaction kinetics. We present a novel route to regulate nanoflake network architectures and oxygen vacancy defects of BiFeO3 through V doping and...
