Hierarchical Nanosheets/Walls Structured Carbon‐Coated Porous Vanadium Nitride Anodes Enable Wide‐Voltage‐Window Aqueous Asymmetric Supercapacitors with High Energy Density

Abstract The energy density of aqueous asymmetric supercapacitors (ASCs) is usually limited by low potential windows and capacitances of both anode and cathode. Herein, a facile strategy to fabricate hierarchical carbon‐coated porous vanadium nitride nanosheet arrays on vertically aligned carbon wal...
