Unique MnO2 nanoflowers (∼25 nm) composed of ultrathin K0.26MnO2 nanoflake assemblies were synthesized by a facile and green procedure. Prototype MnO2-NFs//KCl//CNTs asymmetric supercapacitors in a neutral aqueous electrolyte demonstrated pseudocapacitive dominance for the first time in addition to outstanding energy and power densities and superior cycling performance.
