Synergistic engineering of fluorine doping and oxygen vacancies towards high-energy and long-lifespan flexible solid-state asymmetric supercapacitor
The low electron conductivity and scarce electrochemically active sites impede the practical application of bimetal oxides for supercapacitors. Herein, fluorine-doped and oxygen vacancy–enrich NiMoO 4 (F-NiMoO 4-x ) nanosheet arrays are constructed via facile hydrothermal and wet chemical reduction...
