MIL-53(Fe)-Derived Oxygen Vacancy-Regulated Iron Oxides Cathode Enabling Long-Cycling Flexible Iron-Ion Hybrid Supercapacitors.
The practical application of iron-ion hybrid capacitors is severely hindered by inadequate energy density and insufficient cycling robustness. Herein, we present a self-supporting electrode comprising iron-based oxide/carbon composites, fabricated via in situ pyrolysis of MIL-53(Fe) precursors directly on carbon cloth....
