چکیده

The prevention of environmental damage in durable unsymmetrical huge-capacitor (UHC) with α-MnO₂ nanotubes and amorphous Fe₂O₃ nanotubes grown on flexible carbon fabric is first designed and fabricated. The assembled novel flexible UHC device with an extended operating voltage window of 1.6 V exhibits excellent performance such as a high energy density of 0.55 mWh/cm³ and good rate capability. The UHC devices can find numerous applications as effective power sources, such as powering color-switchable sun glasses and smart windows.
