文摘

Novel coral-structured MnO2 on carbon fiber fabric (CFF) was first time fabricated. Solid-state highly flexible CFF/MnO2 based supercapacitor device is fabricated. The device exhibits an outstanding specific capacitance of 467 F/g. The device displays outstanding capacitance retention of 99.7% after 5000 cycles. Coulombic efficiency close to 100% is achieved for device with high energy density.
