Stretchable Fiber Supercapacitors with High Volumetric Performance Based on Buckled MnO2/Oxidized Carbon Nanotube Fiber Electrodes

A stretchable fiber supercapacitor (SC) based on buckled MnO2/oxidized carbon nanotube (CNT) fiber electrode is fabricated by a simple prestraining‐then‐buckling method. The prepared stretchable fiber SC has a specific volumetric capacitance up to 409.4 F cm−3, which is 33 times that of the pristine...

Zusammenfassung:A stretchable fiber supercapacitor (SC) based on buckled MnO2/oxidized carbon nanotube (CNT) fiber electrode is fabricated by a simple prestraining‐then‐buckling method. The prepared stretchable fiber SC has a specific volumetric capacitance up to 409.4 F cm−3, which is 33 times that of the pristine CNT fiber based SC, and shows the outstanding stability and repeatability in performance as a stretchable SC.
