Activated carbon fibers with manganese dioxide coating for flexible fiber supercapacitors with high capacitive performance

论文摘要

Fiber supercapacitor（FSC）is a promising power source for wearable/stretchable electronics and high capacitive performance of FSCs is highly desirable for practice flexible applications.Here,we report a composite of manganese dioxide（Mn O2）and activated carbon fibers（ACFs）with high MnO2mass loading and microporous structure（abbreviated as Mn O2@ACF）,which is used as a fiber electrode to produce a FSC with a high capacitive performance and a good flexibility.The MnO2@ACF composite electrode in FSCs delivers an ultrahigh specific capacitance of 410 mF/cm2at 0.1 mA/cm2,corresponding to a high energy density of 36μWh/cm2and high power density of 726μW/cm2.Such high capacitive performance and simple fabrication method indicates that the Mn O2@ACF composite is a very promising electrode material for flexible fiber supercapacitors.
