- Abstract
- We report novel and simple structure of supercapacitors fabricated by using flexibleglass fibre separators as templates. This method does not require separate electrodes, bindersand high pressure/temperature to build the supercapacitor unit cells as required by the conventionaltechnology. The supercapacitors were fabricated by drop-casting solution mixtures of carbonaceousactive materials/gel electrolytes onto two sides of glass fibre separators. Twocarbonaceous materials (nanoscaled activated carbons, multi-walled carbon nanotubes) wereinvestigated as electrode materials. The electrochemical measurements reveal that the separatorbasedsupercapacitors using ACs successfully demonstrated significant mass specific capacitance(22.3 F g−1) and energy density (9.7Wh kg−1), indicating this method can be useful in fabricatingflexible, wearable and stretchable energy storage devices in more straightforward andcost-effective way than current technology.
