TLDR
A coaxial electric double-layer capacitor fiber is developed from the aligned carbon nanotube fiber and sheet, which functions as two electrodes with a polymer gel sandwiched between them.Abstract:
A coaxial electric double-layer capacitor fiber is developed from the aligned carbon nanotube fiber and sheet, which functions as two electrodes with a polymer gel sandwiched between them. The unique coaxial structure enables a rapid transportation of ions between the two electrodes with a high electrochemical performance. These energy storage fibers are also flexible and stretchable, and can be woven into and widely used for electronic textiles.read more

Multi-layer unbonded nickel foam/carbon nanotube array/Ni-Co bimetallic sulfide as high-performance electrode materials for supercapacitors
TL;DR: In this article, the authors applied the idea of layered preparation, using nickel foam as the prepared substrate, carbon nanotubes as the structural stabilizer, and using the pseudocapacity performance advantage of Ni-Co bimetallic sulfide to prepare multistage NF/CNTs/Ni-Co-S composite electrode materials step by step.

Carbon properties and their role in supercapacitors
TL;DR: Supercapacitors are able to store and deliver energy at relatively high rates (beyond those accessible with batteries) because the mechanism of energy storage is simple charge-separation (as in conventional capacitors) as discussed by the authors.
