Energy storage is a key requirement for the emerging wearable technologies. Recent
progress in this direction includes the development of fiber based batteries and
capacitors and even some examples of such fibers incorporated into prototype textiles.
Herein we discuss the advantages of using the wet-spinning process to create
nanostructured carbon basedmaterials as wearable energy storage. The ability to control
the physical, mechanical, electrical, and electrochemical properties of carbon nanotube
based fibers holds great promise to develop smart polymeric structure as an energy
storing materials including fibers and textiles. This is the first comprehensive review to
discuss effect of nanostructured energy materials on the electrochemical properties of
carbon nanotube based fibers which covers the various compositions, spinning and
fabrication conditions on the performance of wearable energy storage.
