Abstract

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 based materials 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.

Highlights

Today’s “wearable technologies” mostly consist of electronic devices like wrist bands for fitness and health monitoring
As the excellent electrode materials, carbon nanotube can be widely used as compatible electrochemical active materials, as well as the carrier or substrate integrated in wearable energy storage devices
We subsequently focus on the potential applications of the fibers in energy storage system, and elaborately discuss how to combine the prepared fibers with nanostructured active materials with different compositing approaches to intrinsically enhance their capacitive performances
