Flexible Textile Zinc Ion Supercapacitor

Abstract

This work presents the design, fabrication and characterization of a flexible zinc ion supercapacitor (ZIC) implemented in a single layer of polyester cotton textile. The carbon cathode and zinc anode of the ZIC were fabricated on polyester cotton textile in which a polymer separator membrane has been fabricated. The flexible encapsulated ZIC achieved an area capacitance of 33mF·cm- ² , an energy density of 8.5 μWh·cm-2 and a power density of 1.22 mW·cm- ² and good bending stability.
