Improved Polymer Membrane for Textile Zinc-Ion Capacitor

Year: 2025

Type: article

Abstract: This work presents the design, fabrication and characterisation of an improved textile energy storage device implemented in a single layer of polyester cotton and silk fabric. To achieve this, the energy storage device has evolved from an electrical double-layer (EDL) supercapacitor to a zinc-ion supercapacitor (ZHSC) with an optimised co-polymer membrane containing a polyethene oxide (PEO) additive and a polyvinylidene (PVDF)-based organic electrolyte. The flexible textile ZHSC achieved an areal capacitance of 159.5 mF cm−2 and an energy density of 52.3 µWh cm−2 (increasing by a factor of 4 and 1.8, respectively, on the previous work) with a power density of 0.27 mW cm−2 and good bending stability.
