Towards High-Power Printed Textile Supercapacitors igh

Abstract

The mass commercialization of electronic textiles is currently hindered due to the lack of reliable manufacturing technologies of energy storing textiles. To incorporate energy storage as a part of a garment, it must be manufactured in a systematic manner, allowing the integration of multiple components of electronic textiles simultaneously. Aiming towards process automation, carbon-based screen-printing inks were formulated for textile supercapacitor applications, focusing on the effect of carbon additives in the electrochemical performance. Devices were assembled, and their electrochemical performance was assessed. The maximum areal power density obtained was 12 mW cm−2 with an areal energy density of 1.08 × 10−3 mWh cm−2.
