Biocompatible and electrolyte embossed wearable textile based supercapacitors from chitosan derived bio-ternary composites crafted fabric electrodes

A typical biocompatible and electrolyte inscribed textile based supercapacitor approached for wearable smart devices. The flexible electrolyte imprinted textile based supercapacitors designed from Chitosan/MnO2@MnCO3 chelate decorated fabrics. The active materials fabricated under BMIMBF4 ionic liquid assistance through hydrothermal method. The physiochemical properties, surface morphological notes are inspected by examining out X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy investigations. The XPS outlines of the composite disclose typical peaks of Mn-2p1/2 (653.4 eV), Mn-2p3/2 (641.5 eV), N-1s (401.2 eV), and C-1s (285.5 eV). The flexible supercapacitor exhibits notable areal capacitance of 2.5 Fcm(-2) and 0.35 Wh cm(-2) energy density. The fabric supercapacitors perform decent capacity retention around 90-89 % after 10,000 chargedischarge cycles with good mechanical flexibility performance. Moreover the obtained biocompatibility results are good to recommend for wearable devices (similar to 90 % cell viability). The chitosan bio-ternary composite crafted textile based supercapacitor may newcomer for the suitability to wearable textile based energy storage system.
