Abstract Scope We demonstrate rational design and fabrication of energy storage devices from cotton textiles. We further unveiled that the electrochemical properties of nanostructured activated carbon textiles (ACTs) are morphology-dependent. The specific capacitance increased exponentially with the surface/volume ratio of nanostructures coated on the textiles. The architecture with higher surface area exhibits better electrochemical performance. Flexible ACTs wrapped with conductive graphene were used as negative material. After coated with PVA-KOH polymer gel which served as both the solid state electrolyte and separator, the flexible core/shell CoO@NiO/ACT//ACT/graphene asymmetric cell exhibited an exceptional combination of electrochemical properties. The eminent electrochemical performance is ascribed to the unique core/shell nanostructure with high surface/volume ratio, short ion transport path, and fast charge transport. Such hierarchical nanostructure on cotton-enabled flexible textile substrate should find more applications in next-generation flexible solid-state power sources for future wearable electronics.
