Ni,S co-doped Cu dendrites decorated with core–shell architecture assisted by MOF and Fe 0.92 Co 0.08 S nanoflakes on nanocellulose/graphene fibers for fabrication of flexible wire-type micro-supercapacitor

and outstanding cycling stability in PVA/KOH electrolyte and preserved the capacitive performance under various bending states. This research highlights that assembled 1D micro-SCs have a high potency for next-generation portable/wearable energy-supply microelectronics.
