Wire-shaped hybrid supercapacitors have potential for flexible wearable applications due to their durability under the various deformation conditions, ease of manufacturing processes, fast charge/discharge rates, and long cycle life. A wire-shaped hybrid supercapacitor based on three-dimensional (3D) nickel cobalt layered double hydroxide (NiCo LDH) with large electrochemical active sites and improved chemical and structural stability was fabricated for a high-performance supercapacitor with an outstanding energy density. The calculated gravimetric, volumetric, areal, and length capacitance of the 3D-NiCo LDH/Ni nanostructured electrode are 2446 F g-1, 73 F cm-3, 1.04 F cm-2, and 0.18 F cm-1, respectively. When tested in an asymmetric two-electrode system, the 3D- NiCo-LDH@Ni//3D-Mn3O4@Ni wire hybrid supercapacitor exhibited energy density of 153.3 Wh/kg and power density of 8810 kW/kg. The results verified that such wire band-like hybrid supercapacitors are promising for smart wearable and implantable devices.
