Wire-shaped hybrid supercapacitors are candidates for flexible wearable applications due to their features of durability under the various deformation conditions, ease of manufacturing, high power delivery ability, fast charge/discharge rates, long cycle life, and low environmental impact. This presentation suggests the novel methods for construction of hybrid supercapacitors with enhanced energy density. A wire-shaped hybrid supercapacitor based on three-dimensional (3D) nickel cobalt layered double hydroxide (NiCo LDH) onto the three-dimensional nickel wire (3D-Ni) with short electron path distances, large electrochemical active sites, and improved structural stability was fabricated as a binder/conductive additive-free electrode for a high-performance supercapacitor. All-solid-state asymmetric supercapacitor achieves a high cell voltage of 1.8V and an exceptional energy density of 153.3 Wh/kg at a power density of 8810 W/kg. Further, the feasibility of the as-fabricated hybrid device was tested in real time conditions by driving LED lights, LCD smart devices, a thermometer, and a wearable watch. The results verified that such wire band-like hybrid supercapacitors are promising for smart wearable and implantable devices having energy delivering capacity and flexibility and might be attractive substitutes for batteries.
