ABSTRACT

The collection of one-dimensional inorganic nanomaterials is intended to render collective contributions, which reports the recent progress in this sector. In order to meet the demand in the field of energy-storing devices, a different perspective with a new approach is needed in the power sources sector. Construction of supercapacitors with new design of materials for the integral parts will extend the boundaries and will replace the existing ones. Enhancement in the electrochemical performance of the components of supercapacitors and their consistency can certainly satisfy the demands. Greater mechanical strength, effective transportation of electrons, and higher specific area are some of the significant characteristics of these specified inorganic one-dimensional nanostructure materials which make them interesting and inevitable. These versatile attributes allow designing the adaptable supercapacitors with greater features. Excellent retention efficiency, higher-level energy density, power density of superior grade, and greater specific capacitance are some of the noble desired properties of one-dimensional nanomaterials which enable to fabricate the components of demanding supercapacitors. Nanotubes, nanorods, nanoneedles, nanosponges, nanoarrays, and nanoribbons are a few different structures of one-dimensional nanomaterials, employed as electrode components for making various types of supercapacitors such as double-layer capacitor and hybrid capacitor. The active-transition metal oxides, such as CoO, Co3O4–MnO2–NiO, La1− x Sr x MnO3, MnO2, MoO2, MoO3, Mn3O4, MnCo2O4.5, NiO, NiV2O6, NiCo2S4, NiCo2O4, VO2/TiO2, V2O5, Y2NiMnO6, ZnO, ZnO/Co3O4, and ZnCo2O4, their roles in nano-forms in terms of their desirable features for superconductors such as high specific capacitance and rapid and greater reversible faradic reactions are noted. The allotropies of carbon such as graphene and their roles in the fabrication of one-dimensional materials are also discussed. Energy-storing electronic devices of the forthcoming generation would be prepared by using one-dimensional nanostructured materials. Herein, the current status of various one-dimensional nanostructured materials used in supercapacitors and their present challenges and prospects are described.
