This review discusses the structure-property relationship of nickel oxide nanostructures as excellent supercapacitive materials and provides an overview of various preparation methods and strategies to enhance specific capacitance. It comprehensively analyzes the current status, challenges, and future prospects of nickel oxide electrode materials for energy storage devices.
In recent years, Nickel oxide (NiO) nanostructures gained more attention due to their excellent supercapacitive performances. The increasing global needs promote researchers to develop efficient energy storage devices to fulfill the requirements of mankind in an eco-friendly way. NiO-based energy storage devices are habitat-friendly and cost-effective. This review anchors the structure-property relationship of nickel oxide electrode materials, and the enhancement of structural designs to optimize the specific capacitance, and storage mechanism. An overview of various methods of preparation for NiO-based nanostructures is highlighted and discussed in detail. Moreover, various strategies to enhance the specific capacitance, capacitive retention, cyclic stability, energy density, and, power density have been summarized based on the experimental findings along with the incorporation of broadly used in-silico approaches. The present review reveals a concrete overview of the current status, challenges, and future perspective of NiO-based electrode materials for energy storage devices.
