Recent advances of spinel CuCo2O4 in different Structural dimensions (0D-3D) for an electrochemical supercapacitor device: a short research review

An electrochemical supercapacitor device that assumes a significant part in gathering sustainable electrical energy to satisfy the need for worldwide energy utilization. The electrode is one of the fundamental parts of a supercapacitor device, sometimes a single material is deficient in satisfying the electrode material requirement. Hence, the researcher’s key challenge is to produce the Binary/Ternary/Quaternary materials and utilize them to fabricate the electrode with a large surface area, novel shape, and controlled dimensions. In this short review, we outline current developments in the design of nanostructured spinel-based CuCo₂O₄ electrodes in different Structural dimensions such as zero-, one-, two-, and three-dimensions for the application of supercapacitors. The surface area, charge transport efficiency, and overall electrochemical performance of the supercapacitor are all significantly influenced by the dimensionality of the electrode materials. Supercapacitors can have much higher energy and power densities by designing and using materials with the right dimensions. It has been specifically explained how various dimensional architectures relate to the appropriate electrochemical performances, including specific capacitance, rate capability, cycle stability, power density, and energy density, which may serve as a guideline for the next generation of supercapacitor electrode design.
