Recent Advances in Metal Oxide/Hydroxide on 3D Nickel Foam Substrate for High Performance Pseudocapacitive Electrodes

Abstract The high demand for long-lasting and portable energy storage devices with enhanced energy and power densities has attracted researcher’s interest globally. The 3D nickel foam is a promising electrode material for storing energy in various devices because they possess large surface area, are very conductive and enjoy a continuous permeable 3D system. This article provides a review and detailed information on the uses of 3D nickel foam-based electrodes with metal oxides/hydroxides of different morphologies for high-performance pseudocapacitors. We assess the limitations and future prospects of 3D nickel foam-based electrodes with metal oxides/hydroxides for industrial application towards enhancing pseudocapacitors' energy storage capability.
