“…Several methodologies have been employed for the synthesis of supercapacitor electrode materials. The most frequently used methods are electrochemical deposition techniques, [46,80,81] solvothermal/hydrothermal methods, [82–84] chemical precipitation method, [85–87] sol‐gel method, [51,88] chemical vapor deposition, [52,53,89] and chemical bath deposition [90] . However, electrochemical deposition techniques are considered the most useful for preparing supercapacitor electrode materials.…”

The demand for energy storage devices with high energy and power densities has increased tremendously in this rapidly growing world. Conventional capacitors, fuel cells, and lithium‐ion batteries have been used as energy storage devices for the long term. However, supercapacitors are one of the most promising energy storage devices because of their high specific capacitance, high power density, and longer cycle life. Recent research has focused on synthesizing transition‐metal oxides/hydroxides, carbon materials, and conducting polymers as supercapacitor electrode materials. The performance of supercapacitors can be improved by altering electrolytes, electrode materials, current collectors, experimental temperatures, and film thickness. Thousands of papers on supercapacitors have already been published, reflecting the significance and elucidating how much demanding such energy storage devices for this fast‐growing generation. This review aims to illustrate the electrode materials loaded on various conductive substrates by electrochemical deposition employed for supercapacitors to provide broad knowledge on synthetic pathways, which will pave the way for future research. We also discussed the basic parameters involved in supercapacitor studies and the advantages of the electrochemical deposition techniques through literature analysis. Finally, future trends and directions on exploring metals/metal composites toward designing and constructing viable, high‐class, and even newly featured flexible energy storage materials, electrodes, and systems are presented.

Heterostructure construction and heteroatom modification are considered as effective approaches to modulate the electronic structure and boost the energy storage activity of electrode materials. Herein, oxygen-modified CuS/Mn 3 O 4 (O-CuS/Mn 3 O 4 ) heterogeneous nanoflakes with abundant defects are fabricated by solid-state grinding followed by NaBH 4 treatment (NBHT) at room temperature using MnCu Prussian blue analogue (MnCu-PBA) as the precursor. During the NBHT, a portion of the sulfur atoms in CuS is removed, and the remaining sites in the lattice are occupied by oxygen in the water, resulting in an oxygen modification. Experimental results and theoretical calculations confirm that heterojunction, defect, and oxygen modification not only greatly facilitate the adsorption of OH − on the surface of the electrode material but also endow improved electrical conductivity, wettability, specific surface area, and active sites. Benefiting from these advantages, O-CuS/Mn 3 O 4 exhibits an excellent specific capacitance of 1307 F g −1 at 1 A g −1 . Moreover, the solid-state asymmetric supercapacitor with O-CuS/Mn 3 O 4 and MnO 2 (O-CuS/Mn 3 O 4 //MnO 2 ) shows an outstanding energy density of 34.4 Wh kg −1 at 800.1 W•kg −1 and cyclic stability with 85.7% capacitance retention after 5000 cycles at 6 A g −1 . Our work highlights the integration of heterojunction and oxygen modification to fabricate and optimize the energy storage electrode materials.
