“…At 2 A/g, the specific capacitance of this material reached 730 C/g. Thulasi-Varma ( Thulasi-Varma et al, 2020 ) reported the use of chemical bath deposition to vertically grow chalcogenide nickel compounds (oxygen, sulfur, selenium) above the foamed nickel skeleton layer ( Figure 11 ). After comparing the electrical properties of the compounds, it could be determined that the nickel selenide nanomaterials have far better electrochemical properties than nickel sulfide and nickel oxide, and have a capacitance of 2,234.84 F/g at a current density of 10 mA/cm 2 .…”

Supercapacitors (SCs) have attracted many attentions and already became part of some high-power derived devices such as Tesla’s electric cars because of their higher power density. Among all types of electrical energy storage devices, battery-supercapacitors are the most promising for superior performance characteristics, including short charging time, high power density, safety, easy fabrication procedures, and long operational life. An SC usually consists of two foremost components, namely electrode materials, and electrolyte. The selection of appropriate electrode materials with rational nanostructured designs have resulted in improved electrochemical properties for high performance and has reduced the cost of SCs. In this review, we mainly spotlight the nickel-based selenides nanostructured which applied as high-performance cathode materials for SCs. Different nickel-based selenides materials are highlighted in various categories, such as nickel-cobalt-based bimetallic chalcogenides and nickel-M based selenides. Also, we mentioned material modification for this material type. Finally, the designing strategy and future improvements on nickel-based selenides materials for the application of SCs are also discussed.

“…An improved supercapacitor performance was achieved from selenium vacancy rich nickel selenide nanoplatelets supported on nickel foam prepared through anion exchange reaction between NiO and SeO 2 . [33] However, the above works report the growth of nickel selenide onto nickel substrate which may led to the overestimation of the specific capacity of the electrode material as nickel foam also contributes to the faradaic process. Thus, our objective is to develop a facile synthetic method for the preparation of nickel selenide nanostructures and evaluate their supercapacitor performance by loading them onto the Faradically inert carbon fiber paper.…”

Battery-type supercapacitors have drawn significant attention due to their high charge storage ability resulted from the combined surface and intercalation redox phenomenon. In this regard, nickel chalcogenides are expected to deliver high specific capacity accompanied by their dominant battery-type supercapacitor features. Herein, we have developed a facile one step solvothermal route to prepare pure phase Ni 3 Se 4 nanostructures and attempted to understand the synthetic factors such as solvent and Ni/Se ratio on the formation of Ni 3 Se 4 phase. The obtained Ni 3 Se 4 nanostructures were subjected to the supercapacitor performance evaluation by loading them onto carbon paper and found that the electrode materials are able to store the charge through dominant intercalation redox process (battery-type storage mechanism). Among them, Ni 3 Se 4 (NS-15E(1)) synthesized in water/ethanol (2 : 3) mixture with Ni/ Se (1 : 1) ratio has displayed a high specific capacity of 376 C g À 1 (104 mA hg À 1 ) at a current density of 1 A g À 1 in 2 m KOH. The superior charge storage of NS-15E(1) could be attributed to the improved redox process facilitated by the easier diffusion of electrolyte ions into the bulk of the material. Furthermore, a hybrid device fabricated by using Activated charcoal (AC) and NS-15E(1) as negative and positive electrodes, respectively has showed an extended voltage window of 1.6 V and achieved a high energy density ~20 Wh Kg À 1 at a power density of 329 W kg À 1 .

“…ASCs especially usually combine advantages of the two different types of electrodes, which can provide a high capacitance and a long cycle life [ 4 ]. As a main component of SCs, various electro-active materials have been explored, such as carbonaceous materials (carbon nanotubes [ 5 , 6 , 7 ] (CNTs), graphene [ 8 , 9 ] and active carbon [ 10 ]), transition metal-based materials (RuO 2 [ 11 ], MnO 2 [ 12 ], NiO [ 13 ], Co 3 O 4 [ 14 ]), sulfides [ 15 ], metal selenides [ 16 ] and conducting polymers (PANI [ 17 ], PPy [ 18 ], PEDOT [ 19 ]).…”

Electrode materials are key factors for supercapacitors to endow them with excellent electrochemical properties. Here, a novel hybrid structure of a CoSe/Co3O4-CNTs binder free composite electrode on nickel foam was prepared via a facile flame method, followed by an electrodeposition process. Benefitting from the synergetic effects of the multicomponent (with low resistances of 1.542 Ω cm2 and a moderate mesoporous size of 3.12 nm) and the enlarged specific surface area of the composite material (77.4 m2 g−1), the CoSe/Co3O4-CNTs composite electrode delivers a high specific capacitance of 2906 F g−1 at 5 mV s−1 with an excellent rate stability. The fabricated CoSe/Co3O4-CNTs/NF//AC ASC exhibits a high energy density of 43.4 Wh kg−1 at 0.8 kW kg−1 and a long cycle life (92.7% capacitance retention after 10,000 cycles).
