“…A 3D porous metallic substrate not only increases the electron transport kinetics but also provides more porosity, which in turn offers more active sites for ion accessibility. Similarly, as a simple and cost-effective technique, the electrodeposition method is known as a feasible way to deposit metals or metal alloys on conductive substrates. − The vertical growth of electroactive materials on conductive substrates offers plenty of active sites with reduced ion diffusion distance and effective transport of electrons between substrate and electroactive material.…”

Preparation of electrode materials with rich redox peaks, fast ion-passage channels, and excellent cycling stability through a cost-effective process is vitally important for supercapacitors (SCs). In this work, we successfully fabricated a bimetallic selenide NiFe2Se4 through a simple and low-cost electrodeposition method. The resulting NiFe2Se4 electrode prepared at an optimized condition delivers a high specific capacity (372.2 mAh g–1 at 1 A g–1) and desirable cycling stability. Besides, the assembled NiFe2Se4//AC asymmetric supercapacitor (ASC) achieves a high operating voltage (1.6 V) with a maximum energy density of 45.6 Wh kg–1 and an outstanding cycling stability (maintains 101.4% of its original capacitance value after 10 000 cycles). Owing to the superior electrochemical performance, the NiFe2Se4//AC ASCs can light up a red light-emitting diode (LED) for real-time application.

“…It is worth noting that the NiCo 2 S 4 @NiCu−LDH electrode exhibits a high areal capacity of 632.0 μAh/cm 2 (348.0 mAh/g in specific capacity) at a current density of 2 mA/cm 2 , which is about 10.7 times that of the NiCo 2 S 4 (58.9 μAh/cm 2 ) and 5.3 times that of NiCu−LDH (120.0 μAh/cm 2 ) at the same current density. Notably, this result is outperforming many previously reported values for LDH-based nanostructures on carbon cloth, such as NiCo 2 O 4 @NiMn− LDH (278.0 mAh/g at 2 mA/cm 2 ), 23 CoMoO 4 @NiCo−LDH (281.1 mAh/g at 1 A/g), 32 NiCu−LDH (271.3 mAh/g at 0.5 A/g), 34 NiCu-Se@NiCu−LDH (158.9 mAh/g at 1 A/g), 53 NiCoP@NiCo−LDH (270.9 mAh/g at 1 mA/cm 2 ), 54 and NiCo 2 O 4 @NiFe LDH (128.9 mAh/g at 1 A/g). 55 Moreover, even at a high current density of 20 mA/cm 2 , the NiCo 2 S 4 @ NiCu−LDH still possesses an areal capacity as high as 534.0 μAh/cm 2 , corresponding to an exceptional capacity retention of 84.5%.…”

Nickel-based layered hydroxides (LDHs) have aroused much interest as promising battery-type electrodes for hybrid supercapacitors (HSCs) because of their high theoretical capacity, good safety, and abundant natural resources; however, the electrochemical performances are still notoriously limited owing to their intrinsically poor electrical conductivity and severe agglomeration features. Herein, an elaborate hierarchical NiCo 2 S 4 @NiCu−LDH nanotube/nanosheet hybrid electrode is designed and fabricated directly on carbon cloth by a facile multistep solution-based strategy. Through the rational engineering of nanostructures and atomic substitution of nickel by copper, the optimized NiCo 2 S 4 @NiCu−LDH hybrid electrode can yield a high areal capacity of 632.0 μAh/cm 2 at a current density of 2 mA/cm 2 and a good rate capability. Furthermore, the assembled flexible solid-state HSC device employing the NiCo 2 S 4 @NiCu−LDH exhibits a maximum volumetric energy density of 2.7 mWh/cm 3 at a power density of 21.3 mW/cm 3 with a robust long-term cycling stability over 2000 cycles and outstanding flexibility under repeated bending tests. Our work demonstrates the possibility of designing and fabricating nickel-based LDHs as superior battery-type electrodes towards highly durable and efficient flexible energy storage devices.

Recently, transition metal/metal oxides (TMMOs) decorated on porous carbons (PCs) have been intensively focused on designing rational electrode materials for the promising future specific category of electrochemical energy storage and conversion technologies. In particular, TMMO incorporation with PC structures has become very attractive in the area of supercapacitors (SCs) mainly caused by their large accessible surface areas (SSA), together with the suitable pore size distributions (PSD), high electrical conductivity, and rapid redox reactions reversibly on the surface. The transportation of ions, as well as electrons in the bulk of electrodes, is fast as a result of optimal contact between electrodes and electrolytes at the electrode–electrolyte interface, thereby generating high specific capacities (C sp) of these PCs with TMMOs. We report a survey regarding recent advances in the fabrication and synthesis of TMMOs decorated on PCs with some physical characteristics and their applications for electrochemical capacitors. Some future trends and prospects for further development of the subject nanocomposites in application to next-generation supercapacitors are discussed.
