“…The plot of Ni 3 Se 2 produced an oxidation peak at 0.45 V and a corresponding reduction peak at 0.25 V, indicating the typical Faradic behavior of Ni 3 Se 2 . The redox reaction can be logically established as

“…Meanwhile, the potential of Ni 3 Se 2 @Ni(OH) 2 peaks was becoming broader and the oxidation peak current of Ni 3 Se 2 @Ni(OH) 2 notably increased from 0.06 A of Ni 3 Se 2 to 0.125 A as a result of the synergetic effect of Ni 3 Se 2 and Ni(OH) 2 . The redox reactions on the Ni 3 Se 2 @Ni(OH) 2 electrode can be logically established as follows

{Ni}_{normal3} {Se}_{normal2} + {3OH}^{-} \to \leftarrow {Ni}_{normal3} {Se}_{normal2} {(normalOH)}_{normal3} + {3e}^{-}

Ni {(normalOH)}_{normal2} + {OH}^{-} \to \leftarrow NiOOH + {normalH}_{normal2} O + {normale}^{-}

Porous Ni(OH)2 nanoflakes are directly grown on the surface of nickel foam supported Ni3Se2 nanowire arrays using an in situ growth procedure to form 3D Ni3Se2@Ni(OH)2 hybrid material. Owing to good conductivity of Ni3Se2, high specific capacitance of Ni(OH)2 and its unique architecture, the obtained Ni3Se2@Ni(OH)2 exhibits a high specific capacitance of 1689 µAh cm−2 (281.5 mAh g−1) at a discharge current of 3 mA cm−2 and a superior rate capability. Both the high energy density of 59.47 Wh kg−1 at a power density of 100.54 W kg−1 and remarkable cycling stability with only a 16.4% capacity loss after 10 000 cycles are demonstrated in an asymmetric supercapacitor cell comprising Ni3Se2@Ni(OH)2 as a positive electrode and activated carbon as a negative electrode. Furthermore, the cell achieved a high energy density of 50.9 Wh L−1 at a power density of 83.62 W L−1 in combination with an extraordinary coulombic efficiency of 97% and an energy efficiency of 88.36% at 5 mA cm−2 when activated carbon is replaced by metal hydride from a commercial NiMH battery. Excellent electrochemical performance indicates that Ni3Se2@Ni(OH)2 composite can become a promising electrode material for energy storage applications.

“…Compared with traditional devices, supercapacitors are deemed the most likely candidate to meet these demands, due to their fast charge-discharge times, long cycle stability, and outstanding power densities [6][7][8][9][10][11] . The performance of supercapacitors is known to be highly dependent on electrode materials and structures [12][13][14][15][16][17] . Many studies have focused on designing desirable electrodes with prominent energy densities and long cycle stability [18][19][20][21][22] .…”

“…Recently, electrochemical energy storage devices have received much attention due to the increasing population and the sharp depletion of fossil fuels [1][2][3][4]. Supercapacitors (SCs) are a promising green energy storage device because of their high power density, fast charge-discharge rate, long-cycle stability, and eco-friendliness [5][6][7][8][9][10]. These attractive properties have prompted their use in electric vehicles, wearable electronic and medical electronic devices, and military equipment [11][12][13].…”

In this work, solid-state polymer supercapacitor (SSC) was assembled using poly(3,4-ethylenedioxythiophene/carbon paper (PEDOT/CP) as an electrode and ionic liquid (1-butyl-3-methylimidazole tetrafluoroborate)/polyvinyl alcohol/sulfuric acid (IL/PVA/H2SO4) as a gel polymer electrolyte (GPE). The GPE was treated through freezing–thawing (F/T) cycles to improve the electrochemical properties of PEDOT SSC. Cyclic voltammetry (CV), galvanostatic charge–discharge measurements (GCD) and electrochemical impedance spectroscopy (EIS) techniques and conductivity were carried out to study the electrochemical performance. The results showed that the SSC based on ionic liquid GPE (SSC-IL/PVA/H2SO4) has a higher specific capacitance (with the value of 86.81 F/g at 1 mA/cm2) than the SSC-PVA/H2SO4.The number of F/T cycles has a great effect on the electrochemical performance of the device. The energy density of the SSC treated with 3 F/T cycles was significantly improved, reaching 176.90 Wh/kg. Compared with the traditional electrolytes, IL GPE has the advantages of high ionic conductivity, less volatility, non-flammability and wider potential window. Moreover, the IL GPE has excellent elastic recovery and self-healing performance, leading to its great potential applications in flexible or smart energy storage equipment.
