“…After mass balancing, the estimated mass loading ratio of positive to negative electrodes is optimized to be 0.282. Such high potential window of this solid-state FHSC is also wider/comparable to the previous reports based on wire/fiber-type hybrid SCs, such as Ni 3 S 2 /Ni // pen ink-based wire-type SC (1.4 V), [20] fiber-based β-Co(OH) 2 // CoFe 2 O 4 @rGO@PANI solid-state SC (1.5 V), [11a] and fiber-based Co 3 O 4 //graphene SC (1.5 V), [21] respectively. To avoid the absorbing moisture and contact of gel electrolyte with human skin, the device was inserted into the heat shrinkable plastic pipe.…”

In recent years, electronic waste (e‐waste) such as old cable wires, fans, circuit boards, etc., can be often seen in large piles of leftover in dumping yards. Employing these e‐waste sources for energy storage devices not only increases the economic value but also decreases the reliance on fossil fuels. In this context, waste cable wires are utilized to obtain precious copper (Cu) fibers and used as a cost‐effective current collector for the fabrication of fiber‐based hybrid supercapacitor (FHSC). With the braided Cu fibers, forest‐like nickel oxide nanosheet grafted carbon nanotube coupled copper oxide nanowire arrays (NiO NSs@CNTs@CuO NWAs/Cu fibers) are designed via simple wet‐chemical approaches. As a battery‐type material, the forest‐like NiO NSs@CNTs@CuO NWAs/Cu fiber electrode shows superior electrochemical properties including high specific capacity (230.48 mA h g−1) and cycling stability (82.72%) in aqueous alkaline electrolyte. Moreover, a solid‐state FHSC is also fabricated using forest‐like NiO NSs@CNTs@CuO NWAs/Cu fibers as a positive electrode and activated carbon coated carbon fibers as a negative electrode with a gel electrolyte, which also shows a higher energy and power densities of 26.32 W h kg−1 and 1218.33 W kg−1, respectively. The flexible FHSC is further employed as an energy source for various electronic gadgets, demonstrating its suitability for wearable applications.

“…The AC//Ni 3 C delivers a high energy density of 37 Wh/kg at 0.3995 kW/kg to 18.4 Wh/kg at 0.96 kW/kg. It is also higher than that of other Nickel-compounds-based ASCs that have been reported in recent years [28][29][30][31][32][33] . Volumetric energy density vs. power density is shown in Fig.…”

“…Encouragingly, the NF@rGO/Ag/Ni 3 S 2 //N‐G ASC delivers a high energy density of 28.7 W h kg −1 at a power density of 425 W kg −1 with the voltage window of 1.7 V, and still maintains at 20.2 W h kg −1 at a power density of 6799.3 W kg −1 . This impressive results are much higher than those of similar SCs reported recently, such as Ni 3 S 2 //pen ink (8.2 W h kg −1 at 214.6 W kg −1 ), ppy@Ni 3 S 2 //AC (17.5 W h kg −1 at 179.3 W kg −1 and 8.7 W h kg −1 at 3587.4 W kg −1 ), Ni 3 S 2 @CoS//AC (23.7 W h kg −1 at 268.9 W kg −1 ), Ni 3 S 2 /MWCNT‐NC//AC (19.8 W h kg −1 at 798 W kg −1 ), Ni 3 S 2 //AC (36 W h kg −1 at 400 W kg −1 and 20.6 W h kg −1 at 2390 W kg −1 ) …”

A facile and cost‐effective route is developed for synthesizing 3D bush structure of Ag nanoparticles‐decorated Ni3S2 grown on reduced graphene oxide (rGO) for the first time. In this composite, Ni3S2 exhibits nanosheet networks with porous feature. The electrochemical measurements display that the as‐prepared rGO/Ag/Ni3S2 composite possesses a superior areal capacitance of 5920 mF cm−2 at current density of 5 mA cm−2. 77.5% of the initial areal capacitance is retained as current density increased from 5 to 20 mA cm−2. Encouragingly, this electrode exhibits excellent cycle performance with 94% capacitance retention after 3000 cycles at a current density of 30 mA cm−2, whereas for rGO/Ni3S2 composite electrode, only 84.7% of the initial value is maintained. The enhanced conductivity and unique structure of rGO/Ag/Ni3S2 composite attribute to its superior electrochemical performance. In addition, an aqueous asymmetric supercapacitor is fabricated using rGO/Ag/Ni3S2 composite as positive electrode and the nitrogen‐doped graphene as negative electrode. The assembled device delivers high energy density of 28.7 Wh kg−1 at a power density of 425 W kg−1. This work may prompt the development and application of active materials decorated with highly conductive nanoparticles in supercapacitors.
