A facile one-pot hydrothermal synthesis of Co₉S₈/Ni₃S₂ nanoflakes for supercapacitor application

Abstract

Co9S8/Ni3S2 nanoflakes have been successfully designed and constructed on nickel foam substrate via a simple one-pot hydrothermal synthesis and exhibit high performance as supercapacitor.

NiCo2S4@NiMoO4 Core-Shell Heterostructure Nanotube Arrays Grown on Ni Foam as a Binder-Free Electrode Displayed High Electrochemical Performance with High Capacity

“…Lately, numerous attempts have been conducted to develop transition metal sulfides including CoS [18], NiS [19], CuS [20], Co 9 S 8 [21], and NiCo 2 S 4 [22] as supercapacitor electrode materials because of the gratifying electrical conductivity in comparison with the corresponding metal oxides [5]. Moreover, the ternary sulfides also can possess a higher conductivity and offer more richer redox reactions than those bare binary sulfides owing to the combine contributions from both metal ions [23, 24].…”

Facile Construction of 3D Reduced Graphene Oxide Wrapped Ni3S2 Nanoparticles on Ni Foam for High‐Performance Asymmetric Supercapacitor Electrodes

“…Hence, the actual capacitance value of rGO/Ni 3 S 2 composites is higher than the presented value in the paper. The loading mass of rGO/Ni 3 S 2 on NF in this paper was about 5.1 mg cm −2 …”

“…In general, carbon materials, transition metal oxides, and conductive polymers are the typical electrode materials, which have been widely studied in previous reports . Among various electrode materials, Ni 3 S 2 is an especially attractive candidate for SCs for its high theoretical specific capacitance, low cost, and environmentally friendly nature . However, this type of electrode material usually suffers from poor electrical conductivity, serious aggregation, and unstable structure in long time cycle process, which are all negative factors for the outstanding SCs electrode materials …”

Facile Synthesis of Ag‐Decorated Ni3S2 Nanosheets with 3D Bush Structure Grown on rGO and Its Application as Positive Electrode Material in Asymmetric Supercapacitor

“…Carbon materials, transition metal oxides, and conductive polymers are the typical SCs materials, which have been extensively studied in the past decade . Among various electrode materials, Ni 3 S 2 is an especially attractive candidate for SCs owing to its high theoretical specific capacitance, low cost, and environmentally friendly nature . However, the reported Ni 3 S 2 ‐based materials usually exhibited poor electrical conductivity and unstable structure during redox reaction process, and therefore, it is difficult to achieve the theoretical specific capacitance value.…”
