In-situ growth of silicon carbide nanofibers on carbon fabric as robust supercapacitor electrode

Synthesis of 3C/2H/6H heterojunction SiC nanowires with high-performance supercapacitors by thermal evaporation

“…49 This robust cycling performance can be attributed to the excellent thermal stability, thermal conductivity, and chemical resistance of the SiC NWs. 52 The SiC NWs fabricated in this study show excellent capacitive performance and relatively high specic capacitance compared to those reported previously (Table 1). Moreover, the SiC NWs prepared in this work exhibit higher cycling stability than many SiC-based materials and pseudo-capacitive materials reported in the literature (Fig.…”

“…EIS was performed in the frequency range 0.01 Hz to 100 kHz at an AC voltage amplitude of 5 mV. The specific capacitance C (F g −1 ) of the sample was calculated from the CV and GCD curves using eqn (1) and (2), respectively: 52 where m is the mass of the active material (g), i is the current response (A), ν is the potential scan rate (V s −1 ), Δ V is the potential window of discharge (V), I is the current density (A), and Δ t is the discharge time (s).…”

Synthesis and Properties of Silicon Carbide (Review)

“…Today, the synthesis of silicon carbide nanoparticles has become widespread among scientists around the world. There are many developed methods for the synthesis of silicon carbide nanoparticles, for example: sintering [13][14][15][16][17][18][19], combustion [20,21], selective method [22], sol-gel method [23][24][25][26], hydrothermal acid leaching [27], pyrolysis [28][29][30], pyrohydrolysis [31], low temperature synthesis [32,33], microwave synthesis [34][35][36][37], chemical vapor deposition [38][39][40][41][42], in situ growth [43,44], electric arc synthesis [45,46], etc.…”

Silicon Carbide Nanostructures as Potential Carbide Material for Electrochemical Supercapacitors: A Review

“…2D architectures such as nanosheets, nanoflakes, and nanoplates have drawn intensive research interest in the context of a diverse field of applications such as electrochemical supercapacitors, sensors, solar cells, light emitting diods, and photocatalysis [ 83 , 84 , 85 , 86 , 87 , 88 ]. Several synthesis techniques (hydrothermal and/or solvothermal, carbothermal reduction, pyrolysis, and microwave plasma assisted CVD) have been employed to synthesize varieties of 2D nanoarchitectures [ 85 , 89 , 90 , 91 ].…”

“…3C-SiC NWs showed perfect EDLC characteristics within the working potential window of −0.2–0.6 V, had a specific capacitance of 240 μF/cm 2 at a current density of 100 mV/s, and had a capacitance retention of 95% after 2 × 10 5 cycles. Yang et al developed SiC nanofibers on carbon fabric as a supercapacitor electrode, which delivered an outstanding areal capacitance of 4.36 mF/cm 2 at a scan rate of 0.05 V/s, and splendid cyclic durability of 106.51% after 10,000 cycles in KCl electrolyte [ 83 ]. Lust et al synthesized carbon-dioxide -activated SiC-CDC that possessed the specific capacitance of 125 F/g at 1 mA/cm 2 in the organic electrolyte (C2H5)3CH3NBF4 solution in acetonitrile [ 112 ].…”
