Transition metal-based spinel oxides are fascinating supercapacitor electrodes materials
due to their good specific capacitance (C s) and cost-effectiveness. But the spinel materials …

Nickel sulfides and nickel selenides have been widely explored as electrodes for
supercapacitors (SCs) due to their high theoretical capacitances and low cost. However, the …

Abstract The Cobalt sulfide (CoS) nano-particles were synthesized using microwave
assisted route. Powder XRD exhibited mixed phase of Co 3 S 4 and CoS. The average …

Supercapacitors (SCs) have received a great deal of attention and play an important role for
future self-powered devices, mainly owing to their higher power density. Among all types of …

Electric double-layer capacitor (EDLC), as one type of supercapacitor, holds great promises
for fast-charging energy storage devices but suffers from limited specific capacitance. The …

Rose-like Ni 3 S 4 microflowers are successfully synthesized by a novel two-step
hydrothermal technique. X-ray diffraction (XRD), scanning electron microscopy (SEM) and …
