Summary: In this study, a three-dimensional nanocomposite with adjustable micro-mesoporosity was synthesized. The nanocomposite exhibited excellent electrochemical performance and high cycle stability due to its graphene-based structure, which provided low-resistance and short diffusion paths. Additionally, the stability of the three-dimensional porous structure and the even dispersion of MnO2 and Ag nanoparticles contributed to additional active sites and high conductivity in the nanocomposite.

Summary: This study investigated the supercapacitor performances of phosphorus-containing functional groups doped graphene electrodes synthesized in one step and environmentally by Yucel's method. Graphene layers in the mesopore structure were observed, and functional phosphorus and phosphorus including functional groups formed on the electrode surface were characterized. Electrochemical characterization and cyclic charge-discharge tests were performed to determine the cyclic stability and capacitive properties of the electrodes. Results showed an increase in the number of different molecular functional groups on the electrode surface with the number of cycles, and the capacity increase in contrary to expectations due to the formation of polyphosphate structures. The highest areal capacitance was determined as 301.3 mF.cm(-2) for P3-GE50 at 10 mA.cm(-2) current density in sulfuric acid solution.

Summary: Folded nanotubes were grown directly on Ni foam using a two-step hydrothermal method to form activated carbon (AC) and NiCo2S4 composite material with a unique nano-urchin structure. The morphology and structure could be controlled by the duration of the hydrothermal reaction. Characterization of the samples was done using XRD, XPS, EDS, and SEM. The electrochemical tests showed that the 12-hour hydrothermal composites (AC@NiCo2S4-2) had a complete folded nanotube structure, a large number of reactive sites, and better electrochemical properties compared to the 6-hour and 24-hour composites. The AC@NiCo2S4-2 also exhibited a high specific capacitance of 653.9 C g-1 at a current density of 1 A g-1, compared to the capacitance of NiCo2S4 (456.14 C g-1). Furthermore, the AC@NiCo2S4-2 showed improved electrochemical performance and cycle stability after combining with AC, with a capacitance retention rate of 62.84% at 10 A g-1 compared to 1 A g-1 and retaining 84.96% of the initial capacitance after 3000 cycles. Additionally, the hybrid supercapacitor (HSC) based on AC@NiCo2S4-2 and AC electrodes achieved a high energy density of 29.75 Wh kg-1 at a power density of 700 W kg-1 and maintained an energy density of 16.86 Wh kg-1 at a high power density of 7000 W kg-1.
