A top-down approach for fabricating free-standing bio-carbon supercapacitor electrodes with a hierarchical structure

Biomass has delicate hierarchical structures, which inspired us to develop a cost-effective route to prepare electrode materials with rational nanostructures for use in high-performance storage devices. Here, we demonstrate a novel top-down approach for fabricating bio-carbon materials with stable structures and excellent diffusion pathways; this approach is based on carbonization with controll...

The Mathematical Description for CoO(OH)-Assisted Hydroxylamine Electrochemical Determination in Neutral Media

The possibility of hydroxylamine electrochemical determination over a CoO(OH)-modified electrode, accompanied by complex-formation, has been studied from the theoretical point of view. The correspondent mathematical model has been developed and analyzed by means of linear stability theory and bifurcation analysis. It was shown that CoO(OH) may be applied as an efficient electrode modifier i...

Series asymmetric supercapacitors based on free-standing inner-connection electrodes for high energy density and high output voltage.

Asymmetric supercapacitors (ASCs) based on free-standing membranes with high energy density and high output voltage are reported. MnO(2) nanowire/carbon nanotube (CNT) composites and MoO(3) nanobelt/CNT composites are selected as the anode and the cathode materials of the devices, respectively. The ASC has a high volumetric capacitance of 50.2 F cm(-3) at a scan rate of 2 mV s(-1) and a high op...

Free-standing Ag/C coaxial hybrid electrodes as anodes for Li-ion batteries.

Free-standing coaxially structured Ag/carbon hybrid electrodes were prepared as potential anodes for micro-Li-ion batteries, which show excellent electrochemical performance, being essentially due to the beneficial effect of the unique structure, i.e. the Ag-core enhances the flexibility and electrochemical kinetics, while the carbon shell buffers volumetric change during cycling.
