Abstract The electrochemical storage of energy in various carbon materials (activated carbons, aerogels, xerogels, nanostructures) used as capacitor electrodes is considered. Different types of capacitors with a pure electrostatic attraction and/ or pseudocapacitance effects are presented. Their performance in various electrolytes is studied taking into account the different range of operating…
a b s t r a c t Exceptional electrochemical behavior of carbon/iodide interface has been demonstrated and successfully used in supercapacitor application. This efficient charge storage is based on specific sorption of iodide ions as well as stable reversible redox reactions connected with various possible oxidation states of iodine from -1 to +5. An intriguing effect of iodide ions has been…
Abstract Possibilities of electrochemical energy conversion using carbon nanotubes and related materials in various systems, such as lithium batteries, supercapacitors, hydrogen storage, are considered. It is shown that for these applications the electrochemical properties of multiwalled (MWNTs) and single walled (SWNTs) nanotubes are essentially dominated by their mesoporous character. During…
