The electrochemical properties of variously prepared nanoporous carbon, doped diamond-like carbon and metal | surface active compound thin-layer electrodes (electrochemically etched, electrochemically deposited as well as deposited from gases and colloid systems) with large specific surface area will be investigated by electrochemical impedance spectroscopy, chronoamperometry, chronopotentiometry, cyclic voltammetry, BET adsorption, scanning tunnelling and atomic force microscopy, electronmicroscopy, and other methods. Electrochemical behaviour of some new less-toxic solvents and solvent systems (mixtures) and electrolytes will be tested with the aim to use these in the electrochemical double layer capacitors, hybrid capacitors and other electrochemical devices. The various fundamental characteristics (zero charge potential, region of ideal polarizability, limiting Gibbs adsorption, adsorption Gibbs free energy, adsorption and diffusion relaxation times, nature of the limiting stadium, RC- constant, phase angle, effective pore volume, pore size and pore-size distribution, exchange current density, rate constant of heterogeneous reaction, power and energy densities and other parameters will be established and used for the future development of the theory for porous electrodes. Temperature dependence of nanoporous electrode | nonaqueous electrolyte solution interface will be studied. The nanoporous metal | surface active compound | electrolyte pseudocapacitive interfaces will be investigated. These fundamental parameters will be used for the future development and optimisation of technical parameters of the electrical double layer and hybrid capacitors and other electrochemical devices. |
