The main physical properties of these nanostructures were investigated. Method of formation of intercalates in external fields of single and combined action was offered. Regularities of influence of the electric field, applied under process of nanostructure formation, on the properties of the obtained nanostructures were found. Theoretical calculations of predicting the impact of changeable polarization of solvent molecules on structural properties of the electrolyte near charged surface were conducted. The structure of the surface layer was calculated and an influence of electric field was investigated. Both the theoretical model, results of simulation of electronic states of nanostructured materials in the process of adsorption, Li+ ion intercalation, and calculation of charge states, local dipole moments in intercalated atoms were presented. The impact of electronic subsystem of base material and local conditions, formed by doping impurities, in the process of intercalation and charge accumulation in materials-electrodes were established.An analytical description of the intercalated layered system with a packet of improvement, which allowed her to explore the changes in the electronic properties under the influence of intercalation. The model on which the calculation is a simplified version of the periodic Anderson model. Electron correlations, form the structure of the energy spectrum of the impurity, considered by postulating the form of the local Green's function. Use two approximations: single-level model and the model with the advanced level, which takes into account the damping effects. The main restructuring of electrical energy spectrum and the corresponding density of states is reduced to the appearance of the impurity band at the bottom of the primary. At a sufficient distance from the main, the impurity band degenerates to an impurity level, whereas the approach of going on with the restructuring of hybridization zones corresponding edge of the main area. This approach also calculated the electronic contribution to the quantum capacitance intercalation system. Studied its dependence on the chemical potential of the electrons and the influence of factors such as the expansion of the impurity level and the change in temperature. A statistical theory to describe elektrodyfuzionnyh transport processes of ions and electrons in the "electrolyte-electrode" taking into account the spatial heterogeneity and memory effects. Obtained generalized transport equations such as the Nernst-Planck equation for the ions and electrons in the "electrolyte-electrode." A mathematical model describing subdifuziynogo impedance electrolytic systems.
