For the intensive development of scientific and technological progress, it is necessary to use new materials with unique desired properties, such as high sorption ability, superconducting properties, high ability to accumulate electric charge, etc. Despite the intensive development of electrical engineering and an increase in the number of portable electronics, it is necessary to use portable sources energy with high rates of charge capacity and cyclability. Currently, one of the most promising is lithium current sources (LCS). Therefore, we can say with confidence that the search for new electrode materials that would provide the above features is undoubtedly an urgent task.

The charge capacity of cathodes of lithium power sources (LIPS) depends on the degree of implementation of the ions in the structural channels, defects and other features of the developed surface of nanosized materials. Interaction ions of lithium with the ions which are on the surface nanoparticles directly dependent on the energy distribution of the valence electrons, particularly a negatively-charged ions. It is important to identify change of these characteristics as a result of methods of synthesis of nano-sized composites.
