Thin-film positive electrode based on vanadium oxides for lithium-ion accumulators

The results of the study of the charge-discharge characteristics and impedance of a solid-state lithium-ion battery of the electrochemical system LiV2O5-LiPON-(Si-O-Al) are presented. It is shown that the features of the charge-discharge curevs are associated with a change in the Fermi level of electrode materials due to a change in the lithium concentration. The results of impedance spectroscopy in the ranges of high, medium and low frequencies are presented and equivalent circuits are proposed.

The results on the study of functional layers of a solid-state thin-film lithium-ion batteries are presented. Thin-films of lithium cobaltite (positive electrode), silicon nanocomposite (negative electrode) and lithium phosphorus-oxynitride (solid electrolyte) were studied by the methods of electron microscopy, energy dispersive analysis and X-ray phase analysis. Technological modes have been determined which make it possible to obtain functional layers with a large-block and columnar structure providing the full depth of electrodes lithiation-delithiation and high ionic conductivity of the solid electrolyte.
