Characteristics of an all-solid-state lithium-ion battery prototype

Abstract

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.
