Abstract

Molybdenum disulfide is obtained by the template method. Its structure and electrochemical properties are investigated. It was found that the working voltage of the LPS for molybdenum disulfide obtained by template method reaches 3 V, the specific capacitance is 180.9 F/g. It was identified that the electric energy storage device the positive electrode of which is molybdenum disulfide obtained by the template method has the discharge specific capacity of 238.9 F/g at a scan rate of 0.001 V/c.

Abstract

Within the framework of the Kronig-Penny model, changes in the electron spectrum of a layered crystal caused by intercalation are analyzed. Special attention is paid to both the geometric changes of the crystal and its energy characteristics during intercalation. The extraordinary behavior of the spectrum caused by the geometric intercalation factor is observed.
