Study on Electrochemical Behavior of the Positive Electrode Mg1.2Mn1.8O4 in Magnesium Ion Battery

Abstract

Abstract:

Mg_1.2Mn_1.8O₄ with structure of spinel was synthesized by the method of solid synthesis under high temperature and was studied by X-ray diffraction (XRD) and scanning electron microscope (SEM). The behavior of magnesium ion intercalation in nonaqueous organic electrolyte was studied by means of charge experiments and electrochemical impedance spectra (EIS). The results showed that the performance of magnesium ion intercalating is similar with that of lithium and the electrochemical process is mix controlled.

Key words: Magnesium ion battery, Intercalation reaction, Mg_1.2Mn_1.8O₄, Electrochemical behavior
