Direct Observation of Reversible Magnesium Ion Intercalation into a Spinel Oxide Host. (17th April 2015) - Kim, Chunjoong
Abstract Direct evidence of Mg2+ intercalation into a spinel‐type Mn2O4 is provided. By combining tools with different sensitivities, from atomic‐resolution X‐ray spectroscopy to bulk X‐ray diffraction, it is demonstrated that Mg2+ reversibly occupies the tetrahedral sites of the spinel structure through the reduction of Mn when the electrochemical reaction is performed.
