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.
