AbstractMn3O4 is a possible candidate for use as an electrode material and has been found to undergo structural transformation during electrochemical cycling. Clarifying the transformation process is important in developing methods for improving electrochemical performance. Here, using scanning transmission electron microscopy (STEM) combined with the electron energy loss spectroscopy (EELS) technique in aberration-corrected TEM, we succeeded in tracking the structural evolution at an atomic-scale and identified the intermediate stage as rock salt-structured MnO. A reasonable route was deduced via which the spinel Mn3O4 was transformed firstly into Mn0 and then into MnO2. (C) 2016 Elsevier B.V. All rights reserved.
