Abstract

A simple one-step solid state reaction way of preparing Nano sized Li2MnO3 powders is investigated. Synthesized products were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). In addition, we have observed that the inferior electrochemical performance of Li2MnO3 upon cycling was attributed to the structural degradation caused by migration of the transition metal (Mn) into the Li layer and repetitive shearing of oxygen layers.
