Abstract
NaxMg0.2Mn0.8O2-cathode material for Na-ion batteries is based on a NaxMnO2 layered oxide substituted with Mg2+ ions. This substitution stabilizes the crystal structure remarkably. Substitution of Mn with Mg also enhances the role of oxygen in constituting electronic states around the Fermi level and its role in the electrochemical process, leading to the improvement of its capacity. More details can be found in article number 2300139, Gabriela K. Wazny, Janina Molenda, and co-workers.
