Most P2-type layered oxides exhibit Na+/vacancy-ordered superstructures because of
strong Na+–Na+ interaction in the alkali metal layer and charge ordering in the transition …

This paper gives an overview of the research carried out on lithium and sodium layered
materials as positive electrodes of lithium (sodium)‐ion batteries. It focuses on the solid …

Abstract Na 0.67 Mn 0.65 Fe 0.35-x Ni x O 2 as a Na storage cathode material was prepared
by a sol-gel method. The XRD measurement demonstrated that these samples have a pure …

Large-scale high-energy batteries with electrode materials made from the Earth-abundant
elements are needed to achieve sustainable energy development. On the basis of material …

The electrochemical properties of the P2-type Na x Mn1/2Fe1/2O2 (x= 0.62) phase used as
a positive electrode in Na batteries were tested in various voltage ranges at C/20. We show …
