Abstract:
Extending the voltage window is beneficial for increasing the energy density, but it also imposes more complex structural evolution in P2-type layered oxides. This study enables reversible redox chemistry in a wide voltage range by enlarging the energy level gap between Fe and Mn 3d orbitals, which provides an essential reference for optimizing sodium-ion battery cathodes.

Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...
