Abstract

The composition space between MnO₂, NaFeO₂, and Na[Ni_1/2Mn_1/2]O₂ has been explored with the goal of identifying Earth-abundant single-phase P2 cathode materials. This has led to the identification of two compounds, P2-Na_2/3[Ni_1/3−y/2Mn_2/3−y/2Fe_y]O₂ (y = 1/6, 1/3) which exhibit state of the art specific energies. These materials were further evaluated through galvanostatic cycling and X-ray absorption spectroscopy.
