Abstract

The composition space between MnO2, NaFeO2, and Na[Ni1/2Mn1/2]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 Na2/3[Ni1/3-y/2Mn2/3-y/2Fey]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.
