The oxygen redox (OR) reaction is a promising concept for improving battery energy density, however oxygen activities are generally considered detrimental to the stability and kinetics of batteries. Studies of OR activities often mix the lattice OR with other oxygen-involved reactions, such as gas release, radical oxygen evolution and surface reactions, further shadowing the true property of the practically meaningful lattice OR activities. Here, based on high-efficiency mapping of resonant inelastic X-ray scattering (mRIXS) of both the transition-metals and oxygen, we distinguish and quantify the lattice OR activities Na0.6[Li0.2Mn0.8]O2.
