These values of D(Elemental Ratio)max-min were up to four times greater than D(Elemental Ratio)core-edge, reflecting a large oscillation between surface and core. For 63%Ni and 80%Ni, the range of values of D(Elemental Ratio)max-min were closer to D(Elemental Ratio)core-edge reflecting smaller oscillations in composition from surface to core than 86%Ni. The reduced oscillations in concentration could indicate that additional compositional layers in the precursor state led to more even elemental diffusion during lithiation aided by the greater distance between surface to core composition.
