Fig. 2

a, b STEM-HAADF images of SF-NaMN and NaMN projected along the [100] zone axis. c, d STEM-HAADF images of SF-NaMN and NaMN projected along the [001] zone axis. e Corresponding simulated model of NaMN and SF-NaMN along the [100] zone axis. f Simulated structure of NaMN and SF-NaMN from [001] direction. Atomic EDS mapping of element distributions in the g SF-NaMN and i NaMN, and corresponding normalized element signal density of h, j Mn and Ni atoms along the [100] zone axes. k A section of neutron diffraction (ND) peaks of SF-NaMN and NaMN. The normalization methodology applied to fig h–k is min-max normalization, feature scaling to the [0,1] range.
