Understanding the cation ordering transition in high-voltage spinel LiNi(0.5)Mn(1.5)O(4) by doping Li instead of Ni

We determined how Li doping affects the Ni/Mn ordering in high-voltage spinel LiNi(0.5)Mn(1.5)O(4)(LNMO) by using neutron diffraction, TEM image, electrochemical measurements, and NMR data. The doped Li occupies empty octahedral interstitials (16c site) before the ordering transition, and can move t...
