Determination of Ni/Mn ordering in LiNi0.5Mn1.5O4 using operando neutron diffraction
We propose to investigate the Ni/Mn ordering in LiNi0.5Mn1.5O4 cathodes as a function of the state of charge using operando neutron diffraction. Our previous work using X-ray diffraction suggests that the cation metal ordering appears in the discharged state, and disappears in the charged state for samples synthesized in the ordered form. We suspect that neutron diffraction will reveal the ordering much clearer than what X-rays are able to. The project is formed in collaboration with an industry partner who will supply the LNMO powder in an ordered and a disordered form, respectively. Pouch cells will then be made to resemble commercial cells as much as possible. Neutron diffraction will be performed directly on the cells during charging and discharging of the cells. We expect to be able to unveil the dependence of the cation metal ordering on the state of charge, as well as providing a more detailed picture of the electrode reactions.
