Low temperature ordering of spinel LNMO cathode material

Long term cycling stability and high energy and power density are key characteristics for battery materials, especially for applications within the field of electric vehicles. LNMO is an interesting candidate material due to its high energy and power density. Depending on the ordering of the atoms within LNMO (mainly Ni and Mn), the material can adopt two different structures. This subtle difference in atomic arrangement leads to differences in the electrochemical behavior, e.g. in the long term cycling stability, where the ordered structure reaches its end of life first. The proposed study aims to investigate the driving force for ordering to occur in LNMO and will be helpful for improving the long term cycling stability of the material in battery applications.
