In this study, by comparing cathode materials with varying degrees of layered ordering, achieved through adjustments in calcination temperature and lithium equivalent, it is shown that although layered ordering increases, it compromises the electronic structure, creating a labile lattice oxygen environment. Fine structural analysis reveals that a higher local Li/O ratio in highly ordered cathode subsequently alters the band structure by narrowing the band gap between Ni 3<em>d</em> and O 2<em>p</em>, which enhances transition metal–oxygen covalency, and reduces the oxygen vacancy formation energy, adversely affecting cyclability.

While several empirical and computational methods are employed for optimization, they are demanding in terms of resources such as materials or computational effort. By leveraging Deep Learning (DL), we can enhance our understanding of the complex manufacturing processes and accelerate its optimization.
