We initially performed searches on compositions with experimental structures. This ensures that sensible parameters were used to operate AIRSS effectively. We used the species pair-wise minimum separations, averaged volume per atom from known structures and symmetry to bias the search towards "chemically sensible regions" enriched with low energy structures. To validate the searches, we compare the our searched structures with the experimental structures that were optimized under identical settings. We also considered theoretical structures from Materials Project (MP) database in the analysis, although it is unclear how these structures are generated. LiNiO 2
