where ∆𝐺 °f,M 𝑛 and 𝑟 M 𝑛 are the standard Gibbs free energy of M 𝑛 ion and the ionic radii of the M n ion, including positive and negative for n, respectively, and 𝛼 M-Host , 𝛽 M-Host and 𝛾 M-Host are the regression coefficients specific to the layered intercalation compounds with the same host and stacking structure obtained as a result of the screening in Figure . These values are determined for each of them.
