Table indicates that when co-ions and counter-ions are positioned side by side, their size (RH) range from ~0.597 nm to 0.772 nm, corresponding to ~15 % and 49 % of the cumulative surface area of micropores < 1 nm in YP80 F. This size restricts the mutual transport of ions within the pores. Therefore, partial desolvation/desolvation from the outer shell of the ions is expected within these microporous regions. To provide deeper insights into partial desolvation, we first determined the radii of ions
