LiCl solutions, the Young-Lippmann equation predicts capacitance values consistently larger than that calculated from the simulations. This becomes even more evident for the 2M LiCl solution, where the value of is significantly larger than that of . This is due to a significant change in , which results in a large increase in in the 2M solution. Notably, it can be seen from the tabulated data that is larger at the negatively biased electrode compared to the positively charged surface. This apparent counterintuitive finding (considering the opposite trend in the calculated values, Table ) can be interpreted based on the density profiles discussed in Section 3.1 (see Figure and Figure ). Overscreening occurring at the positively biased surface results in the formation of alternating/overlapping ion and counterion layers (as is evident in the coexistence of Cl -and Li + at positive bias; see Figure and Figure ) that leads to a more diffuse screening of the positively charged surface compared to the negatively biased electrode. This "asymmetric" accumulation of ions in the EDL at opposite signs of surface charge is responsible for the higher values at the negatively biased electrode.
