Here, R, z, F, and c are the universal gas constant, valency, Faraday constant, and bulk electrolyte concentration, respectively. Beyond this concentration, the lDL shifts to higher values due to a major contribution of larger ion pairs i.e. Bjerrum length. Our observed trend and range of the modified lDL align with the findings of the Debye length (~3-10 nm) in various concentrated electrolytes (1-10 M LiCl, 1-5 M NaCl) reported by Gaddam et al. and Smith et al. , adopting various techniques and models. In addition, the trend of the modified lDL matches the experimental results of various electrochemical properties. A deviation within the same order of magnitude between the modified 𝐶DL and experimental differential capacitance is demonstrated in Figure .
