Several techniques have been employed to analyze the pore structures of nanoporous carbon materials, each with inherent limitations. Gas physisorption, the standard method for evaluating pore size distribution, relies on small gas molecules that may overestimate the surface area and transport pathways accessible to larger electrolyte ions . Pair distribution function (PDF) analysis is effective for probing short-range atomic structures but is less suited for investigating long-range pore connectivity or network organization . Crystallographic techniques like X-ray diffraction (XRD) are similarly limited by the lack of long-range order in amorphous carbons, while advanced tomographic methods, such as focused ion beam (FIB) nanotomography, are restricted in resolution and cannot resolve micropores ( < 2 nm) .
