a) Surface charge density, b) differential capacitance, c) average cation and anion densities inside the nanopore, and d) the energy stored per unit of surface area for an EDLC containing a 1.0 m organic electrolyte from coarse‐grained classical DFT. Pore size is D = 0.6 nm; both cations and anions are at 0.5 nm in diameter. δE represents the ion transfer energy from the bulk reservoir into the nanopore. In (c), the solid lines are average densities inside the pore for the counterions, and the dashed lines are for the coions. Reproduced with permission.154 Copyright 2016, IOP Publishing.
