While much of the current research is focused on increasing the energy density of EDLCs, either by maximizing cell voltage or by improving the specific capacitance of the electrodes , the role of electrode material and electrolyte on rate capability, an advantage of EDLCs, is sometimes overlooked. Efficient ionic transport is crucial for maintaining performance at high charge-discharge rates , particularly in thick electrodes that can be used to increase supercapacitor energy density . Mesoporosity (i.e. pores with diameter 2-50 nm) is often suggested as a critical component for efficient ionic transport, serving as a bridge between micropores (where charge storage occurs) and the bulk electrolyte . Ordered mesoporosity, in particular, has been suggested to enhance rate capability by reducing diffusion limitations under high current densities . However, mesopores don't necessarily enhance ionic transport in carbon materials , and the relationship between mesoporosity and rate capability remains insufficiently understood, as characterizing ionic transport within disordered nanoporous carbons poses significant challenges.
