Our findings demonstrate that nanoporous carbons with faster ionic transport over long lengthscales deliver superior performance at higher charge/discharge rates, whereas shortrange ionic transport shows no significant correlation with rate capability. Tortuosity measurements characterizing the pore network at the micrometer scale were shown to effectively characterize the complexity of pore pathways and pore interconnectivity, revealing a strong correlation with rate performance. Specifically, nanoporous carbons with lower tortuosity exhibited enhanced rate performance, highlighting the critical role of improved pore interconnectivity in enabling more direct transport pathways for fast-charging supercapacitors. Linking with our recent work which discovered that small graphene-like domains correlate with high capacitance , optimal supercapacitor electrodes may be obtained by combining carbons with small-graphene-like domains for charge storage with low tortuosity pore networks for rapid ion transport . Our study underscores the power of PFG NMR as a robust tool for characterizing tortuosity in amorphous nanoporous carbons and provides valuable insights for the design of supercapacitors and other high-performance electrochemical devices such as sodium-ion batteries. By focusing on the development of low-tortuosity electrodes with well-interconnected pores or efficient transport channels , significant improvements in charging rates can be achieved.
