In article number 2100700, Muslim Dvoyashkin, Lars Borchardt, and co‐workers apply a combination of diffusion NMR and impedance spectroscopy to quantify the impacts of ionic transport inside and outside pores of model carbons. In contrast to a popular common belief, scenarios are described in which the diffusion inside pores is not the rate‐limiting step for the charge/discharge of supercapacitor devices.
