Supercapacitors: Revealing the Impact of Hierarchical Pore Organization in Supercapacitor Electrodes by Coupling Ionic Dynamics at Micro‐ and Macroscales (Adv. Energy Mater. 24/2021)

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.
