Abstract
Additive manufacturing offers new and exciting opportunities for the digital fabrication of energy storage and electrocatalytic devices. Herein, the important role of 3D‐printed low‐tortuosity structures in improving thick electrodes’ electrochemical kinetics (mass transfer and charge transfer) is highlighted. First, the key factors determining the electrochemical kinetics in open porous structures and the commonly used computational and experimental characterization methods for porous structures are reviewed. Then, various 3D‐printed energy storage and electrocatalytic electrodes and devices, focusing on the contribution of low‐tortuosity structure to electrochemical kinetics are featured. Finally, thoughts about the prospects and challenges of 3D‐printed energy storage and electrocatalytic systems are shared.
