3D Printed Ti₃C₂T_x MXene/Cellulose Nanofiber Architectures for Solid‐State Supercapacitors: Ink Rheology, 3D Printability, and Electrochemical Performance

Direct ink writing technology is capable of using 2D MXene to construct 3D architectures for electrochemical energy storage (EES) devices that are normally difficult to achieve using conventional techniques. However, to meet specific rheological requirements for 3D printing, a large amount of MXene is needed in the ink, resulting in a severe self‐restacking structure after drying. Herein, a series of cellulose nanofibers (CNFs) with different...
