In a three-electrode test system, the MXene-decorated 3D-printed electrode showed a capacitance of 30.2 mF/cm² at a current density of 0.1 mA/cm². The MXene layers could provide higher capacitances due to their pseudocapacitive charge storage mechanism and high metallic conductivity. Herein, we designed a conductive carbon black-based 3D-printable filament for use as a free-standing electrode after fused deposition modeling (FDM) printing, solvent activation, and MXene coating. Among the various 3D-printing techniques, FDM is a promising method for upscaling due to its low cost and maturity in industry. Three-dimensional (3D) printing offers a unique approach to fabricating free-standing and complex structured electrodes for high-performance micro-supercapacitors (MSCs).
