For achieving cost-effectiveness, the utilization of printable carbon-based conductive inks has emerged as a critical driver for the industrial advancement of flexible micro-supercapacitors (MSCs). However, the commercial application of carbon-based conductive ink is still limited by their low electrical conductivity and capacitance, attributed to the limited conductive pathways and pore structures resulting from the stacking of conductive materials. Herein, a carbon-based composite aqueous ink based on graphene, multi-walled carbon nanotubes, ...
