💡 Novelty & Significance:
The novelty lies in a stepwise multi-ink 3D-printed dual-gradient MXene/polypyrrole@CNT gel electrode, coupling microlattice spacing and pore-structure gradients to synchronize ion transport with active-site utilization. This suppresses polarization and homogenizes reaction current, enabling high-mass-loading zinc-ion hybrid supercapacitors with 6.2 F cm⁻² and 0.86 mWh cm⁻², offering a scalable framework for high-energy flexible storage.
