3D‐Printed Dual‐Gradient Gel Electrodes Synchronize Ion Transport and Active‐Site Utilization for High‐Energy Zinc‐Ion Hybrid Supercapacitors

ABSTRACT High‐mass‐loading gel electrodes are critical for practical zinc‐ion hybrid supercapacitors, but sluggish ion penetration and depth‐dependent reaction heterogeneity hinder their performance. Herein, we report a dual‐gradient MXene/polypyrrole@Carbon nanotube gel composit...
