3D-Printed quasi-solid-state microsupercapacitors (MSCs) present immense potential as next-generation miniature energy storage devices, offering superior power density, excellent flexibility, and feasible on-chip integration. However, the challenges posed by formulating 3D printing inks with high-performance and ensuring efficient ionic transport in thick electrodes hinder the development of advanced MSCs with high areal energy density. Herein, we report 3D-printed ultrahigh-energy-density asymmetric MSCs with latticed electrodes, fabricated using Ni-Co-S/Co(OH)
