N2 - High-performance, stable, and low-cost ion-conducting membranes (ICMs) are required to drive energy conversion and storage device layout. Herein, we designed a high-performance hollow ZSM-5 zeolite flow battery hybrid membrane and successfully demonstrated upscaled membrane production. The zeolite microporous shell layer inhibits the migration of electrolyte ions, while the hollow core significantly decreases membrane impedance, and the cell-equipped hybrid membrane energy efficiency (EE) surpasses 85% at 120 mA/cm2. Drawing upon this membrane theory and laboratory-scale parameters presented, we further systematically screened and readjusted the substrate type, drying temperature, solid-liquid ratio, and scraper height are further systematically screened and readjusted. Eventually, the roll-to-roll coater equipment successfully realized industrial-size (25 cm × 50 μm × 12 m) membrane production. A flow battery stack (10 × 125 cm2) incorporating the upscaled membrane exhibits an 83% EE and a 200 W average output power. This research contributes to high-performance, large-area-preparable ICMs and drives further diverse energy storage device development.
