Synergistic Microstructural and Crystallographic Regulation of V 6 O 13 for Boosting Zinc-Ion Batteries

V6O13 emerges as a highly promising cathode material for aqueous zinc-ion batteries (AZIBs), owing to its unique bilayer topology that offers abundant Zn2+ storage sites and metal-like electronic conductivity. Nevertheless, the electrochemical performance of pristine V6O13 is severely hampered by its intrinsic weak van der Waals interactions, narrow interlayer spacing, and prone-to-agglomeration morphology, leading to slow Zn2+ diffusion and poor structural resilience. Herein, we develop a dual-
