Crystallography modulation of aqueous zinc metal anodes can effectively inhibit their dendrite growth and unfavorable side reactions. However, the ability to directly endow commercial Zn foils with specific texture is still lacking. In this study, a grain-size-assisted cold-rolling approach developed reshape unify into strong (002) textured Zn. It revealed that grain size strongly affects formation during plastic deformation. By proper annealing treatment, sizes are controlled at ∼30 μm,...
A high-density neuromorphic computing memristor array based on 2D materials paves the way for next-generation information-processing components and in-memory systems. However, traditional 2D-materials-based devices suffer from poor flexibility opacity, which hinders application of memristors in flexible electronics.

Tunnel-type vanadium oxides are promising cathodes for aqueous zinc ion batteries. However, unlike layer-type with adjustable layer distances, enhancing ion-transport kinetics in tunnels characterized by fixed sizes poses a considerable challenge. This study highlights that the macroscopic arrangement of electrode crucially determines tunnel orientation, thereby influencing transport. By changing material morphology, orientation can be optimized to facilitate rapid diffusion. In...
