Host-Guest Synergistic Regulation in Functionalized Metal-Organic Frameworks for Efficient Aqueous Zinc-Ion Batteries.

ABSTRACT: Vanadium-based metal-organic framework (V-MOF) cathodes in aqueous zinc-ion batteries (AZIBs) are prone to be pronounced volumetric expansion during charging/discharging processes, which causes structural collapse, capacity fading, and compromised cycling stability. Herein, a series of novel hybrid nanomaterials (Br@P-X) are successfully prepared via a one-step solution method by confining polyoxometalates (POMs) within the pores of the V-MOF and precisely controlling the POMs loadings. The synergistic structural and functional interactions between the porous MOF framework and the uniformly dispersed POMs, as well as the precise tuning of guest POM clusters endow the system with unique electrochemical behavior. The Br@P-16 cathode possesses excellent structural and chemical stability, thus
