MOF-based electrode materials for aqueous zinc-ion batteries: design strategy and future challenges

Abstract

Rechargeable aqueous zinc-ion batteries (AZIBs) are considered the most promising energy storage devices due to their high theoretical specific capacity, safety, and low cost. Metal–organic frameworks are emerging porous materials characterized by adjustable structures and active metal centers. This review summarizes the application of MOFs in the preparation of electrodes for AZIBs, particularly focusing on various design strategies. Moreover, we provide electrochemical performance comparisons under different strategies and propose future development challenges.
