Recent Advances of Metal-Organic Frameworks and Derivatives for Rechargeable Aluminum Batteries

In light of cost-effectiveness, high volumetric capacity, and abundant supplies on Earth of aluminum metal, the rechargeable aluminum battery (RAB) represents a cutting-edge alternative for energy storage devices. RABs have achieved significant progress as a result of tireless efforts; however, challenges like as expensive ionic liquid electrolytes, a restricted voltage window of aqueous electrolytes, corroded anode, and rapid capacity degradation limit their practical applications. In terms of increasing RAB mileage, electrode materials can be regarded as the foundation of battery performance. Metal-organic frameworks (MOFs), which have customizable topologies, multiple active sites, and various metal centers and ligands, are promising electrode materials. Herein, for the first time, we deliver in detail the recent advancement of MOFs in RABs. The relationship on structure-properties-performance of MOFs is thoroughly discussed. MOF and MOF-derived electrode materials are first summarized. In aluminum sulfur/selenium batteries, MOF can serve as a host to capture the sulfides or selenides. Furthermore, the MOF as catalysts for aluminum-air batteries are provided. Then we focused on the challenges and opportunities that RABs would face in the future, and some prospects are presented. We believe this account will facilitate the exploration of MOFs in RABs and give more inspiration for discovering advanced RABs.
