“…The pristine NG spectrum is recovered when the Al/G cell is fully discharged, indicating that the structure of the NG cathode is maintained during electrochemical cycling of intercalation/deintercalation of Al complex ions (Figure g). Corresponding elemental mapping analysis further confirms these results (Figure a,b and Figure d,e). , An evident Cl and Al characteristic X-ray signal is observed in the fully charged state, accompanied by a strong N signal. Compared to the intensity of the characteristic X-ray signal in the NG electrode (full charged state, Figure c), the intensity of the Al, Cl, and N elements is significantly reduced when the Al/G battery is fully discharged (Figure f).…”

Nonaqueous rechargeable Al batteries (RABs) have attracted significant research interest due to the extremely abundant reserves, high theoretical capacities, and low-cost. However, the commonly used nonaqueous RAB ionic liquid (IL) electrolytes are highly air-sensitive and high-cost, which seriously limits their commercial application. Herein, AlCl3–guanidine hydrochloride (AlCl3–GdnHCl), a new low-cost and environmentally friendly deep eutectic solvent (DES) with only 1/40 of the cost of [EMIm]Al x Cl y is introduced into applications for nonaqueous RABs. The battery displays a discharge capacity of 128 mAh g–1 at 0.1 A g–1, which is significantly higher than that of 88 mAh g–1 in [EMIC]Al x Cl y electrolyte. It can reach 124.6 mAh g–1 at 1 A g–1 with the Coulombic efficiency of 99.5% for 1000 cycles. According to the mechanism studies, during the charge–discharge cycle, the fast deposition/dissolution reaction of Al took place at the anode side, while intercalation/deintercalation reaction of [AlCl2(Gdn)n]+ ions and chloroaluminate anions [Al x Cl y ]− (i.e., Al2Cl7 – and AlCl4 –) occurred at the graphite cathode side. With such significant electrochemical behaviors, the AlCl3–GdnHCl DES possesses great potential for use in high-performance storage devices.

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.
