Aluminum‐ion batteries (AIBs), as electrochemical energy storage technologies, are advantageous because of their high theoretical specific capacity, lightweightness, zero pollution, safety, inexpensiveness, and abundant resources, which make them recent research hot spots. However, their electrolyte issues significantly limit their commercialization. The electrolyte choices for AIBs are significantly limited, and most of the available choices do not facilitate the three‐electron‐transfer reaction of Al3+/Al. Thus, this review presents an overview of recent advances in electrolytes, as well as modification strategies for AIBs, to clarify the limitations of existing AIB electrolytes and offer guidance for improving their performances. Furthermore, the advantages as well as limitations and possible solutions for each electrolyte are discussed, after which the future of AIB electrolytes is envisioned.

In the field of rechargeable aqueous aluminum batteries (AABs), carbonyl- and imine-based organic materials have received much attention due to their design flexibility. However, such materials usually face problems such as low capacity and poor stability. For this reason, a simple dehydration condensation method was employed to design a redox-active organic material (ROM)-BQPT (benzo[i]benzo[6,7]quinoxalino[2,3,9,10]phenanthrol[4,5-abc]phenazine-5,10,16,21-tetraone) of π-conjugated structure enriched with multiple C=O and C=N groups. Due to the introduction of more redox-active sites, BQPT can provide an extremely striking capacity of 396.4 mAh g–1 at 0.2 A g–1. Additionally, the abundant π–π structural interactions endowed BQPT with good structural stability and low solubility. In addition, further theoretical calculations confirm that the reorganization of the electron cloud and the expansion of the π-conjugated ligand improve the redox kinetics of BQPT. Combined with ex situ characterizations, its reaction mechanism with Al(OTF)2 + was elucidated. This study provides a significant reference for the design of new types of ROMs.
