Low‐cost and nontoxic deep eutectic liquid electrolytes (DELEs), such as [AlCl3]1.3[Urea] (AU), are promising for rechargeable non‐aqueous aluminum metal batteries (AMBs). However, their high viscosity and sluggish ion transport at room temperature lead to high cell polarization and low specific capacity, limiting their practical application. Herein, non‐solvating 1,2‐difluorobenzene (dFBn) is proposed as a co‐solvent of DELEs using AU as model to construct a locally concentrated deep eutectic liquid electrolyte (LC‐DELE). dFBn effectively improves the fluidity and ion transport without affecting the ionic dynamics in the electrolyte. Moreover, dFBn also modifies the solid electrolyte interphase growing on the aluminum metal anodes and reduces the interfacial resistance. As a result, the lifespan of Al/Al cells is improved from 210 h to 2000 h, and the cell polarization is reduced from 0.36 to 0.14 V at 1.0 mA cm−2. The rate performance of Al‐graphite cells is greatly improved with a polarization reduction of 0.15 and 0.74 V at 0.1 and 1 A g−1, respectively. The initial discharge capacity of Al‐sulfur cells is improved from 94 to 1640 mAh g−1. This work provides a feasible solution to the high polarization of AMBs employing DEL‐based electrolytes and a new path to high‐performance low‐cost AMBs.This article is protected by copyright.

Among emerging rechargeable batteries, rechargeable aluminum‐ion batteries (AIBs) stand out for their high specific capacities and the abundance of aluminum, positioning them as an attractive electrochemical energy storage option. Despite the superior electrochemical performance of non‐aqueous AIBs, aqueous aluminum‐ion batteries (AAIBs) have garnered extensive research interest for their low cost and enhanced safety. Yet, realizing high energy density in AAIBs poses significant challenges. This article systematically reviews strategies and recent advancements in cathodes, anodes, and electrolytes aimed at achieving high energy density in AAIBs. It concludes with a forward‐looking perspective on the design of AAIBs with high energy density and prolonged cycle life, highlighting promising directions for future researches.
