Aqueous aluminum (Al) batteries are promising as a low cost, high energy density, and safe energy storage solution. However, significant challenges persist in using Al anodes with water-based electrolytes in acidic regimes. Several approaches have been put forward to resolve these obstacles, but there is an ongoing debate on their viability. Here, we outline the current understanding of the best-performing systems and suggest future research directions.
