“…Upon discharge, MAl(OH) 4 accumulates in the electrolyte, reducing the OH À concentration and, in turn, reducing the ionic conductivity, decelerating the electrochemical reaction kinetics, decreasing the cell voltage as well as specific energy. [28] When the solubility of MAl(OH) 4 in the electrolyte is reached, the formation of insoluble Al(OH) 3 occurs according to (3).…”

“…[2] The realization of a decarbonized economy requires the increase of energy (electricity) generated from renewable energy sources (RES), e. g., solar and wind power, which, however, suffer from seasonal/annual energy fluctuations. [3] The implementation of sustainable, low-cost, and large-scale storage systems that can balance these fluctuations is urgently required, but still full of challenges.…”

Cost‐effective and zero‐carbon‐emission seasonal/annual energy storage is highly required to achieve the Zero Emission Scenario (ZES) by 2050. The combination of Al production via inert‐anode smelting and Al conversion to electricity via Al‐air batteries is a potential option. Although playing an important role in this approach, Al‐air batteries, however, suffer from limited specific energy and inefficient collection of the discharge product. Herein, an important progress in addressing these issues is summarized, emphasizing the importance of non‐material, but rather process‐related aspects. First, a recently reported approach allowing controllable collection of discharge product and electrolyte regeneration is presented. Next, the impact of operational parameters on improving electrochemical performance of Al‐air batteries is summarized. Subsequently, the importance of cell design in addressing the obstacles of Al‐air batteries is emphasized. Last, a perspective on future research directions is proposed.
