Abstract 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 importance of cell design in addressing the obstacles of Al−air batteries is emphasized. Subsequently, the impact of operational parameters on improving electrochemical performance of Al−air batteries is summarized. Last, a perspective on future research directions is proposed.
