Rechargeable Zinc–Air Batteries: Advances, Challenges, and Prospects

Small, Journal Year: 2023, Volume and Issue: 20(4)

Published: Sept. 15, 2023

Abstract Rechargeable zinc–air batteries (Re‐ZABs) are one of the most promising next‐generation that can hold more energy while being cost‐effective and safer than existing devices. Nevertheless, zinc dendrites, non‐portability, limited charge–discharge cycles have long been obstacles to commercialization Re‐ZABs. Over past 30 years, milestone breakthroughs made in technical indicators (safety, high density, battery life), components (air cathode, anode, gas diffusion layer), configurations (flexibility portability), however, a comprehensive review on advanced design strategies for Re‐ZABs system from multiple angles is still lacking. This underscores progress proposed so far pursuit high‐efficiency system, including aspects rechargeability (from primary rechargeable), air cathode unifunctional bifunctional), anode dendritic stable), electrolytes aqueous non‐aqueous), non‐portable portable), industrialization laboratorial practical). Critical appraisals modification approaches (such as surface/interface modulation, nanoconfinement catalysis, defect electrochemistry, synergistic electrocatalysis, etc.) highlighted flexible with good sustainability density. Finally, insights further rendered properly future research directions batteries.
