Although lithium-ion batteries are widely used in energy storage systems, research into next-generation battery technologies has gained significant attention because of their high cost and critical safety concerns. Among various next-generation batteries, aqueous zinc-ion batteries (AZIBs) are regarded as highly promising due to their inherent safety, low cost, and high theoretical capacity (820 mAh g-1, 5854 mAh cm-3). Despite these attractive advantages, the practical commercialization of AZIBs remains hindered by their limited cycle life, primarily due to dendrite growth and side reactions such as hydrogen evolution reaction, corrosion, and byproduct formation. In recent years, various strategies have been explored to extend the cycle life of AZIBs, including protective coatings, separator modification, and electrolyte additives. Metal oxides, characterized by their excellent hydrophilicity, chemical stability, and affordability, have emerged as effective materials for addressing main issues in AZIBs and enhancing their cycle life. This review aims to present the diverse strategies in which metal oxides have been utilized to extend the lifetime of AZIBs, and to provide explanations of the underlying mechanisms.
