Sodium superoxide (NaO₂) based sodium–oxygen batteries (Na‐O₂) possess high theoretical energy density and high energy efficiency that can be an alternative energy storage device to lithium‐ion batteries. However, the state‐of‐the‐art sodium–oxygen batteries are still far from real application due to the limited understanding of the cell chemistry and reaction mechanism. This article reviews the recent advances on NaO₂‐based Na‐O₂ batteries, especially focusing on the reaction mechanism and the stability of NaO₂. The parasitic reactions from the highly active NaO₂ are discussed. It is hoped this provides insightful understanding on the mechanism and the role of the discharge product in Na‐O₂ batteries.

对基于超氧化物的钠氧电池的评论

基于超氧化钠（NaO ₂）的钠氧电池（Na‐O ₂）具有较高的理论能量密度和较高的能源效率，可以作为锂离子电池的替代储能设备。但是，由于对电池化学和反应机理的了解有限，目前最先进的钠氧电池仍未真正应用。本文回顾了基于NaO ₂的Na‐O ₂电池的最新进展，特别关注了NaO ₂的反应机理和稳定性。高活性NaO _2引起的寄生反应讨论。希望这可以提供有关放电产物在Na-O ₂电池中的作用机理和作用的深刻见解。
