Alkali metal-CO batteries, which combine CO recycling with energy conversion and storage, are a promising way to address the energy crisis and global warming. Unfortunately, the limited cycle life, poor reversibility, and low energy efficiency of these batteries have hindered their commercialization. Li-CO battery systems have been intensively researched in these aspects over the past few years, however, the exploration of Na-CO batteries is still in its infancy. To improve the development of Na-CO batteries, one must have a full picture of the chemistry and electrochemistry controlling the operation of Na-CO batteries and a full understanding of the correlation between cell configurations and functionality therein. Here, recent advances in CO chemical and electrochemical mechanisms on nonaqueous Na-CO batteries and hybrid Na-CO batteries (including O -involved Na-O /CO batteries) are reviewed in-depth and comprehensively. Following this, the primary issues and challenges in various battery components are identified, and the design strategies for the interfacial structure of Na anodes, electrolyte properties, and cathode materials are explored, along with the correlations between cell configurations, functional materials, and comprehensive performances are established. Finally, the prospects and directions for rationally constructing Na-CO battery materials are foreseen.
碱金属-CO 电池将 CO 回收与能量转换和存储相结合，是解决能源危机和全球变暖的一种很有前途的方法。然而，这些电池的循环寿命有限、可逆性差、能量效率低，阻碍了它们的商业化。在过去的几年中，人们对锂-CO 电池系统在这些方面进行了深入研究，然而，对钠-CO 电池的探索仍处于起步阶段。为了促进钠-CO 电池的发展，人们必须全面了解控制钠-CO 电池运行的化学和电化学，以及电池结构与功能之间的相关性。在这里，深入全面地综述了非水相钠-CO 电池和混合钠-CO 电池（包括涉及 O 的 Na-O/CO 电池）中 CO 的化学和电化学机制的最新进展。此后，确定了各种电池组件中的主要问题和挑战，并探讨了 Na 阳极、电解质性质和阴极材料的界面结构设计策略，以及电池结构、功能材料和综合性能之间的相关性。最后，对合理构建钠-CO 电池材料的前景和方向进行了展望。
