Alkali metal–CO2 batteries, which combine CO2 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–CO2 battery systems have been intensively researched in these aspects over the past few years, however, the exploration of Na–CO2 batteries is still in its infancy. To improve the development of Na–CO2 batteries, one must have a full picture of the chemistry and electrochemistry controlling the operation of Na–CO2 batteries and a full understanding of the correlation between cell configurations and functionality therein. Here, recent advances in CO2 chemical and electrochemical mechanisms on nonaqueous Na–CO2 batteries and hybrid Na–CO2 batteries (including O2-involved Na–O2/CO2 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–CO2 battery materials are foreseen.

对非水和混合 Na-CO2 电池的基本理解：挑战与展望
碱金属-CO 2电池将CO 2回收与能量转换和储存相结合，是应对能源危机和全球变暖的一种有前途的方法。不幸的是，这些电池有限的循环寿命、差的可逆性和低能效阻碍了它们的商业化。过去几年，Li-CO 2电池系统在这些方面得到了深入研究，然而，Na-CO 2电池的探索仍处于起步阶段。为了促进 Na-CO 2电池的开发，必须全面了解控制 Na-CO 2运行的化学和电化学电池以及对电池配置和其中功能之间的相关性的充分理解。在这里，非水 Na-CO 2电池和混合 Na-CO 2电池（包括 O 2参与的 Na-O 2 /CO 2 ）的 CO 2 化学和电化学机制的最新进展电池）进行了深入而全面的审查。在此基础上，确定了各种电池组件的主要问题和挑战，并探讨了钠负极界面结构、电解质性能和正极材料的设计策略，以及电池配置、功能材料和综合性能之间的相关性成立。最后，对合理构建Na-CO 2电池材料的前景和方向进行了展望。
