可充非水金属-空气电池因其理论能量密度高而受到广泛关注。然而，大多数报道的金属-空气电池实际上在纯O-2气氛中运行，而环境空气中的CO2和水分会显著影响金属-O-2电池的电化学性能。在CO2污染金属-O-2电池的研究中，人们逐渐发现CO2可以单独作为反应气体使用，即金属-CO2电池可以工作。另一方面，由于CO2对全球气候变化的潜在威胁，特别是其在大气中的浓度不断增加，因此对CO2固定的研究受到关注。在能量存储系统中开发CO2代表了清洁回收和利用CO2的另一种方法。本文旨在及时总结金属-CO2电池的最新成就，并激发新储能系统的新思路。此外，关键问题与反应机制和未来研究的潜在方向进行了讨论。
Rechargeable nonaqueous metal-air batteries attract much attention for their high theoretical energy density, especially in the last decade. However, most reported metal-air batteries are actually operated in a pure O-2 atmosphere, while CO2 and moisture in ambient air can significantly impact the electrochemical performance of metal-O-2 batteries. In the study of CO2 contamination on metal-O-2 batteries, it has been gradually found that CO2 can be utilized as the reactant gas alone; namely, metal-CO2 batteries can work. On the other hand, investigations on CO2 fixation are in focus due to the potential threat of CO2 on global climate change, especially for its steadily increasing concentration in the atmosphere. The exploitation of CO2 in energy storage systems represents an alternative approach towards clean recycling and utilization of CO2. Here, the aim is to provide a timely summary of recent achievements in metal-CO2 batteries, and inspire new ideas for new energy storage systems. Moreover, critical issues associated with reaction mechanisms and potential directions for future studies are discussed.
