“…[130] Similarly, a rechargeable hybrid Na-CO 2 battery was successfully prepared with N-doped single-walled carbon nanohorns (N-SWCNH) as a cathode catalyst and Na superionic conductor (NASICON) solid electrolyte as a separation medium for hybrid electrolyte systems. [131] The Na-CO 2 battery exhibited a low discharge/charge voltage gap (0.49 V) and a high discharge capacity of 2293 mA h g −1 , and no significant degradation was observed after 100 cycles. N-doping improved the wettability, electron affinity, and CO 2 adsorption/desorption capabilities of SWCNH.…”

Nevertheless, these electrochemical systems usually show unsatisfactory energy conversion efficiency, on account of the thermodynamic stable CO bond in CO 2 molecule (≈806 kJ mol −1 ), endothermic reaction with a high barrier, and multielectron/proton transfer control on the catalyst surface. [13] In this regard, direct CO 2 electrochemical reduction is conducive to capture CO 2 , reduce CO 2 accumulation, boost reaction kinetics, and enhance energy conversion efficiency synchronously. Among all explored systems for CO 2 electrochemical reduction, metal-CO 2 batteries have become a new hotspot because of the independence of real-time electricity input to drive CO 2 conversion [14] and the high energy density of whole cell. Although the research state of these techniques is quite primary, the unique features of fixating CO 2 gas and reserving energy underpin these techniques to alleviate energy issues and climate crises simultaneously. The metal-CO 2 batteries are similar to the electrochemical CO 2 reduction technology in achieving the CO 2 cycle; however, they have the advantage of allowing intermittent electricity input. Furthermore, metal-CO 2 batteries show promising prospects in the future [15] by conversing excessive CO 2 into value-added chemicals, storing surplus electricity from other power supply systems (e.g., fossil fuels, nuclear, and renewable power), and balancing the energy storage and carbon cycle.The origin of metal-CO 2 batteries is based on the addition of CO 2 in Li/Na-O 2 batteries to promote the discharge capacity and energy density. The first article of the primary Li-CO 2 battery with pure CO 2 supply with a nonaqueous electrolyte at moderate temperatures was reported in 2013. [16] Since then, diverse rechargeable metal-CO 2 batteries used various metals anode was constructed and systematically analyzed in the past few years [17] As such, with the introduction of carbon-based materials and metal-based materials, such as graphite, carbon nanotubes (CNTs), and precious metals, as catalysts for the reaction, the performance of metal-CO 2 batteries have been significantly improved, showing great potential in the area of efficient energy storage and electricity supply. [18][19][20][21] After that, the first rechargeable aqueous Zn-CO 2 battery was reported, which can realize the reversible conversion between CO 2 and liquid HCOOH and verified with the application prospects of metal-CO 2 batteries in the production of highly selective carbon-containing compounds. [22] Metal-CO 2 batteries are among the most intriguing techniques for addressing the severe climate crisis and have matured significantly to simultaneously realize adequate fixation of CO 2 , energy storage, and conversion. Although significant efforts have been made, the practical application of metal-CO 2 battery techniques is still restricted by various tremendous challenges, namely high charge potential, poor rate capability, and reversibility. This review seeks to present a realistic assessment of the most advanced metal-CO 2 sy...

Limiting the carbon emission to the atmosphere requires the efficient utilization of carbonaceous gases and their capture via well-designed platforms. Metal-CO 2 batteries are currently being demonstrated as the route to utilize CO 2 and produce energy simultaneously. In particular, Na-CO 2 batteries are considered an alternative to Li-batteries because of their abundance and low cost. In the current review, the developments in the field of Na-CO 2 batteries are discussed. Carbon dioxide reactions to the decomposition of discharge products have been discussed elaborately. The main discharge products of Na-CO 2 batteries are Na 2 CO 3 and C. In the current review, various strategies are discussed to decompose the discharge products and hence improve cycle stability. The fraction of CO 2 has a substantial influence on cell cycles. A plausible route of battery reaction can be drawn with the help of an ex situ analysis of the electrodes. The final part of the review focuses on the use of solid-state Naion conductors in Na-CO 2 batteries.

“…Although the effect of volatilization can be slowed down by increasing or refilling catholyte, it also increases the practical weight of the battery and leads to unstable cycling performance by changing catholyte concentration. [ 11 ] Therefore, developing a catholyte with high stability and safety is extremely critical for future practical applications of Na‐air batteries. Nowadays, ionic liquid‐based electrolyte, [ 12 ] hybrid solid electrolyte, [ 13 ] quasi‐solid‐state polymer electrolyte, [ 14 ] and adjustable‐porosity plastic crystal electrolyte [ 15 ] have been successfully used to fabricate quasi‐solid‐state/solid‐state Li/NaO 2 battery, [ 16 ] which solves the problem of dendrite growth, liquid electrolyte leakage, and potential H 2 O contamination toward the Li/Na metal anode, opening a new avenue for quasi‐solid‐state/solid‐state metal‐O 2 /air battery.…”

Rechargeable Na-air batteries are the subject of great interest because of their high theoretical specific energy density, lower cost, and lower charge potential compared with Li-air batteries. However, high purity O 2 as a working environment is required to achieve high-performance Na-air batteries, which obstructs their application as a high-energy-density battery. Although aqueous Na-air batteries can operate in ambient air, long cycle and high safety remain challenges for aqueous Na-air batteries because the aqueous electrolyte is volatile. Here, a quasi-solid-state Na-air battery is reported by utilizing a gel cathode, which is composed of single-walled carbon nanotubes and roomtemperature ionic liquids, achieving high safety and long cycling life of 125 cycles (528 h) at a current density of 0.1 mA cm −2 , which is surprisingly better than that of quasi-solid-state NaO 2 batteries. In situ XRD characterizations reveal that water in ambient air is gradually deposited on the surface of the gel cathode to form a water layer, which facilitates the generation of soluble discharge product of NaOH thermodynamically with high conductivity. This work shall be critical to develop and promote the practical application of Na-air batteries, opening a new way to the design of solid-state metal-air batteries.
