Metal−CO 2 rechargeable batteries are of great importance due to their higher energy density and carbon capture capability. In particular, Na−CO 2 batteries are potential energy-storage devices that can replace Li-based batteries due to their lower cost and abundance. However, because of the slow electrochemical processes owing to the carbonated discharge products, the cell shows a high overpotential. The charge overpotential of the Na−CO 2 battery increases because of the cathode catalyst's inability to break down the insulating discharge product Na 2 CO 3 , thereby resulting in poor cycle performance. Herein, we develop an ultrathin nanosheet MoS 2 /SnS 2 cathode composite catalyst for Na−CO 2 battery application. Insertion of SnS 2 reduces the overpotential and improves the cyclic stability compared to pristine MoS 2 . As shown by a cycle test with a restricted capacity of 500 mAh/g at 50 mA/g, the battery is stable up to 100 discharge− charge cycles as the prepared catalyst successfully decomposes Na 2 CO 3 . Furthermore, the battery with the MoS 2 /SnS 2 cathode catalyst has a discharge capacity of 35 889 mAh/g. The reasons for improvements in the cycle performance and overpotential of the MoS 2 /SnS 2 composite cathode catalyst are examined by a combination of Raman, X-ray photoelectron spectroscopy, and extended X-ray absorption fine structure analysis, which reveals an underneath phase transformation and changes in the local atomic environment to be responsible. SnS 2 incorporation induces S-vacancies in the basal plane and 1T character in 2H MoS 2 . This combined impact of SnS 2 incorporation results in undercoordinated Mo atoms. Such a change in the electronic structure and the phase of the MoS 2 /SnS 2 composite cathode catalyst results in higher catalytic activity and reduces the cell overpotential.

“…The catalytic ability of the Ru/CNT cathode to decompose discharge products of Li–CO 2 and Na–CO 2 batteries to evolve CO 2 gas could be further verified using the in situ gas chromatography–mass spectrometry (GC–MS) characterization during the charging process. The detailed procedure and the utilization of homemade cell for GC–MS characterization have been discussed in the earlier reports. ,, Before the GC–MS measurement, predischarged electrodes of Ru/CNT were prepared using the cutoff capacity of 500 mAh g –1 at 100 mA g –1 . The predischarged Ru/CNT electrodes were utilized to assemble the homemade GC–MS cell and the charging process was performed simultaneously to monitor the evolution of CO 2 , O 2 , and decomposed electrolyte fragments in Li–CO 2 and Na–CO 2 batteries.…”

Alkali metal–carbon dioxide (Li/Na–CO2) batteries have generated widespread interest in the past few years owing to the attractive strategy of utilizing CO2 while still delivering high specific energy densities. Among these systems, Na–CO2 batteries are more cost effective than Li–CO2 batteries because the former uses cheaper and abundant Na. Herein, a Ru/carbon nanotube (CNT) as a cathode material was used to compare the mechanisms, stabilities, overpotentials, and energy densities of Li–CO2 and Na–CO2 batteries. The potential of Na–CO2 batteries as a viable energy storage technology was demonstrated.

Typically, the constant consumption of conventional fossil fuels leads to over-emission of carbon dioxide (CO 2 ) and accelerates the trend of global warming. [2] Therefore, in recent years, researchers from both academia and industry have devoted tremendous efforts to developing new energy systems to reduce CO 2 emission as well as converting CO 2 into valuable chemicals. [3] Among all explored systems for CO 2 reduction, the idea of rechargeable metal-CO 2 batteries exhibits significant promise for effective CO 2 reduction, value-added CO 2 conversion, as well as high-performance energy storage. It is therefore considered a "kill two birds with one stone" strategy and becomes a new research hotspot in areas of both CO 2 reduction and electrochemical energy storage. [3j,4] The first article of a primary Li-CO 2 battery with a nonaqueous electrolyte was reported in 2013. [5] Since then, diverse rechargeable metal-CO 2 batteries using different alkali metal anodes (Li, Na, K) have been constructed and systematically analyzed in the past few years. [6] However, the alkali metals possess high reaction activities, [6g,7] and Li, Na, and K anodes all suffer from dendrite formation during cycling that leads to severe battery safety issues, reduces battery cycle life, and restricts their practical applications. It is urgent to explore new metal anodes for metal-CO 2 batteries with comparatively lower activities and meanwhile being dendrite-free. [8] With that in mind, magnesium metal could be a promising option. On the one hand, Mg possesses a high theoretical volumetric capacity of 3833 mAh cm −3 (vs 2062 mAh cm −3 for Li, 1128 mAh cm −3 for Na, and 591 mAh cm −3 for K), [9] enabling Mg to fix more CO 2 per unit volume. On the other hand, Mg storage in the Earth's crust is abundant (about 2.9%), which is about 1500 times compared to Li (0.002%), resulting in a theoretically significantly lower production cost of Mg batteries. Most importantly, Mg metal anode's dendrite-free nature is favorable for battery safety and long cycle stability. [10] As the rechargeable Mg-CO 2 battery processes the above advantages of high volumetric energy density, high safety, environmental friendliness, and low cost, it is envisaged as a promising strategy for excellent energy storage and effective CO 2 exploitations. [9c] In spite of the favorable factors, there are very few reports in the literature related to Mg-CO 2 batteries with nonaqueous
