is inevitable in Li-CO 2 batteries, [11,12] Li-CO 2 /O 2 batteries, [8,13] and even Li-air batteries. [14] Exception is that the discharge products could be different without the generation of Li 2 CO 3 under specific conditions including protected anodes and effective electrolytes. [15,16] Li 2 CO 3 decomposes to CO 2 when the potential is higher than 3.8 V versus Li/Li + . Notably, O 2 evolution is not detected, as is expected according to the decomposition reaction 2Li 2 CO 3 → 4Li + + 4 e -+ 2CO 2 + O 2 . Instead, superoxide radicals or "nascent oxygen" form during the self-decomposition of Li 2 CO 3 . [12,17] More accurate verification was performed through chemical probes, which qualitatively detected the existence of singlet oxygen ( 1 O 2 ). [18] Parasitic reactions of electrolytes and catalyst degradation were then induced by Li 2 CO 3 oxidation. [12,18] Therefore, efficient air cathodes are expected to change this situation.The introduction of metal nanoparticles could limit side reactions and promote the interaction between Li 2 CO 3 and C. [11,[19][20][21] Beyond this, metal-organic frameworks or surface modified carbon materials also brought unexpected electrochemical performance. [22,23] Therefore, catalysts play important roles in Li-CO 2 batteries. [24][25][26][27][28][29] As mentioned above, self-decomposition of Li 2 CO 3 induced a series of parasitic reactions, and further influenced the stability of catalysts during the operation of Li-CO 2 batteries. Only by clarifying the changes of catalysts in this process can we design more stable Li-CO 2 batteries. In previous reports, mono metal catalysts (Ru, Cu, Au, and Ni) exhibited outstanding activity toward Li-CO 2 batteries and revealed some changes in electrochemical processes. [19][20][21] Nevertheless, there exist shortcomings with mono metal catalysts from materials preparation to electrochemical processes. First, for example, the preparation for monodispersed Ru nanoparticles was often achieved under mild experimental conditions without the generation of stable crystal surfaces, further affecting catalytic activity in Li-CO 2 batteries. [21,30] Second, the incompatibility between the discharge products and mono metal nanomaterials might lead to severe agglomeration and dropping during long cycles. [20,31] In this work, we designed a composite of ruthenium-copper nanoparticles highly co-dispersed on graphene (Ru-Cu-G), and this composite cathode endows Li-CO 2 batteries with low overpotential and excellent cyclability through their synergistic Li-CO 2 batteries are attractive electrical energy storage devices; however, they still suffer from unsatisfactory electrochemical performance, and the kinetics of CO 2 reduction and evolution reactions must be improved significantly. Herein, a composite of ruthenium-copper nanoparticles highly co-dispersed on graphene (Ru-Cu-G) as efficient air cathodes for Li-CO 2 batteries is designed. The Li-CO 2 batteries with Ru-Cu-G cathodes exhibit ultra-low overpotential and can be operated for 100 cycles with ...

“…[1] A rechargeable battery technology which replaced the graphitic carbon host material at the anode with an electrochemically active metal such Li or sodium (Na) could produce substantial increases in storage capacity of the battery anode (from 360 mAh g -1 to 1166 mAh/g (for Na) or 3860 mAh g -1 (for Li)), lowering anode material costs. [2] Such rechargeable metal anode batteries would also enable use of commensurate high-energy cathode materials, such as sulfur (S 8 ) [3][4][5] and oxygen/carbon dioxide (O 2 /CO 2 ) mixtures [6][7][8][9][10][11][12][13] , among others. Use of rechargeable batteries in which an energy-dense metallic anode is paired with an energy-dense cathode offer potential for significant improvements in specific energy on either a volumetric or mass basis (e.g.…”

Metallic sodium is receiving renewed interest as a battery anode material because the metal is earthabundant, inexpensive, and offers a high specific storage capacity (1166 mAh/g at-2.71 V vs the This article is protected by copyright. All rights reserved. 2 standard hydrogen potential). Unlike metallic lithium, the case for Na as the anode in rechargeable batteries has already been demonstrated on a commercial scale in high-temperature Na||S and Na||NiCl 2 secondary batteries, which increases interest. We investigate the reversibility of room temperature sodium anodes in galvanostatic plating/stripping reactions using in-situ optical visualization and galvanostatic polarization measurements. It is discovered that electronic disconnection of mossy metallic Na deposits (-orphaning‖) is a dominant source of anode irreversibility in liquid electrolytes. The disconnection is shown by means of direct visualization studies to be triggered by a root-breakage process during the stripping cycle. As a further step towards electrode designs that are able to accommodate the fragile Na deposits, electrodeposition of Na is demonstrated in non-planar electrode architectures which provide continuous and morphology agnostic access to the metal at all stages of electrochemical cycling. On this basis, we report nonplanar Na electrodes which exhibit exceptionally high levels of reversibility (Coulombic Efficiency > 99.6% for 1mAh/cm 2 Na throughput) in room-temperature, liquid electrolytes.

Toward global sustainable development, lithium-carbon dioxide (Li-CO 2) batteries not only serve as an energy-storage technology but also represent a CO 2 capture system. Since the beginning of their research in this decade, Li-CO 2 batteries have attracted growing attention. However, Li-CO 2 batteries are still in their infancy and are facing many scientific and technological challenges. From a fundamental perspective, the reaction mechanism of CO 2 cathode is not yet clear enough. Technologically, the high overpotential, low power density, poor rate capability, and limited cycle life impede the development of Li-CO 2 batteries for practical applications. Herein, the recent research progress in Li-CO 2 batteries in terms of reaction mechanisms, cathode catalyst design, electrolyte management, and anode protection are first summarized. In light of the state-of-the-art research advances, future perspectives and research directions are then put forward, aiming to provide insightful information for the development of practical Li-CO 2 batteries.
