“…[52][53][54] Zhang et al first introduced graphene into rechargeable Li-CO 2 batteries, showing a higher discharge capacity of 14774 mAh g −1 as compared with that of the electrodes with KB and Super P (Figure 5a,b). [48] The authors proposed that the graphene with its porous structure and excellent electrochemical activity provides efficient diffusion channels, and enough space and active sites for CO 2 utilization and capture. Nevertheless, the kinetic parameters of Li-CO 2 batteries with graphene cathodes still need to be further improved to reach higher efficiency.…”

Li(Na)-CO2 batteries are attracting significant research attention due to contemporary energy and environmental issues. Li(Na)-CO2 batteries make possible the utilization of CO2 and open up a new avenue for energy conver-sion and storage. Research on this system is currently in its infancy, and its development is still faced with many challenges in terms of high charge potential, weak rate capability, and poor cyclability. Moreover, the reaction mechanism in the battery is still unclear and hard to determine, due to the generation of carbon along with metal carbonates on the cathode. In this review, the authors present the fundamentals and the latest progress related to Li(Na)-CO2 research. Detailed discussions are provided on the electrochemical reactions on cathode, cathode materials, and electrolytes. Current challenges and future perspectives on Li(Na)-CO2 batteries are also proposed Disciplines Engineering | Physical Sciences and Mathematics Publication DetailsCai, F., Hu, Z. & Chou, S. (2018 [17][18][19][20][21][22][23][24][25][26][27][28] As a new battery technology, metal-air batteries still face a number of problems, such as poor cycling performance, decomposition of electrolyte, high overpotentials etc. [29][30][31] It is well known that metal-air batteries with an open cell structure can generate power by the electrochemical reaction between metal and oxygen from the atmosphere. Using ambient air as the cathode for metal-air batteries, however, brings even more problematic molecules into the battery system. For example, moisture and CO 2 from the air easily react with the metal and discharge products to form insulating metal hydroxides and metal carbonates at the cathode, which can induce low energy efficiency and poor cycling stability. [32] Thus, most metal-air batteries in laboratories today run in a pure oxygen environment instead of ambient air.Although the concentration of CO 2 is low in ambient air (only 0.03 vol%), [33] CO 2 is known to be more soluble in organic electrolytes than O 2 (≈50 times higher than O 2 ), [34] resulting in the high possibility of CO 2 participation in battery reactions. Considering the influence of CO 2 on the operation of metalair batteries, researchers have focused on metal-CO 2 batteries that utilize an O 2 /CO 2 mixture or pure CO 2 as the reactant gas in the cathode, providing us with a new platform for electrical energy generation and CO 2 conversion and utilization. [35][36][37] At present, Li(Na)-CO 2 batteries have attracted most attention in relation to the development of primary metal-O 2 /CO 2 batteries to achieve rechargeable metal-CO 2 batteries.[38-50] The Li(Na)-CO 2 battery exhibits a high theoretical energy density of 1876 Wh kg −1 (1.13 kWh kg −1 for Na) based on the reaction of 4Li(Na) + 3CO 2 ↔ 2Li(Na) 2 CO 3 + C. [36,44] The operation of a rechargeable Li(Na)-CO 2 battery, however, is faced with the critical challenges of the poor round-trip efficiency and the decomposition of electrolyte caused by high charge overpotential, as well as o...

We report a non-aqueous lithium-oxygen battery with its cathode made of a RuO2 nanoparticle-decorated buckypaper (weaved with carbon nanotubes). Compared with conventionally slurry-formed cathodes, the present cathode has two striking features: i) no binder is required, avoiding the problems of surface-loss and instability due to the introduction of a polymeric binder; and ii) no additional current collector is needed, increasing the practical specific capacity. The present battery demonstrates a discharge plateau of 2.56 V and a charge plateau of 4.10 V at a current density of 0.4 mA cm -2 , with a discharge capacity of 4.72 mAh cm -2 (1150 mAh gcathode -1 ). It is also shown that at a fixed capacity of 2.0 mAh cm -2 , the energy efficiency of the battery reaches 71.2%, 65.4%, and 58.0% at the current densities of 0.2, 0.4, and 0.8 mA cm -2 , respectively. Furthermore, the battery is able to operate for 50 cycles at a fixed capacity of 1.0 mAh cm -2 , showing good cycling stability. The results suggest that the RuO2 nanoparticle-decorated buckypaper cathode offers the promise for a high-practical specific capacity, high-energy efficiency, and stable electrode in non-aqueous lithium-oxygen batteries.

“…Therefore, the safety of Li-O 2 battery can be improved without sacrificing the electrochemical performance.

[33][34][35] Whereas, the obvious difference from cycling stability of the cells using GPE and liquid electrolyte at the current density of 200 mA g -1 is displayed in Figure 5a and b, in which more than 50 cycles is achieved using GPE, while only 15 cycles by using liquid electrolyte. Therefore, in contrast with conventional liquid electrolyte, significantly enhanced cycling stability is achieved in combination with the use of GPE, which is predominantly derived from the absence of flooded air electrodes and the increase of oxygen diffusion, together with the suppression of the dendrite formationduring cycling.…”

Nonaqueous Li-air battery, as a promising electrochemical energy storage device, has attracted substantial interest, while the safety issues derived from the intrinsic instability of organic liquid electrolytes may become a possible bottleneck for the future application of Li-air battery. Herein, through elaborate design, a novel stable composite gel polymer electrolyte is first proposed and explored for Li-air battery. By use of the composite gel polymer electrolyte, the Li-air polymer batteries composed of a lithium foil anode and Super P cathode are assembled and operated in ambient air and their cycling performance is evaluated. The batteries exhibit enhanced cycling stability and safety, where 100 cycles are achieved in ambient air at room temperature. The feasibility study demonstrates that the gel polymer electrolyte-based polymer Li-air battery is highly advantageous and could be used as a useful alternative strategy for the development of Li-air battery upon further application.
