“…Studies have indicated that a lower resistance and a stable interface can result from melting the metal Li anode onto the NASICON-like LAGP solid electrolyte. [78,83] Similarly, the resistance between Li and garnet electrolyte LLZO fell dramatically from 5822 cm 2 to 514 Ω cm 2 after heating to 175 °C. [119] These results can be attributed to the better compatibility of the Li metal to the rough surface of the solid electrolyte after thermal heating.…”

“…[82] In addition, the cathode material composing of single-walled carbon nanotubes (SCNTs) with SE fabricated by high-energy ball milling maintained a superior cyclability of 1000 mA h g −1 for 10 cycles at RT in air. [83] This finding may be attributed to the small particle size and the intimate contact between SCNTs and SE.

batteries based on intercalation materials cannot meet the demands of long-distance transport (i.e., >300 km).Recently, interest in Li-air [4][5][6] (or Li-O 2 as oxygen is the cathode active component) and Li-S batteries [7][8][9] has increased because of their high theoretical capacities and energy densities, which are suitable for remote transportation. Abraham and Jiang introduced the first rechargeable Li-O 2 battery in 1996, [10] although it drew little interest until Bruce and co-workers proved the rechargeability of Li 2 O 2 . [11] Li-O 2 cells possess significant strength because oxygen gas can be obtained from ambient air. Li-ions react with oxygen according to Equation (1), and Li 2 O 2 is the discharge product with an equilibrium potential of 2.96 V, delivering a large specific energy of 3600 W h kg −1 . Investigations on Li-S cell date back to the 1940s. The insulating nature of sulfur, Li 2 S 2 , and Li 2 S and the solubility of polysulfide intermediates greatly hinder its development. Fortunately, recent studies on new electrolytes and nanostructured material design provide merits and opportunities in developing Li-S batteries. Similar to Li-O 2 batteries, Li-S batteries, which contain inexpensive and abundant sulfur as positive electrode material, produce an average voltage of 2.15 V and possess a theoretical energy density of up to 2600 W h kg −1 , as further indicated by Equation (2). Many studies showed that intermediate polysulfide is produced during the discharge process where Li 2 S is formed as the final product. Typically, Li-O 2 and Li-S batteries both adopt Li metal as anode. The reason is that Li possesses the largest capacity (3860 mA h g −1 ) and the lowest negative electrochemical potential (−3.04 V) versus standard hydrogen electrodes. Thus, Li-O 2 and Li-S batteries are considered to be promising next-generation energy storage systems for PEVs and HEVs However, despite the advantages of Li-O 2 and Li-S batteries, they exhibit ignitability, toxicity, liquid leakage, and volatilization because of their organic liquid electrolyte components. Moreover, Li dendrites form during cycling, resulting in internal short circuit that leads to combustion and even cell explosion. [12,13] More seriously, the charging process in Li-air

Green and renewable resources are more attractive than nonrenewable energy sources, which have been significantly exhausted. In addition, the rapid consumption of nonrenewable fossil fuels will result in the accumulation of CO 2 in the atmosphere and other serious environmental problems. [1] To solve these problems, various types of electrochemical energy storage devices have been developed, such as Li-ion batteries, [2][3][4] Na-ion batteries, [5,6] supercapacitors, [7][8][9][10] and others. [11,12] Among these energy storage systems, Li-ion batteries have attracted attention because of their long cycling life and environmental-friendly properties. As Li-ion batteries were commercialized in 1990, they have been widely applied in various fields, especially electronic devices, resulting in the development of portable electronic devices. [2,13] Recently, electric vehicles (EVs) have attracted attention owing to their zero-pollution property. However, EVs using Li-ion battery systems cannot yet challenge the 300-mile range of the average internal combustion engine. It is very urgent to develop alternative high energy storage devices. The theoretical specific energy of a Li-O 2 battery is 3505 Wh kg À1 when the discharge product is Li 2 O 2 , which is five to eight times higher than that of Li-ion batteries. Even considering the mass of the other battery components, including the positive active material, current collector, and outer packing, the actual special energy of Li-O 2 batteries can reach approximately 500-900 Wh kg À1 . In addition, EVs powered by these batteries have a range of up to 550 km, which is tremendously longer than that achievable with other secondary batteries and the average internal combustion engine. [12] Moreover, their positive active material can be obtained directly from the air, which greatly reduces their cost. As a result, the Li-O 2 battery is regarded as a promising next-generation energy storage system.According to the electrolyte, Li-O 2 batteries are classified as three types, that is, aprotic, hybrid aqueous/aprotic, and all-solid-state Li-O 2 batteries. [14][15][16][17] In this article, nonaqueous Li-O 2 batteries will be discussed. We will elaborate on the structure and mechanism of the nonaqueous Li-O 2 battery. It is composed of a porous positive electrode, nonaqueous Li + electrolyte, and Li metal negative electrode. In the discharge process, oxygen receives electrons and is reduced on the positive electrode, which is also called the oxygen reduction reaction (ORR). The negative metal Li releases electrons to form Li + . Li + moves across the electrolyte, and oxygen combines with the electrons from the external circuit to generate Li 2 O 2 on the cathode surface. Li 2 O 2 decomposes to Li + and O 2 in the charge process, which is the oxygen evolution reaction (OER). [12] Generally, from the respect of reactions on the electrode, electrochemical power sources involve three types, that is, intercalation reaction, conversion reaction, and electrocatalytic reaction (as seen in T...

This review reports on the most updated technological aspects of Li-air battery cathode materials. It provides the reader with recent developments, alongside critical views. The requirements for air-cathodes, as well as the classification and characterization of carbon-based and carbon-free air cathodes, are listed. The effects of two major substituent groups of materials, namely carbon and advanced materials (metals, metal-oxides, metal-carbides, and metal-nitrides) aimed at replacing carbon, are discussed in terms of their chemical and electrochemical stability. The report covers aspects of surface chemistry and structure influence on the electrolyte and discharge products stability. The review also reports on the efforts to suppress side reactions and deterioration of the polymeric binders (if a composite electrode is being considered). This is recognized as a means to enhance Li-air battery performance. The report concludes with an outlook and perspective, providing the readers with some insight on other factors and their impact on the long road toward a viable air-cathode suitable for Li-air battery operations.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adfm.201808303.respectively. [1] The configuration of an aprotic LOB is based on coupling lithium metal anode and air-breathing cathode in a non-aqueous electrolyte system. The electrochemical reactions occurring during discharge are complex multistep reactions and may involve dissolved and/or adsorbed species alongside parasitic reactions. [2][3][4][5] Oxygen reduction reaction during discharge largely depends on the cathode and electrolytes characteristics; yet, a dominant process involving a two-electron oxygen reduction reaction (ORR), with the formation of Li 2 O 2 , is reported, according to the following reaction [6] The reverse process, namely lithium peroxide oxidation, occurs upon charging. The formation/decomposition of Li 2 O 2 during discharge/charge is often accompanied by parasitic side reactions, due to instability of the major battery components (cathode, electrolyte, and anode) under operating conditions. [7][8][9][10][11][12] While lithium metal anode corrosion can be mitigated by a protective solid electrolyte (SE) membrane, [13][14][15] the electrolyte and cathode are considered as the most challenging components of LOB. Much efforts have been placed on understanding the role of the electrolyte, its degradation, on Li-O 2 reaction mechanism and battery performance. [16][17][18][19][20] Nonetheless, the high discharge/ charge overpotential and severe capacity loss in the course of cycling are also largely related to the air-breathing cathode. A stable, high surface area, cost-efficient air-electrode with excellent catalytic activities toward oxygen reduction and oxidation is crucial for the development of practical LOB. Cathode materials should be stable, durable, and hold interfaces with minimum surface oxide layers, which can inhibit charge transfer during the charging p...
