“…Voltage losses due to lithium ion transport were ignored in a number of earlier studies on modeling LOB discharges [12,16], since the concentration of lithium (typically ~1 M) greatly exceeds that of oxygen in an aprotic electrolyte (~10 −3 M) [17]. However, models that explicitly incorporate parameters describing lithium ion transport were developed later [18]. In contrast, there has been no modeling the LOB discharge curve under conditions where the concentration of lithium cations is a determining factor that influences discharge behavior.…”

A simplified model of lithium-oxygen battery (LOB) discharging is described. Presenting the positive electrode as a monoporous medium characterized by two parameters (porosity and pore radius) allows the study of lithium peroxide formation to be limited to a single pore. A unique aspect of this model is the LOB discharge curve being considered in a broad range of conductivities for a lithium-containing electrolyte. The current density and electrolyte conductivity are considered the core model parameters of LOB discharging. Experimental dependences are investigated for LOB discharge capacity and electrolyte conductivity on the concentration of lithium in an aprotic medium. Based on the results from modeling and experimental data, it is suggested which limiting factors might be responsible for extremely low allowable current densities during LOB discharging.

“…Li-air batteries have potential to power various applications in the future, most especially solar-powered aircraft and electric vehicle, mainly because of their great theoretical energy density of 11680 Wh/kg at average, than those of the existing batteries. The Li-air battery high energy density is a remarkable technological breakthrough when compared with the energy density of gasoline as 13000 Wh/kg (Tan et al 2017). It shows that Li-air battery is the key to solar-powered human-crewed aircraft to compete with the conventional aircraft in the nearest future.…”

This paper reviews various power device components of solar-powered aircraft such as photovoltaic (PV) cells, maximum power point tracker (MPPT) and rechargeable batteries. The various power device components were highlighted, and the ones applicable to aircraft were analyzed, based on criteria as efficiency for photovoltaic cells; energy densities about rechargeable batteries; and maximum power point tracker on quick response to achieve maximum power point on I-V curve. Emerging technologies like photovoltaic cells, thin film cell, organic photovoltaic cell, multi-junction cell and silicon quantum dot cell, with the future potential of high efficiencies that can be used in solar-powered aircraft, were all examined. Regarding battery technology, Lithium-air battery (Li-air) was reported as having great opportunities for high energy densities capable of improving the efficiency of the solar-powered aircraft, for the greater prospect of the aviation industry. The design of efficient power device for solar-powered aircraft application is proposed. Gallium Arsenide (GaAs) solar cells were used because of its high energy conversion efficiency of 30 to 40%. A smart and intelligent MPPT Artificial Neural Network (ANN) is chosen because of its efficiency in partial shading and fast response and speed. The Li-air rechargeable battery is proposed because of its theoretical energy density of 11680 Wh/Kg.

Rechargeable aprotic lithium (Li)-O batteries with high theoretical energy densities are regarded as promising next-generation energy storage devices and have attracted considerable interest recently. However, these batteries still suffer from many critical issues, such as low capacity, poor cycle life, and low round-trip efficiency, rendering the practical application of these batteries rather sluggish. Cathode catalysts with high oxygen reduction reaction (ORR) and evolution reaction activities are of particular importance for addressing these issues and consequently promoting the application of Li-O batteries. Thus, the rational design and preparation of the catalysts with high ORR activity, good electronic conductivity, and decent chemical/electrochemical stability are still challenging. In this Review, the strategies are outlined including the rational selection of catalytic species, the introduction of a 3D porous structure, the formation of functional composites, and the heteroatom doping which succeeded in the design of high-performance cathode catalysts for stable Li-O batteries. Perspectives on enhancing the overall electrochemical performance of Li-O batteries based on the optimization of the properties and reliability of each part of the battery are also made. This Review sheds some new light on the design of highly active cathode catalysts and the development of high-performance lithium-O batteries.
