LITHIUM-AIR BATTERY TECHNOLOGY 4 Abstract The development of lithium-air batteries with ultra-high theoretical specific energy and energy densities is one of the most promising next-generation power sources, for electric cars and other electronic devices. Future transport is expected to be dominated by lithium-air- battery- powered vehicles, significantly reducing carbon emissions. However, for this to succeed, it is salient that the cycling life, recharging properties and practical capacity of lithium-air batteries are improved considerably. This report provides a perspective on the design criteria, technical challenges, uses, theoretical energy capacities, and the future of lithium-air batteries technology.

LITHIUM-AIR BATTERY TECHNOLOGY 5 Lithium-Air Battery Technology Background Information Clean and more efficient energy has been a hot research topic in the past decade. Among the alternatives, Lithium-air batteries, relying on the theoretically highest specific power, are an extremely promising technology for electric power storage that can make electric cars more affordable and make personal devices such as cell phones requiring less frequent charging (University of Kansas, 2019). However, the research and development in Lithium-air batteries have met with several challenges. A review of these challenges and an evaluation of proposed solutions could be helpful for future research. Introduction Lithium-air battery technology is a type of cell that uses oxidation at the anode and reduction at the cathode, hence inducing a current flow. The pairing of ambient oxygen and lithium is the basis of the development of electrochemical cells that have high specific energy (Asadi et al., 2018). Studies have shown that the theoretical specific energy of non-aqueous type of Lithium-air battery is comparable to that of gasoline, that is, approximately 40.1MJ/kg. The specific energy of gasoline is 46.8 MJ/kg, which is comparable to the theoretical specific energy of Lithium-air battery. Practically, Lithium-air batteries that have a specific energy of approximately 6.12MJ/kg have been demonstrated to be workable (Aurbach, McCloskey, Nazar and Bruce, 2016). This specific energy is at least five times the specific energy of typical lithium-
