Li-air batteries have attracted interest as energy storage devices due to their high energy

and power density. Li-air batteries are expected to revolutionize the automobile industry (for

use in electric and hybrid vehicles) and electrochemical energy storage systems by surpassing the

energy capacities of conventional Li-ion batteries. However, the practical implementation of Li-air

batteries is still hindered by many challenges, such as low cyclic performance and high charging

voltage, resulting from oxygen transport limitations, electrolyte degradation, and the formation of

irreversible reduction products. Therefore, various methodologies have been attempted to mitigate

the issues causing performance degradation of Li-air batteries. Among myriad studies, theoretical

and numerical modeling are powerful tools for describing and investigating the chemical reactions,

reactive ion transportation, and electrical performance of batteries. Herein, we review the various

multi-physics/scale models used to provide mechanistic insights into processes in Li-air batteries

and relate these to overall battery performance. First, continuum-based models describing ion

transport, pore blocking phenomena, and reduction product precipitation are presented. Next,

atomistic modeling-based studies that provide an understanding of the reaction mechanisms in

oxygen evolution reaction (OER) and oxygen reduction reaction (ORR), as well as ion–ion interactions

in the electrolyte, are described.
