Lithium-oxygen batteries offer the possibility of achieving twice the gravimetric energy density of lithium-ion batteries. However, several challenges remain to achieve commercially-available lithium-oxygen batteries. Capacity must be optimized by maximizing the formation of Li2O2 discharge product. Side reactions with the solvent and electrode must be suppressed. This study seeks to improve understanding of the mechanisms of Li2O2 evolution and Li-O2 decomposition reactions in order to design strategies to optimize capacity and stability. Decomposition reactions in the solvent dimethyl sulfoxide were studied due to conflicting reports about its stability. Discharged electrodes in dimethyl sulfoxide were aged for varying amounts of time then characterized. Li2O2 reacted with dimethyl sulfoxide to form LiOH and dimethyl sulfone. This demonstrated that dimethyl sulfoxide is unsuitable for commercial application. The study also illustrated the importance of performing aging studies in the discharged condition to determine the stability of Li-O2 battery components. Adding small amounts of water to Li-O2 solvents has been demonstrated to enhance capacity but the effect on stability was not well understood. Discharges were performed in dimethoxyethane and acetonitrile with and without added water. Water caused an unwanted side reaction to form LiOH in acetonitrile but not in dimethoxyethane, due to a higher favorability of deprotonation in acetonitrile. Interactions between capacity enhancing additives and solvent molecules must be carefully studied to avoid side reactions. A model of the two competing mechanistic pathways of Li-O2 discharge was developed to understand how these pathways depend on discharge conditions and solvent properties. The model was fitted to experimental results from rotating ring-disk electrode discharges in order to check that model assumptions were physical. The model demonstrates that Li2O2 film evolution is heavily dependent on solvent properties and that promotion of toroidal Li2O2 primarily depends on slower surface passivation rather than faster solvation of lithium superoxide.

This invaluable book focuses on the mechanisms of formation of a solid-electrolyte interphase (SEI) on the electrode surfaces of lithium-ion batteries. The SEI film is due to electromechanical reduction of species present in the electrolyte. It is widely recognized that the presence of the film plays an essential role in the battery performance, and its very nature can determine an extended (or shorter) life for the battery. In spite of the numerous related research efforts, details on the stability of the SEI composition and its influence on the battery capacity are still controversial. This book carefully analyzes and discusses the most recent findings and advances on this topic.
