The lithium-sulfur (Li-S) couple is one of the most promising chemistries for realizing the next generation of high energy density rechargeable batteries. Over the last decade, there have been concerted efforts towards solving the issues with the sulfur cathode. However, maintaining reasonable cycle life in practically relevant cell designs with a limited lithium inventory and lean electrolyte supply has proven quite difficult. It can be primarily attributed to the poor reversibility of the lithium-metal anode, which undergoes high-surface area mossy growth mechanisms and severe parasitic side reactions with the electrolyte during plating and stripping. Solving this challenge is key to Li-S batteries realizing their commercial viability. Furthermore, lithium deposition in the Li-S system is uniquely convoluted by the presence of soluble polysulfide intermediates in the liquid electrolyte. In this dissertation, the dynamics of lithium deposition in Li-S batteries are systematically investigated with an anode-free full cell configuration, and the mechanisms underlying the interplay between lithium-electrolyte interfacial chemistry and degradation of lithium inventory are delineated. A generalized strategy involving molecular engineering of polysulfide species and exploiting the intrinsic shuttle effect is developed for improving efficiencies of lithium plating and stripping and cyclability under realistic limited-lithium and lean-electrolyte conditions. In Chapter 1, a general overview of the Li-S battery system is provided, including a description of the electrochemistry of sulfur cathodes, the role and dynamic behavior of lithium-metal anode, and the challenges and opportunities presented by the distinct chemistry of the polysulfide-rich electrolyte. In Chapter 2, general experimental details encompassing cathode preparation, cell assembly, electrochemical measurements, and materials characterization are outlined. In Chapter 3, the anode-free full cell configuration, which pairs a Li2S cathode with a bare current collector and contains no excess lithium, is introduced as the ideal framework for investigating lithium deposition in Li-S batteries. In Chapter 4, the anode-free full cell configuration is used to determine a quantitative estimate of the rate of lithium inventory depletion with cycling. ToF-SIMS measurements reveal the growth of a thick electrolyte decomposition layer with cycling, which blocks ionic access to “dead” metallic lithium underneath. In Chapter 5, the chemistry of lithium-electrolyte interface and its impact on the dynamics of lithium deposition is carefully investigated. Specifically, the critical role of LiNO3 and polysulfides in modulating lithium deposition in Li-S batteries is elucidated. In Chapter 6, the introduction of tellurium as a cathode additive is demonstrated as an effective strategy for improving the cycle life of high energy anode-free, lean-electrolyte Li-S cells. Soluble tellurium containing species are formed, which shuttle to the anode side and form a stabilizing interfacial layer in-situ on lithium surface. In Chapter 7, this molecular engineering approach is further developed by investigating the chemistry of substituting selenium and tellurium into polysulfide species. While Se substitution improves charge-transfer and redox kinetics at the sulfur cathode, Te substitution engenders a substantial improvement in the reversibility of lithium anode. Finally, Chapter 8 concludes with a summary of all the work carried out in this dissertation and a perspective on future Li-S battery research

Over-consumption of fossil fuels has caused deficiency of limited resources and environmental pollution. Hence, deployment and utilization of renewable energy become an urgent need. The development of next-generation rechargeable batteries that store more energy and last longer has been significantly driven by the utilization of renewable energy.This book starts with principles and fundamentals of lithium rechargeable batteries, followed by their designs and assembly. The book then focuses on the recent progress in the development of advanced functional materials, as both cathode and anode, for next-generation rechargeable batteries such as lithium-sulfur, sodium-ion, and zinc-ion batteries. One of the special features of this book is that both inorganic electrode materials and organic materials are included to meet the requirement of high energy density and high safety of future rechargeable batteries. In addition to traditional non-aqueous rechargeable batteries, detailed information and discussion on aqueous batteries and solid-state batteries are also provided.

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.

The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.
