This thesis describes in-depth theoretical efforts to understand the reaction mechanism of graphite and lithium metal as anodes for next-generation rechargeable batteries. The first part deals with Na intercalation chemistry in graphite, whose understanding is crucial for utilizing graphite as an anode for Na-ion batteries. The author demonstrates that Na ion intercalation in graphite is thermodynamically unstable because of the unfavorable Na-graphene interaction. To address this issue, the inclusion of screening moieties, such as solvents, is suggested and proven to enable reversible Na-solvent cointercalation in graphite. Furthermore, the author provides the correlation between the intercalation behavior and the properties of solvents, suggesting a general strategy to tailor the electrochemical intercalation chemistry. The second part addresses the Li dendrite growth issue, which is preventing practical application of Li metal anodes. A continuum mechanics study considering various experimental conditions reveals the origins of irregular growth of Li metal. The findings provide crucial clues for developing effective counter strategies to control the Li metal growth, which will advance the application of high-energy-density Li metal anodes.

This book provides comprehensive coverage of Lithium (Li) metal anodes for rechargeable batteries. Li is an ideal anode material for rechargeable batteries due to its extremely high theoretical specific capacity (3860 mAh g-1), low density (0.59 g cm-3), and the lowest negative electrochemical potential (−3.040 V vs. standard hydrogenelectrodes). Unfortunately, uncontrollable dendritic Li growth and limited Coulombic efficiency during Li deposition/stripping inherent in these batteries have prevented their practical applications over the past 40 years. With the emergence of post Liion batteries, safe and efficient operation of Li metal anodes has become an enabling technology which may determine the fate of several promising candidates for the next generation energy storage systems, including rechargeable Li-air batteries, Li-S batteries, and Li metal batteries which utilize intercalation compounds as cathodes. In this work, various factors that affect the morphology and Coulombic efficiency of Li anodes are analyzed. The authors also present the technologies utilized to characterize the morphology of Li deposition and the results obtained by modeling of Li dendrite growth. Finally, recent developments, especially the new approaches that enable safe and efficient operation of Li metal anodes at high current densities are reviewed. The urgent need and perspectives in this field are also discussed. The fundamental understanding and approaches presented in this work will be critical for the applicationof Li metal anodes. The general principles and approaches can also be used in other metal electrodes and general electrochemical deposition of metal films.

Lithium ion batteries (LIBs) play an essential role in modern life. Although relatively unknown throughout past decades, LIBs have supplanted several categories of chemically rechargeable batteries including lead-acid, nickel-cadmium and nickel-hydrogen batteries. Nowadays, LIBs dominate the market of portable electronic devices such as mobile phones, digital cameras and laptops. As the price of petroleum keeps increasing, electrically powered or assisted vehicles using LIBs are similarly gaining in the automotive market. However, current state-of-art LIBs using graphite as their electrical anode and Li metal oxides as the cathode are facing major challenges. For example, the current LIBs are approaching their capacity limit. Batteries that can maintain high charge and discharge rates are in great demand, which has not been adequately addressed by modern LIBs. Safety issues with these current batteries are being reported even from some market leaders such as Boeing and Tesla. Herein, several categories of novel anode materials have been investigated in a search for promising candidates to enable evolution of the next generation of lithium ion batteries. This research included silicon-carbon based materials, especially silicon-graphene (Si-G) materials and their derivatives, and transitional metal based materials, e.g., cobalt oxide (Co3O4). In this proposed work, Si-G composites were synthesized via a freeze-drying method; the conditions of the synthesis were controlled and adjusted to obtain a Si-G composite with the most promising morphology as well as battery performance. Based on preliminary results, graphene wrapped silicon electrodes showed significantly improved cycling performance than bare silicon electrodes. At high charge and discharge rates it was found that Si-G composites also showed superior stability and capacity retention over bare silicon electrodes. After 200 cycles, the optimized Si-G composite maintained a capacity retention close to 100%, with a capacity of 800 mAh g-1 at a 0.2 C rate and 600 mAh g-1 at a 1 C rate. This observation was a prominent increase from the performance of commercial graphite-based batteries at a theoretical capacity 372 mAh g-1. Considering the facile fabrication method and increasing use of commercial silicon nano-particles (Si-NPs) into account, Si-G composites could be a promising candidate for the anode material in LIBs. Extended work on the Si-G project also involved further decorations based on the Si-G composite synthesized from the method previously mentioned, as well as improvement on the synthesis method to make it more applicable for industrial purposes. Cobalt Oxide (Co3O4), a transitional metal oxide which has a theoretical capacity of 890 mAh g-1, draws attention as an anode material in LIBs due to its capacity compared to graphite and heavily reduced degradation compared to silicon. A novel electrode fabrication procedure was adopted in this research together with a simple material-synthesizing methodology. Similar to common silicon electrodes, Co3O4 suffers from poor electron conductivity volume change upon cycling. Herein the Co3O4 active material is directly deposited on stainless steel mesh, serving as both a current collector and a substrate for the active material. Through adapting the electrode fabrication process by directly depositing on the stainless steel electron conductor, the traditional conductive carbon material and binder requirements can be avoided. As a result, the process is reduced in both cost and complexity. The presented novel electrode design facilitates both ion diffusion and electron transportation, improving the overall performance of the material in LIBs. After 100 cycles of charge and discharge, Co3O4 on stainless steel mesh shows a capacity around 770 mAh g-1, which is more than twice that of graphite. The capacity retention was around 90% in this case.

Lithium batteries profoundly impact our society, from portable electronics to the electrification of transportation and even to grid−scale energy storage for intermittent renewable energies. In order to achieve much higher energy density than the state−of−the−art, new battery chemistries are currently being actively investigated. Among all the possible material choices, metallic lithium is the ultimate candidate for battery anode, thanks to its highest theoretical capacity. Therefore, after falling into oblivion for several decades due to safety concerns, metallic Li is now ready for a revival. In the first chapter, I introduce the working mechanisms and limitations of the state−of−the−art battery chemistries and provide an overview of promising new battery chemistries based on metallic lithium anode. The current status of lithium metal anode research is also comprehensively summarized. In the second chapter, I discuss one particular failure mode of metallic lithium anode that has long been overlooked by the battery community, which is the infinite relative volume change of the electrode during cycling. To tackle this problem, novel three−dimensional lithium metal−host material composite designs will be demonstrated. Chapter three focuses on further improving the electrochemical performance of three−dimensional lithium metal anodes with surface coatings. Two examples of lithium metal coatings are given, which have been demonstrated effective for protecting reactive lithium from parasitic reactions with liquid electrolytes and mechanically suppressing nonuniform lithium deposition morphology. Chapter four discusses how the physiochemical properties of the solid−electrolyte interphase, dictated by electrolyte composition, affect the electrochemical behavior of metallic lithium. A special electrolyte additive has been discovered to enable high efficiency lithium cycling in carbonate−based electrolytes used exclusively in almost all commercial lithium-ion batteries. Moreover, the mechanisms behind the improved performance have been studied based on the structure, ion−transport properties, and charge−transfer kinetics of the modified interfacial environment using advanced characterization techniques. In Chapter five, I explore a paradigm shift in designing solid−state lithium metal batteries based on three−dimensional lithium architecture and a flowable interfacial layer. The new design concept can be generally applied to various solid electrolyte systems and the resulting solid-state batteries are capable of high−capacity, high−power operations. In the final part of the dissertation, I present my perspectives and outlooks for the future research in this field. The commercialization of high−energy and safe batteries based on lithium metal chemistry requires continuous efforts in various aspects, including electrode design, electrolyte engineering, development of advanced characterization/diagnosis technologies, full−battery engineering, and possible sensor design for safe battery operation, etc. Ultimately, the combinations of various approaches might be required to make lithium metal anode a viable technology.
