Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Lithium batteries have profoundly impacted our daily life, with extensive applications in portable electronics, electrical automotive and grid−scale energy storage applications. In order to achieve much higher energy density than the state−of−the−art, chemistries beyond Li−ion are currently being investigated and need to be made viable for commercial applications. Using metallic Li is among the most prominent choices for next−generation Li batteries, such as Li−S and Li−air systems. After falling into oblivion for several decades because of safety concerns, metallic Li is now ready for a revival. In this talk, I will present my fundamental studies on the failure mechanisms of Li metal, as well as the rational material designs to tackle the problems. In the first chapter, the backgrounds regarding lithium battery research will be introduced. More specifically, the basic principles and the current stages of lithium battery, the future direction of its development, the chemistries at the battery electrode interfaces, and the failure mechanisms will be thoroughly discussed. These aspects lay the foundation for the research presented in this dissertation. In the second chapter, I will present the new findings and fundamental understandings on Li metal failure mechanisms. In the studies, infinite relative volume change of the conventional lithium metal electrode was first identified to be a key contributor to its failure. Then, the failure was further studied from the corrosion points of view, where a new corrosion pathway was identified as the dominant origin of the corrosion in the long term. In addition, typical Kirkendall voids were observed in the corroded Li. The findings were further rationalized by detailed analysis of solid electrolyte interphase formed on the surfaces. In the third part, I presented our efforts in stabilizing Li metal anode by Adv. Mater. development. Based on the new understandings presented in Chapter 2, the stable "host" design for Li metal was proposed and demonstrated. Interfacial modification technology was also developed to further stabilize the electrode/electrolyte interfaces. The two methodologies were proven to be very powerful in stabilizing Li metal. In the next part, battery safety issue was tackled by materials design in advanced battery separators and solid−state electrolytes, both of which were prominent for future batteries employing high energy battery chemistries. On one hand, strong separators with Li dendrite sensing function was developed. On the other hand, solid−state electrolytes with highly improved ionic conductivity and modulus were demonstrated. In the final part of the dissertation, I will present my perspectives and outlooks for the future research in this field. To commercialize the high−energy and safe batteries based on Li 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 Li metal anode a viable technology.

This book was released on 2016-10-06 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Achieving smooth Li-plating without dendrite growth remains to be a grand challenge for developing the next-generation batteries based on Li metal anode. One of the main reasons is our inability to directly model and predict the atomistic and mesoscale mechanisms underlying the complex electroplating process involving concurrent ionic transport, redox reaction, and development of morphological instability. This dissertation presents a phase-field-based multiscale modeling framework to fundamentally understand the dendrite growth mechanism, theoretically interpret the experimental phenomena, and guide the Li metal battery design.The stability and functionality of the solid electrolyte interphase (SEI), i.e. the passivation layer between anode and electrolyte, play critical roles in maintaining a decent battery cycle life as well as calendar life. This becomes even more critical for Li metal anode, which is subjected to large volumetric and interfacial variations during Li plating and stripping. However, there is currently a lack of comprehensive understanding of Li metal/SEI interfaces and their electrochemical and mechanical properties, as well as the SEI growth mechanism at Li metal anode. In this thesis, we employed combined atomistic calculations and experimental techniques to study SEI. Using density function theory (DFT) calculations, we evaluated the interfacial energetics, density of states (DOS), and electrostatic potential profiles of two interfaces, LiF/Li and Li2CO3/Li, at Li metal anode. The calculation results suggest higher interface mechanical stability at the Li2CO3/Li interface but better electron tunneling leakage resistance at the LiF/Li interface. Experimentally, we employed an isotope-assisted time-of-flight secondary ion mass spectrometry (TOF SIMS) method to reveal a bottom-up formation mechanism of SEI growth. It is found that the topmost SEI near the electrolyte formed first and the SEI near the electrode formed later during the initial formation cycle. This growth mechanism was then correlated to the electrolyte one-electron and two-electron reduction reaction dynamics, which in turn explains the formation of two-layered organic-inorganic SEI composite structure. These results provide physical interpretation for the mesoscale phenomena and thus valuable insights for advanced electrode protective coating design.Continuum models have been widely used in attempts to understand and solve the Li dendrite growth problem at mesoscale. However, the limited availability and the accuracy of input physical parameters often limit the predictive power of existing continuum simulations. We hereby developed a multiscale model for a metal electrodeposition process based on the phase-field method and transition state theory by connecting the atomic level charge-transfer physics to the mesoscale morphological evolution. With this model, we discovered that the difference in cation de-solvation-induced exchange current is mainly responsible for the dramatic difference in dendritic Li-plating and smooth Mg-plating. This study not only reveals the physical origin of Li dendrite growth, but also provides a strategy to design dendrite-free Li-ion battery anodes guided by this multiscale model integrating the phase-field method and atomistic calculations.All-solid-state battery is a promising solution to suppress Li dendrite growth. However, recent experimental observation of mechanically-hard ceramic solid electrolytes such as LLZO indicates intergranular dendrite penetration. To understand the Li plating behavior in solid electrolytes, we further extended the multiscale phase-field model of Li dendrite growth by incorporating multiphase solid mechanics and explicit dendrite nucleation. This model helps elucidate the mechanism of major failure modes in a wide range of existing solid electrolyte systems, such as dendrite penetration, intergranular growth and isolated nucleation.

Available in PDF, EPUB and Kindle. Book excerpt: Lithium (Li)-ion batteries have become the pivot of modern energy storage due to their predominant role in powering consumer electronics and electric vehicles. However, with mature manufacturing and production, the energy density of current Li-ion batteries is reaching the theoretical limit. Substantial efforts in both academia and industry are being made to invent next-generation battery chemistries, such as near-future trending Li-ion electrodes including silicon (Si) based anodes, high-voltage LiNi0.5Mn1.5O4 (LNMO) cathode, layered Li-rich Mn-based oxide (LLMO) cathodes, etc. and far-future high-energy Li metal batteries. For near-future Li-ion chemistries such as Si based anodes, LNMO and LLMO cathodes, the existing electrolyte technologies are far from satisfaction. Therefore, liquid electrolyte engineering becomes a pragmatic and imperative approach, and calls for rational design and in-depth understanding of new electrolytes. Li metal battery is a technology existed and commercialized before Li-ion counterpart but forsaken due to safety issues. The kernel, Li metal anodes, endows batteries with high specific energy; however, this is accomplished at the expense of reduced cycle life and increased safety hazards due to the extremely high reactivity and volume fluctuation of Li metal anodes. Therefore, continuous developments of Li metal batteries are demanded to meet the requirements of practical applications. In Chapter 1, background will be provided on current status and recent research efforts of next-generation Li-ion and Li metal batteries. In Chapter 2 and 3, material design artificial solid-electrolyte interphase for protecting Li metal anodes will be discussed. In Chapters 4 and 5, liquid electrolyte engineering and iterative tuning of molecular structure will be elaborated. In Chapter 6, fine tuning of carbonate electrolytes will be demonstrated in the trending Li-ion batteries for near-future practical applications. In Chapter 7, summary and promising directions of future battery developments will be outlooked.

This book was released on 2020 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lithium ion batteries have proven to be a paradigm shifting technology, enabling high energy density storage to power the handheld device and electric automotive revolutions. However relatively slow progress toward increased energy and power density has been made since the inception of the first functional lithium ion battery. Materials under consideration for next generation lithium ion batteries include anionic-redox-active cathodes, solid state electrolytes, and lithium metal anodes. Li-rich cathodes harness anionic redox, showing increased first charge capacity well beyond the redox capacity of traditional transition metal oxides, though suffer from severe capacity and voltage fade after the first cycle. This is in part attributed to oxygen evolution, driving surface reconstruction. Solid-state electrolytes (SSEs) offer the potential for safer devices, serving as physical barriers for dendrite penetration, while hoping to enable the lithium metal anode. The lithium metal naturally exhibits the highest volumetric energy density of all anode materials. Here, we employ simulation and advanced characterization methodologies to understand the fundamental properties of a variety of next generation lithium ion battery materials and devices leading to their successes or failures. Using density functional theory, the effect of cationic substitution on the propensity for oxygen evolution was explored. Improvement in Li-rich cathode performance is predicted and demonstrated through doping of 4d transition metal Mo. Next, lithium phosphorus oxynitride (LiPON), an SSE utilized in thin film batteries, was explored. LiPON has proven stable cycling against lithium metal anodes, though its stability is poorly understood. RF sputtered thin films of LiPON are examined via spectroscopic computational methods and nuclear magnetic resonance to reveal its atomic structure, ultimately responsible for its success as a thin film solid electrolyte. A new perspective on LiPON is presented, emphasizing its glassy nature and lack of long-range connectivity. Progress toward in situ methodologies for solid-state interfaces is described, and a protocol for FIB-produced nanobatteries is developed. Cryogenic methodologies are applied to a PEO/NCA composite electrode. Cryogenic focused ion beam was shown to preserve polymer structure and morphology, enabling accurate morphological quantification and preserving the crystallinity, as observed via TEM. Last, development of in situ solid-state interface characterization is discussed.
