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.

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: 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.

This book was released on 2019 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid increasing consumption of fossil fuels since the industrial revolution has brought about environmental and ecological contamination and its depletion, thus, humankind must stop to utilize more clean and renewable energy such as solar, hydraulic power, wind power as alternative. In this case, an effective and efficient medium is a must since those sorts of renewable energy are difficult to be stored and utilized in a standard way. As the invention and improvement of battery, electrical power come up to be the chosen solution. Therefore, electrical vehicles are already commercialized for a long time and growing up rapidly, grabbing the market share from traditional Inner Combustion Engine vehicles. Among the various battery chemistries, Lithium-ion Batteries (LIBs) have acquire most of attention from both academia and industry. With a similar mechanism, Sodium-ion Batteries (SIBs) are acting as an alternative for LIBs for their low cost. However, the current battery performance cannot satisfy the market of electrical vehicle and consumer electronics, thus, energy density and power density as two of the crucial factors for battery performance must be enhanced. To address these issues, the anode of LIBs and SIBs need to be improved. In this dissertation, novel ideas for anode materials design were given, towards not only the current anode modification, but next generation anode production as well. With a high theoretical capacity of 2595 mAh g-1 from alloy reaction, phosphorus is one of the most promising candidates as next generation anode material for lithium/sodium ion battery. Nonetheless, it is suffering volume expansion (300% for LIBs and 500% for SIBs) and low conductivity during cycling, leading to sacrificed robustness of the electrode. Herein, we developed an efficient and effective high energy ball milling route to crystalline phosphorus within carbon matrix as anode material for LIB and SIB. The special structure offers many advantages: enhanced the conductivity; shortened distance for Li+ or Na+ diffusion; buffered volumetric expansion and more stable structure. Benefitting from the merits, the composite delivers a capacity over 1000 mAh g-1 for about 300 cycles at a specific current of 1 A g-1. Both half-cell and full cell cycling test show an 80% retention around 300th cycle. More essentially, crystalline phosphorus can be still found after many cycles. As-prepared material also delivered a high sodium capacity over 700 mAh g-1 over 300 cycles. For increasing utilization in electrical vehicles, the limitation of power density has become a severe issue for LIBs. Therefore, LIBs with advanced high rate performance is highly desirable. A major issue for developing high rate battery is the performance of anode as their sluggish intercalation kinetics. Herein, we provide a new strategy for advanced performance LIB anode design and its demonstration. To fabricate anode with both high energy and power density, two different materials with each character respectively were mixed to achieve the goal, meanwhile, they need to have different charge and discharge plateaus. As the redox plateaus of these materials are different, the electrochemical interaction will occur when they are being charged or discharged as composite, thus enhance the performance as anode for LIBs. Phosphorus-carbon composite and commercialized LTO were utilized to demonstrate this strategy. The current anode system in commercialized LIBs are difficult to be substituted in the near future because of their low charging potential which leads to a high energy density for full cell. In this case, the development of LIBs in EV are highly depends on modification of the current system in recent years. Therefore, we developed a new route for graphite anode improvement with the additive of Metal-organic Framework (MOF). With its special structure, open metal sites (OMS), MOF can immobilize the anion of electrolyte by forming coordination bond, thereby prevents the electrolyte from decomposition, so as to eliminate the byproduct and heat release. With these advantages from MOF additive, the graphite anode performance was improved a great deal especially fast discharging (full cell). And post-cycle characterization explores that MOF keeps higher crystallinity of graphite and lower down the decomposition of the electrolyte LiPF6.
