Download or read book From Intrinsic to Extrinsic Design of Lithium-Ion Battery Layered Oxide Cathode Material Via Doping Strategies written by Chul-Ho Jung and published by Springer Nature. This book was released on 2022-10-20 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the comprehensive understanding of Ni-rich layered oxide of lithium-ion batteries cathodes materials, especially focusing on the effect of dopant on the intrinsic and extrinsic effect to its host materials. This book can be divided into three parts, that is, 1. overall understanding of layered oxide system, 2. intrinsic effect of dopant on layered oxides, and 3. extrinsic effect of dopant on layered oxides. To truly understand and discover the fundamental solution (e.g. doping) to improve the Ni-rich layered oxides cathodic performance, understanding the foundation of layered oxide degradation mechanism is the key, thus, the first chapter focuses on discovering the true degradation mechanisms of layered oxides systems. Then, the second and third chapter deals with the effect of dopant on alleviating the fundamental degradation mechanism of Ni-rich layered oxides, which we believe is the first insight ever been provided. The content described in this book will provide research insight to develop high-performance Ni-rich layered oxide cathode materials and serve as a guide for those who study energy storage systems.

Book Synopsis Studies on Anionic Redox in Li-Rich Cathode Materials of Li-Ion Batteries by : Biao Li
Download or read book Studies on Anionic Redox in Li-Rich Cathode Materials of Li-Ion Batteries written by Biao Li and published by Springer. This book was released on 2018-12-13 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents studies and discussions on anionic redox, which can be used to boost the capacities of cathode electrodes by providing extra electron transfer. This theoretically and practically significant book facilitates the implementation of anionic redox in electrodes for real-world use and accelerates the development of high-energy-density lithium-ion batteries. Lithium-ion batteries, as energy storage systems, are playing a more and more important role in powering modern society. However, their energy density is still limited by the low specific capacity of the cathode electrodes. Based on a profound understanding of band theory, the author has achieved considerable advances in tuning the redox process of lithium-rich electrodes to obtain enhanced electrochemical performance, identifying both the stability mechanism of anionic redox in lithium-rich cathode materials, and its activation mechanism in these electrode systems.
Book Synopsis High-voltage Oxide Cathodes for High-energy-density Lithium-ion Batteries by : Zehao Cui
Download or read book High-voltage Oxide Cathodes for High-energy-density Lithium-ion Batteries written by Zehao Cui and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The worldwide electrification of the automobile industry has been strongly pushing the advancement of lithium-ion batteries (LIBs) with high energy density and long service life. Since the cathode is currently the limiting electrode for energy density, safety, and cost of commercial LIBs, extensive efforts have been devoted into investigating next-generation high-performance cathode materials with high capacity and operating voltage. Among the pool of cathodes, high-nickel layered oxide cathodes, LiNixM1−xO2 (M = Co, Mn, Al, etc.; x > 0.7), are regarded as one of the most promising candidates. However, the practical viability of high-Ni cathodes is compromised by their air instability, fast structural and interfacial deteriorations during operation, poor thermal stability, and high cost. On the other hand, another promising cathode, high-voltage spinel LiNi0.5Mn1.5O4, exhibits better thermal and structural stabilities, but suffers from rapid performance degradations due to its high operating voltage of > 4.7 V vs. Li+/Li. This dissertation focuses on stabilizing the operation of high-Ni and high-voltage spinel cathodes with diverse modification strategies and advancing the understanding of the degradation mechanisms of cells with high-voltage cathodes assisted by state-of-the-art characterizations. First, the function of atomic scale zinc-doping in a high-Ni cathode LiNi0.94Co0.04Zn0.02O1.99 is investigated. The incorporation of Zn greatly mitigates the average voltage and capacity fade by ameliorating the anisotropic lattice distortion, enhancing the structural integrity, and reducing cathode-electrolyte side reactions. Moreover, Zn-doping is proved beneficial to improve the thermal stability. Second, a cobalt- and manganese-free LiNi0.93Al0.05Ti0.01Mg0.01O2 cathode is rationally designed, synthesized, and comprehensively investigated. Collectively, the use of Al, Ti, and Mg in the cathode enables a stable operation of practical full cells over 800 cycles by alleviating electrolyte decomposition reactions, transition-metal crossover, and active lithium loss. Third, single-element doped cathodes, viz., LiNi0.95Co0.05O2, LiNi0.95Mn0.05O2, and LiNi0.95Al0.05O2, along with undoped LiNiO2, are compared through a control of cutoff energy density to elucidate the role of dopants in high-Ni cathodes. Via a group of advanced analytical techniques, it is unveiled that one critical role of dopant is regulating the state-of-charge and the occurrence of H2–H3 phase transition of high-Ni cathodes, which essentially dictates the cycle stability. Finally, electrochemical modifications on the graphite anode and high-voltage spinel cathode are performed and characterized. The results suggest that the graphite anode interphase degradations caused by acidic and transition-metal crossover species generated from the cathode predominately contribute to the cell performance deterioration. Based on in-depth analyses, pathways towards long-life high-voltage full cells are pictured

Book Synopsis Understanding the Structure and Structural Degradation Mechanisms in High-voltage Lithium-ion Battery Cathode Oxides. A Review of Materials Diagnostics by :
Download or read book Understanding the Structure and Structural Degradation Mechanisms in High-voltage Lithium-ion Battery Cathode Oxides. A Review of Materials Diagnostics written by and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Materials diagnostic techniques are the principal tools used in the development of low-cost, high-performance electrodes for next-generation lithium-based energy storage technologies. Also, this review highlights the importance of materials diagnostic techniques in unraveling the structure and the structural degradation mechanisms in high-voltage, high-capacity oxides that have the potential to be implemented in high-energy-density lithium-ion batteries for transportation that can use renewable energy and is less-polluting than today. The rise in CO2 concentration in the earth's atmosphere due to the use of petroleum products in vehicles and the dramatic increase in the cost of gasoline demand the replacement of current internal combustion engines in our vehicles with environmentally friendly, carbon free systems. Therefore, vehicles powered fully/partially by electricity are being introduced into today's transportation fleet. As power requirements in all-electric vehicles become more demanding, lithium-ion battery (LiB) technology is now the potential candidate to provide higher energy density. Moreover, discovery of layered high-voltage lithium-manganese-rich (HV-LMR) oxides has provided a new direction toward developing high-energy-density LiBs because of their ability to deliver high capacity (~250 mA h/g) and to be operated at high operating voltage (~4.7 V). Unfortunately, practical use of HV-LMR electrodes is not viable because of structural changes in the host oxide during operation that can lead to fundamental and practical issues. This article provides the current understanding on the structure and structural degradation pathways in HV-LMR oxides, and manifests the importance of different materials diagnostic tools to unraveling the key mechanism(s). Furthermore, the fundamental insights reported, might become the tools to manipulate the chemical and/or structural aspects of HV-LMR oxides for low cost, high-energy-density LiB applications.

Book excerpt: This book covers both the fundamental and applied aspects of advanced Na-ion batteries (NIB) which have proven to be a potential challenger to Li-ion batteries. Both the chemistry and design of positive and negative electrode materials are examined. In NIB, the electrolyte is also a crucial part of the batteries and the recent research, showing a possible alternative to classical electrolytes – with the development of ionic liquid-based electrolytes – is also explored. Cycling performance in NIB is also strongly associated with the quality of the electrode-electrolyte interface, where electrolyte degradation takes place; thus, Na-ion Batteries details the recent achievements in furthering knowledge of this interface. Finally, as the ultimate goal is commercialization of this new electrical storage technology, the last chapters are dedicated to the industrial point of view, given by two startup companies, who developed two different NIB chemistries for complementary applications and markets.

Book Synopsis Lithium-ion Batteries by : Perla B. Balbuena
Download or read book Lithium-ion Batteries written by Perla B. Balbuena and published by World Scientific. This book was released on 2004 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Advanced High-nickel Layered Oxide Cathodes for Lithium-ion Batteries by : Wangda Li
Download or read book Advanced High-nickel Layered Oxide Cathodes for Lithium-ion Batteries written by Wangda Li and published by . This book was released on 2018 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growing demand for rechargeable Li-ion batteries with higher performance metrics has spurred intensive research efforts. In the quest for safe and low-cost cathode materials with desirable energy/power capabilities, high-nickel layered oxides (LiNi [subscript 1- x] M [subscript x] O2; x 0.5, M = Co, Mn, Al) are among the most promising candidates. However, limited cycle/calendar life especially at elevated temperatures and poor thermal-abuse tolerance are serious challenges for their practical applications. This dissertation focuses on the fundamental understanding of electrode-electrolyte incompatibility for high-Ni LiNi [subscript 1-x] M [subscript x] O2 with state-of-the-art nonaqueous electrolytes at deep charge during battery operation, and corresponding strategies for inhibiting the associated unwanted parasitic reactions and enabling excellent cyclability/safety in practical cell configurations. First, we reveal the dynamic behaviors of the CEI on LiNi [subscript 0.7] Co [subscript 0.15] Mn [subscript 0.15] O2 driven by conductive carbon in composite electrodes. Secondary-ion mass spectrometry (SIMS) shows that the CEI, initially formed on carbon black from spontaneous reactions with the electrolyte prior to cell operation, passivates the cathode through a mutual exchange of surface species. By tuning the CEI thickness, we demonstrate its impact on the evolution of the electrode-electrolyte interface during cell operation at high voltages. Next, we study the evolution of the SEI on anodes, where metallic Li deposition causes capacity fade and safety issues. On graphite harvested from pouch cells paired with LiNi [subscript 0.61] Co [subscript 0.12] Mn [subscript 0.27] O2 after 3,000 cycles, SIMS reveals large Li deposition in the SEI, triggered by transition-metal cations dissolved from the cathode and migrated to the anode. With Al doping (~1 mol %) in LiNi [subscript 0.61] Co [subscript 0.12] Mn [subscript 0.27] O2, dissolution is effectively inhibited and superior long-term cyclability is achieved ( 80% after 3,000 cycles). With knowledge on both electrodes, we then conduct a comprehensive assessment on the long-term cyclability of high-Ni LiNi [subscript 0.7] Co [subscript 0.15] Mn [subscript 0.15] O2 and commercially established LiNi [subscript 0.8] Co [subscript 0.15] Al [subscript 0.05] O2 in pouch full cells (1,500 cycles). Various degradation processes leading to performance deterioration are carefully invesitgaeted. Based on the results, we identify key challenges, relative to NCA, for realizing a long service life of high-Ni NCM and corresponding mitigation strategies. Finally, we design tailored nonaqueous electrolytes based on exclusively aprotic acyclic carbonates free of ethylene carbonate (EC) and realize unusual thermal and electrochemical performance of an ultrahigh-nickel cathode (LiNi [subscript 0.94] Co [subscript 0.06] O2), reaching a specific capacity of 235 mA h g−1. By using two model electrolyte systems, we present assembled graphite|LiNi [subscript 0.94] Co [subscript 0.06] O2 pouch full cells with exceptional thermal stability, energy/power capabilities, and long service life
