Book excerpt: With ever-increasing energy demands, tremendous efforts have been devoted to developing rechargeable batteries. Conventional lithium-ion batteries have been widely used for decades, but are approaching their theoretical limit and are unable to meet the rising energy demands. Lithium–sulfur (Li–S) batteries are being actively pursued owing to their high energy density and cost-effectiveness. However, the commercial implementation of Li–S batteries has been impeded by the challenges associated with the sulfur cathodes, including extremely low conductivity, large volumetric expansion and rapid capacity loss arising from the dissolution of the intermediates, and the Li anode, owing to the uncontrollable formation of Li dendrites. To fulfill the promise of Li–S batteries as high-energy devices, it is necessary to solve these issues. In this dissertation, effective materials as sulfur hosts have been studied and possible strategies to improve the performance of the sulfur cathode proposed. These involve designing the structure of the host material to efficiently accommodate sulfur and, at the same time, applying the strong adsorption properties between the active material and the host. As to the Li anode, approaches to suppress the growth of Li dendrites were demonstrated by coating the surface of the anode current collector. These strategies were successful in inhibiting Li dendrites and significantly improve the performance of Li anodes. These studies provide promising results for high-performance Li–S batteries for future large-scale applications.

Book Synopsis Synthesis and Electrochemical Characterization of Novel Electroactive Materials for Lithium-ion Batteries by : Karl Joseph Kreder (III)
Download or read book Synthesis and Electrochemical Characterization of Novel Electroactive Materials for Lithium-ion Batteries written by Karl Joseph Kreder (III) and published by . This book was released on 2017 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lithium-ion batteries (LIBs) have become ubiquitous as energy storage devices for mobile electronics, electric vehicles, and are beginning to be used for electric grid-scale energy storage. Lithium-ion batteries offer higher efficiencies, energy density, and longer life compared to incumbent technologies such as lead-acid and nickel metal hydride. Applications in which LIBs are used are continuing to demand better performing batteries at lower cost, which requires improvement in electroactive materials. This dissertation investigates the low temperature synthesis and modification of LiCoPO4 as a potential high-voltage and therefore higher energy density polyanion cathode material for LIBs, as well as a new class of interdigitated metal foil anodes which promises to be an inexpensive, higher energy density, alternative to graphite. Chapter 1 is a brief introduction to lithium-ion batteries and the principle of operation of intercalation type electrochemical energy storage devices. The components of lithium ion batteries are introduced, specifically the anode, cathode, separator, and electrolyte. Some of the shortfalls of the current technologies are discussed and areas of research interest are highlighted. Chapter 2 is a brief overview of the various experimental methods that are generally applicable to more than one of the subsequent chapters. Methods which are specific to a given study are discussed in their respective chapters. Chapter 3 presents work on the low temperature microwave-assisted solovthermal synthesis (MW-ST) of three unique polymorphs of LiCoPO4, specifically the polymorphs belonging to the Pnma, Cmcm, and Pn21a space groups. Prior to this work, only the Pnma polymorph had been reported via MW-ST method, and electrochemistry had not yet been reported for either the Pn21a or Cmcm polymorph. The dependence of the polymorphs on both the water content, and ammonium hydroxide content of the solvent was shown. Although, the electrochemistry of both the Pn21a and Cmcm polymorphs was found to be inferior to the Pnma polymorph, the ability to synthesize phase pure materials was crucial to conducting the work presented in chapters 4 and 5. Chapter 4 presents the aliovalent substitution of V3+ for Co2+ in LiCoPO4 via a low-temperature MW-ST process. Substitution of up to 7% vanadium for cobalt was demonstrated and verified by changes in the lattice parameters with vanadium content. Both the ionic and electronic conductivity of LiCoPO4 was enhanced with increasing vanadium substitution, which was attributed to the introduction of both charge carriers as well as inter-tunnel cobalt vacancies. Finally, the first cycle capacity was enhanced (from 69 mAh/g to 115 mAh/g) as well as the capacity retention over cycling. Chapter 5 demonstrates a novel technique of MW-ST assisted coating of a thin (2-5nm) conformal coating of LiFePO4 on vanadium substituted LiCoPO4. Although the vanadium substitution was able to independently increase the performance of LiCoPO4, the materials still suffers from severe side reactions with the electrolyte. The coating of LiFePO4 effectively raises the Fermi energy of the cathode material above the high occupied molecular orbital (HOMO) of the electrolyte preventing side reactions and increase the coulombic efficiency to nearly 100%. Chapter 6 introduces a novel method of producing high surface area, electrically conductive, metal nanofoams via a MW-ST process. Nickel, copper, and silver metal nanofoams are made via an inexpensive yet scalable process whereby metal acetates are reduced by polyglycol under microwave irradiation. The nanofoams were characterized via BET, SEM, XRD, EDS, and TEM. The nanofoams have potential uses in many clean energy applications, particularly lithium-ion batteries. Chapter 7 introduces a new framework for making a new class of high capacity, low-cost alloying anodes for lithium ion batteries. A novel interdigitated metal foil anode (IMFA) in which a nanosized active material, such as tin, is interdigitated with an electrically conductive matrix, such as aluminum, is presented. The foils are formed by the rolling of a eutectic Al-Sn alloy into a foil, which is an extremely cheap and scalable process. The anodes demonstrate an approximately 70% increase in capacity compared to graphite over 100 cycles, at reasonably fast rates (C/5), and high coulombic efficiency (>99%). Finally, Chapter 8 gives a brief overview of the results of the prior work and proposes areas for future research

This book was released on 2015 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developing new cathode materials is key to improving the energy density of rechargeable batteries and enabling new applications of energy storage. In this thesis, two families of materials were explored as candidate cathode materials: the dirutile and rutile polymorphs of LiMnF4, and layered lithium-excess . . . Dirutile LiMnF4 was identified from high-throughput computation as a promising conversion cathode. The dirutile polymorph was synthesized through a new low temperature route, and the rutile polymorph was discovered upon mechanical milling. With simple synthesis and electrode preparation methods, both dirutile and rutile polymorphs of LiMnF4 showed electrochemical activity. Electron diffraction confirmed both polymorphs to convert upon lithiation along different reaction paths. As with other fluorides, specific capacity was strongly linked with processing conditions. The layered lithium-excess . . . compounds were designed from recent understanding of diffusion channels in lithium-excess materials. Increasing lithium content was found to improve both discharge capacity and capacity retention. Structural studies revealed a complex nanostructure pattern of Li-Sb and Ni-Sb ordering where the interface between these domains formed the correct local configuration for good lithium mobility. The

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.
