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 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Rechargeable lithium ion batteries are revolutionary energy storage systems widely used in portable electronic devices (e.g., mobile phones, laptops) and more recently electrical vehicles. The conventional liquid electrolytes in the lithium ion battery brought about safety problems such as fire and explosion. Related safety accidents (e.g., cell phone explosion, laptop fire, plane smoldering, etc.) have been reported many times. This also eliminates the possibility of using lithium metal as anode material which has much higher theoretical specific capacity in comparison with commercial graphite electrode because of the growth of uncontrolled lithium dendrites can lead to short circuit and other serious accidents. Solid polymer electrolytes have many advantages over conventional liquid electrolytes. They are light-weighted, non-volatile and have much better safety features than liquid electrolyte. Meanwhile, they are also better than the ceramic electrolyte in terms of their excellent flexibility and processability. Currently, low ionic conductivity of solid polymer electrolytes (e.g., polyethylene oxide (PEO)) at ambient temperature still hinders their practical application. Ionic liquids (ILs) are non-flammable and have negligible volatility. Its ionic conductive nature, excellent chemical stability, and good electrochemical stability enable them to be regarded as useful components for next generation battery electrolytes. In this thesis work, focus will be placed on synthesis and characterization of ionic liquid tethered organic/inorganic hybrid polymer electrolyte with high room temperature ionic conductivity. Moreover, their electrochemical properties and prototype battery performances were also looked into. The use of highly conductive solid-state electrolytes to replace conventional liquid organic electrolytes enables radical improvements in reliability, safety and performance of lithium batteries. Here in chapter 2, we report the synthesis and characterization of a new class of nonflammable solid electrolytes based on the grafting of ionic liquids onto octa-silsesquioxane. The electrolyte exhibits outstanding room-temperature ionic conductivity (~4.8 10-4 S/cm), excellent electrochemical stability (up to 5 V relative to Li+/Li) and high thermal stability. All-solid-state Li metal batteries using the prepared electrolyte membrane are successfully cycled with high coulombic efficiencies at ambient temperature. Good cycling stability of the electrolyte against lithium has been demonstrated. This work provides a new platform of solid polymer electrolyte for the application of room-temperature lithium batteries. In chapter 3, an organic-inorganic hybrid solid electrolyte with ionic liquid moieties tethered onto dumbbell-shaped octasilsesquioxanes through oligo(ethylene glycol) spacers was synthesized. The hybrid electrolyte is featured by its high room-temperature ionic conductivity (1.210-4 S/cm at 20 oC with LiTFSI salt), excellent electrochemical stability (4.6 V vs Li+/Li), and great thermal stability. Excellent capability of the hybrid electrolyte to mediate electrochemical deposition and dissolution of lithium has been demonstrated in the symmetrical lithium cells. No short circuit has been observed after more than 500 hrs in the polarization tests. Decent charge/discharge performance has been obtained in the prepared electrolyte based all-solid-state lithium battery cells at ambient temperature. In chapter 4, hybrid polymer electrolyte network (XPOSS-IL) synthesized by crosslinking the individual dendritic POSS-IL was investigated. To be specific, after grafting mono-broninated hexaethylene glycol to the POSS cage, 1-vinyl imidazole was adopted for the subsequent quarternization reaction. Then the chain end double bonds underwent free radical crosslinking process to produce XPOSS-IL. The ionic conductivity of LiTFSI dissolved XPOSS-IL is 5.4 10-5 S/cm at 30 . By adding a small fraction of ionic liquid 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMITFSI), the ionic conductivity increases to 1.4 10-4 S/cm at room temperature. It is also found that EMITFSI will enhance the anodic stability of XPOSS-IL. The Li/LTO and Li/LFP cell assembled with X-POSS-IL-LiTFSI/EMITFSI demonstrates capability of delivering high specific capacities at room temperature and elevated temperature.

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.

This book was released on 2006 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lithium ion batteries deliver the highest specific energy and energy density of commercially available secondary batteries. The objective of this study was to evaluate lithium-manganese phosphate (LiMnPO4) for potential application as a cathode material in lithium ion batteries due to its high theoretical capacity and stable phospho-olivine structure. LiMnPO 4 was successfully synthesized via a novel aqueous sol-gel process under an inert nitrogen and air atmosphere. Microstructural design strategies including annealing treatment and the addition of 1 wt% copper dopant were evaluated in order to improve the electrochemical performance of the LiMnPO4 cathode. The cathode particle microstructure and morphology were characterized using X-ray diffraction and scanning electron microscopy. Open circuit voltage was 4.1 V for all samples. The electrochemical performance of LiMnPO 4 is significantly improved by the addition of a dopant in an inert nitrogen atmosphere with a specific capacity of 28 mAh/g achieved during the first discharge cycle.
