Book excerpt: The limited worldwide Cobalt resource has spurred demand for new cathode materials with reduced Cobalt reliance. Substituting Cobalt with Nickel giving high-Nickel cathode material is a promising solution due to its high energy density and cheaper price. However, the poor cycling stability of high-nickel cathode materials is the major challenge that hinders their widespread adoption in electric vehicles and other energy storage applications. This work reports a significant advance in the development of high-nickel cathode materials with improved cycling stability. Firstly, a scalable synthesis route is developed to produce high-nickel cathodes with favorable morphology and high nickel content of 92%. Various low-cost doping elements including Mg, Al and Ti are screened to improve the structure of high-nickel cathodes during cycling. A Dual Protective strategy with AlPO4 nanoparticles as a representative is introduced as a low cost and effective approach to prolong the cycle stability of high-nickel cathodes. Finally, single-crystalline high-nickel cathodes are synthesized, and their electrochemical performance is compared with polycrystalline cathodes. The synthesized high-nickel cathode materials exhibit excellent electrochemical performance and significantly improved cycling stability. This work demonstrates promising pathways towards the commercialization of high-nickel cathode materials for Lithium Ion Batteries.

This book was released on 2015 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Renewable energy sources such as solar energy, wind and hydroelectric power are increasingly being developed as essential energy alternatives to alleviate the deleterious effects of greenhouse gases in the globe. Large scale energy storage is an indispensable component of renewable energy sources and in this context, Li-ion batteries (LIBs), due to their high energy and power densities and long cycle life, have spurred great interest. Current Li-ion battery technology employs lithium cobalt oxide, LiCoO2, or one of its congeners, in which some of the Co is substituted with Ni and/or Mn as cathode active material. The deficiencies of LiCoO2 include: i-) low capacity with only 0.5 mole of Li+ is being reversibly used in the battery leading to 140 mAh/g discharge capacity at low to medium rates, ii-) high cost, and iii-) environmental concerns arising from the harmful physiological effects of Co metal. In order to overcome these deficiencies of LiCoO2, Li-rich layered metal dioxides, also known as layered-layered lithiated metal oxide composite compound, formulated as xLi2MnO3.(1-x)LiMO2 (M=Mn, Ni or Co), have been proposed recently. This dissertation presents an account of investigations leading to advanced materials which overcome the deficiencies of this class of high energy density Li-ion battery cathodes. Chapter 1 discusses the fundamental aspects of generic battery systems and elaborates on the current state of the art of rechargeable Li batteries. Chapter 2 deals with the discovery of the material 0.3Li2MnO3.0.7LiNi0.5Co0.5O2 (LLNC) that allowed us to conclude which segment of the lithium rich layered composite metal oxide is responsible for structural transformation from the layered to spinel phase during charge/discharge cycling. The crystal structure and electrochemistry of this new cathode active material in Li cells have been compared to that of 0.3Li2MnO3.0.7LiMn0.33Ni0.33Co0.33O2 (LLNMC). In LLNC, the removal of Mn from the LiMO2 (M=transition metal) segment allowed us to determine the identity of the manganese oxide moiety in it that triggers the layered to spinel conversion during cycling. The new material LLNC resists the layered to spinel structural transformation under conditions in which LLNMC does. X-ray diffraction (XRD) patterns revealed that both compounds, synthesized as approximately 300 nm crystals, have identical super lattice ordering attributed to Li2MnO3 existence. Using X-ray absorption (XAS) spectroscopy we elucidated the oxidation states of the K edges of Ni and Mn in the two materials with respect to different charge and discharge states. The XAS data along with electrochemical results revealed that Mn atoms are not present in the LiMO2 structural segment in LLNC. Electrochemical cycling data from Li cells further revealed that the absence of Mn in the LiMO2 segment significantly improves the rate capabilities of LLNC with good capacity maintenance during long term cycling. Removing the Mn from the LiMO2 segment of lithium rich layered metal oxides appears to be a holistic strategy for improving the structural robustness and rate capabilities of these high capacity cathode materials for Li-ion batteries. Chapter 3 examines the effect of alkali ion doping (Na+) into the cathode material of the composition 0.3Li2MnO3.0.7LiMn0.33Ni0.33Co0.33O2 (LLNMC). The 5 wt. % Na doped material, formulated as 0.3Li2MnO3.0.7Li0.97Na0.03Mn0.33Ni0.33Co0.33O2, was compared to its counterpart without Na doping. The discharge rate capability of the LLNMC was greatly improved at both room temperature and 50 0C with the Na doping. The Na doped material exhibited significantly higher electronic conductivity than its un-doped analog as evidenced by dc electronic conductivity data and AC impedance of Li cells. Charge/discharge cycling results of Li cells containing these cathode materials at 50 0C indicated that the voltage decay of LLNMC, accompanied by a layer to spinel structural conversion, was mitigated with Na doping. X-ray diffraction analysis revealed that ionic exchange of Na occurs upon contact of the cathode material with the electrolyte and produces a volume expansion of the crystal lattice which triggers a favorable metal (probably Ni) migration to Li depleted regions during electrochemical oxidation of Li2MnO3 in the first charge. X-ray absorption near edge spectra (XANES) data showed that Na doped NMC has better Ni reduction efficiency to provide higher rate capability. Extended X-ray absorption fine spectra (EXAFS) data supported this conclusion by showing that in the case of Na doped LLNMC, the structure has a larger crystal cage allowing for better metal migration into the Li depleted regions located in the layered unit cell of C2/m space group. XANES of Mn K-edge supported by pre-edge analysis also revealed that during charging of the electrode, the Na doped NMC was oxidized to a higher Mn valence state compared to its undoped counterpart. The results of a comprehensive electrochemical and structural investigations of a wide range of lithium rich layered metal oxide cathode active materials, xLi2MnO3.(1-x)LiMnaNibCocO2 (where x, a, b and c vary) are reported in Chapter 4. In order to identify the cathode material having the optimum Li cell performance we first varied the ratio between Li2MnO3 and LiMO2 segments of the composite oxides while maintaining the same metal ratio residing within their LiMO2 segments. The materials with the overall composition 0.5Li2MnO3.0.5LiMO2 containing 0.5 mole of Li2MnO3 per mole of the composite metal oxide were found to be the optimum in terms of electrochemical performance. The electrochemical properties of these materials were further tuned by changing the relative amounts of Mn, Ni and Co in the LiMO2 segment to produce xLi2MnO3.(1-x)LiMn0.50Ni0.35Co0.15O2 with enhanced capacities and rate capabilities. The rate capability of the lithium rich compound in which x=0.3 was further increased by preparing electrodes with about 2 weight-percent multiwall carbon nanotube in the electrode. Lithium cells prepared with such electrodes were cycled at the 4C rate with little fade in capacity for over one hundred cycles. In Chapter 5, the results of a new synthesis technique, called self-ignition combustion (SIC), that dramatically enhanced the rate capabilities of a lithium rich layered metal oxide compound we prepared are discussed. In this chapter, we report a high rate Li-rich layered manganese nickel cobalt (MNC) cathode material of the composition 0.5Li2MnO3.0.5LiMn0.5Ni0.35Co 0.15O2, termed SIC-MNC cathode material for Li-ion batteries with discharge capacities of 200, 250, and 290 mAh/g at C, C/4 and C/20 rates, respectively. This high rate discharge performance combined with little capacity fade during long term cycling is unprecedented for this class of Li-ion cathode materials. The exceptional electrochemistry of the Li-rich SIC-MNC in Li-ion cells is attributed to its open porous morphology and high electronic conductivity. The structure of the material investigated by means of X-ray diffraction, High Resolution Transmission Electron Microscopy (HRTEM) and X-ray absorption spectroscopy combined with electrochemical data revealed that the porous morphology was effective in allowing electrolyte penetration through the particle grains to provide high Li+ transport in tandem with high electronic conductivity for high rate discharge. Extended cycling behavior and structural phase transition of the new material were further examined through Field Emission Scanning Electron Microscopy (FESEM), XRD, XAS and HRTEM. The new SIC-MNC cathode represents the long sought after next generation cathode material for Li-ion batteries with pecific energy exceeding 400 Wh/kg or energy density over 1000 Wh/l. The conclusion and future directions are presented in Chapter 6.

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

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.

This book was released on 2009 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today, the Lithium ion (Li-ion) is the fastest growing and most promising rechargeable battery chemistry. For high current demands, there is an emphasis on the importance of very low cell resistance to allow unrestricted flow of current. The electrochemical performance of Li-ion batteries relies significantly on the properties of the cathode materials, the anode materials and the electrolytes. In this study, novel anode and cathode materials were synthesized and systematically studied for Li-ion battery application. Novel anode synthesis involved the substitution of the flat foil current collectors normally used by nano- or micro-wire arrays, as the higher surface area makes it possible to pack much more active material into an electrode. Ni or Cu wire arrays with wire thicknesses of 200 nm, 400 nm or 1 \03BCm were synthesised. Carbon nanotubes (CNTs) were chosen as the Li-insertion compound due to its high theoretical reversible lithium storage capacity. Synthesis of the Cu or Ni/CNT consolidated composite anodes were done using novel synthetic techniques, combining template synthesis via electrochemical deposition and chemical vapour deposition (CVD) techniques. XRD analysis of both the Ni and Cu wire arrays after carbon nanotube deposition, confirmed that the crystallinity of the wire arrays were not altered by the CVD of carbon nanotubes. The optimal results were obtained for the 200 nm Cu/CNT consolidated composite anode. The current density obtained for the Li de-intercalation (\03AFp) was 0.463 A/g. A reversible discharge capacity of 358 mAh/g was obtained in the subsequent charge/discharge cycling. The composite anode materials showed good charge/discharge cycling performances and a high capacity integrity was maintained in the cycling behaviour analyses.
