Book Fusible Alloy Electrodes and Multi cation Interfacial Chemistry in Alkali Metal Batteries

Download or read book Fusible Alloy Electrodes and Multi cation Interfacial Chemistry in Alkali Metal Batteries written by Xuelin Guo and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing need of portable and efficient energy storage technologies that delivers higher energy and higher power density became one of the most urgent tasks in this century. Lithium metal as one of the most promising anode materials for Li-ion batteries have severe intrinsic limitations, such as dendritic issue and interfacial contact issue, which could seriously degrade the battery performance and cause safety concerns. Therefore, to further push the energy storage capability of the next-generation batteries to a higher level, researchers dedicate their efforts to look for more suitable alternative anode materials and to gain deeper understanding for more efficient battery designs. The fusible alloys that have low melting-temperature close to or lower than room-temperature can be ideal replacements of Li metal to avoid dendrite formation while maintaining superior cyclability and high energy density. Fusible alloys, especially liquid Na-K alloy, have more benefits for being more abundant and both species can carry the charge. The low reduction potentials comparable to Li for both K and Na also help to boost the Na-K alloy energy density to be even higher. The capability of electronic conductivity as well as deformability further allows their applications in solid-state batteries, which have been suffering from poor interfacial charge transport and even more severe dendrite issues than using liquid electrolytes. Solid-state electrolytes being compatible with the alkali metal anodes could ideally deliver significantly enlarged energy and power density of an alkali-ion battery. The debate on battery interfacial chemistry have lasted for many years, and with current technologies, the electrode-electrolyte interfaces have not yet been completely understood. Whereas with the multi-cation system, the interfacial decomposition processes could be more clearly revealed. Due to the special wetting behavior and complicated multi-cation electrochemistry, the interfacial behavior of liquid metals is both more manipulatable and more unique than single-species systems. With understanding of fusible alloy mechanical, chemical, electrical, and electrochemical properties, the designs for higher stability and energy-density with self-healing, dendrite-free, hybrid-ion, flexible, and fluidic properties, as well as mechanism studies of the wettability, interfacial stability, and charge selection properties were carried out

Book Computational Design of Novel Electrodes for Alkali ion Batteries

Download or read book Computational Design of Novel Electrodes for Alkali ion Batteries written by Xingyu Guo and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The alkali-ion batteries are the key to unlock the bottleneck of the renewable energy storage and pave the way for a renewable-powered future. Battery technologies for grid-scale energy storage systems requires low costs, safety, high efficiency and high sustainability. In this dissertation, we present not only in-depth understandings of the electrode working mechanism but also develop novel cathode materials for alkali-ion batteries using first principles calculations. We divide the dissertation into four project-based parts. In the first project, we performed a comprehensive study of Prussian blue and its analogues (PBAs) cathodes in aqueous sodium-ion batteries. Using density functional theory calculations, we proposed a general rule of the phase transition that dry PBAs generally undergo a phase transition from a rhombohedral Na2PR(CN)6 (where P and R are transition metals) to a tetragonal/cubic PR(CN)6 during Na extraction, which is in line with experimental observations. Using a grand potential phase diagram construction, we show that existence of lattice water and Na co-intercalation contribute to both higher energy density and better cycling stability. We also identified four new PBA compositions {Na2CoMn(CN)6, Na2NiMn(CN)6, Na2CuMn(CN)6 and Na2ZnMn(CN)6--that show great promise as cathodes for aqueous rechargeable Na-ion batteries. In the second project, we developed design rules for aqueous sodium-ion battery cathodes through a comprehensive density functional theory study of the working potential and aqueous stability of known cathode materials. These design rules were applied in a high-throughput screening of Na-ion battery cathode materials for application in aqueous electrolytes. Five promising cathode materials--NASICON-Na3Fe2(PO4)3, Na2FePO4F, Na3FeCO3PO4, alluadite-Na2Fe3(PO4)3 and Na3MnCO3PO4, were identified as hitherto unexplored aqueous sodium-ion battery cathodes, with high voltage, good capacity, high stability in aqueous environments and facile Na-ion migration. These findings pave the way the practical cathode development for large-scale energy storage systems based on aqueous Na-ion battery chemistry. Then in the third project, we constructed a large database of aqueous Na-ion battery cathodes (Na-ion Aqueous Electrode Database, or NAED) based on the developed design rules in the second project. By screening and analyze the data in the database, we identified two promising candidates, NaMn2O4 and Na2(FeVO4)3 for synthesis and experimentation in aqueous sodium-ion batteries. The final project presents a comprehensive study of Li insertion mechanism in DRX-Li3V2O5 anode in Li-ion batteries. Using a combination of first-principles calculations, cluster expansion and machine learning methods, we show that during discharge, Li ions mainly intercalate into tetrahedral sites, while the majority of Li and V ions in octahedral sites remain stable. Furthermore, its fast-charging nature is attributed to the facile diffusivity of Li ions via a correlated "octahedral-tetrahedral-octahedral" Li diffusion.

Book High Energy Density Cathode Active Materials for Lithium ion Batteries

Download or read book High Energy Density Cathode Active Materials for Lithium ion Batteries written by Mehmet Nurullah Ates and published by . 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.

Book New Promising Electrochemical Systems for Rechargeable Batteries

Download or read book New Promising Electrochemical Systems for Rechargeable Batteries written by V. Barsukov and published by Springer Science & Business Media. This book was released on 1996-02-29 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electricity is the most important secondary energy source, the present production rate, mainly from thermal electric power stations, being of the order of 1.3 TW. However, the total capacity of primary and rechargeable batteries currently in use is the same as the output of the world's power stations. But present battery systems will not meet future needs for the economical storage of large amounts of electrical energy for vehicles, public transport, road levelling, solar energy utilisation, civil video and audio, terrestrial and space communications, etc. Current accumulators based on aqueous acid or alkali systems do not have sufficient output and, moreover, the materials employed (Pb, Cd, Ni) are environmental pollutants that require safe recycling. Further, stocks of these strategic metals are being rapidly depleted. This book discusses actual field results with novel systems, such as rechargeable lithium batteries, zinc/air cells, metal-free accumulators, graphite/carbon devices and others, including fuel cells. The book stresses that a universal electrochemical system is not feasible: the choice of any system must depend on the concrete field of application and must be taken in consideration of a large number of technical, economic and environmental circumstances.
