Tucker and published by . This book was released on 2014 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis focused on physicochemical and electrochemical projects directed towards two electrolyte types: 1) class of ionic liquids serving as electrolytes in the catholyte for alkali-metal ion conduction in batteries and 2) gel membrane for proton conduction in fuel cells; where overall aims were encouraged by the U.S. Department of Energy. Large-scale, sodium-ion batteries are seen as global solutions to providing undisrupted electricity from sustainable, but power-fluctuating, energy production in the near future. Foreseen ideal advantages are lower cost without sacrifice of desired high-energy densities relative to present lithium-ion and lead-acid battery systems. Na/NiCl2 (ZEBRA) and Na/S battery chemistries, suffer from high operation temperature (>300C) and safety concerns following major fires consequent of fuel mixing after cell-separator rupturing. Initial interest was utilizing low-melting organic ionic liquid, [EMI+][AlCl4-], with well-known molten salt, NaAlCl4, to create a low-to-moderate operating temperature version of ZEBRA batteries; which have been subject of prior sodium battery research spanning decades. Isothermal conductivities of these electrolytes revealed a fundamental kinetic problem arisen from "alkali cation-trapping effect" yet relived by heat-ramping>140C. Battery testing based on [EMI+][FeCl4-] with NaAlCl4 functioned exceptional (range 150-180C) at an impressive energy efficiency>96%. Newly prepared inorganic ionic liquid, [PBr4+][Al2Br7-]:NaAl2Br7, melted at 94C. NaAl2Br7 exhibited super-ionic conductivity 10-1.75 Scm-1 at 62C ensued by solid-state rotator phase transition. Also improved thermal stability when tested to 265C and less expensive chemical synthesis. [PBr4+][Al2Br7-] demonstrated remarkable, ionic decoupling in the liquid-state due to incomplete bromide-ion transfer depicted in NMR measurements. Fuel cells are electrochemical devices generating electrical energy reacting hydrogen/oxygen gases producing water vapor. Principle advantage is high-energy efficiency of up to 70% in contrast to an internal combustion engine

Download or read book Polymerized Ionic Liquids written by Ali Eftekhari and published by Royal Society of Chemistry. This book was released on 2017-09-18 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: The applications of ionic liquids can be enormously expanded by arranging the organic ions in the form of a polymer architecture. Polymerized ionic liquids (PILs), also known as poly(ionic liquid)s or polymeric ionic liquids, provide almost all features of ionic polymers plus a rare versatility in design. The mechanical properties of the solid or solid-like polymers can also be controlled by external stimuli, the basis for designing smart materials. Known for over four decades, PILs are a member of the ionic polymers family. Although the previous forms of ionic polymers have a partial ionicity, PILs are entirely composed of ions. Therefore, they offer a better flexibility for designing a responsive architecture as smart materials. Despite the terminology, PILs can be synthesized from solid organic ionic salts since the monomer liquidity is not a requirement for the polymerization process. Ionicity can also be induced to a neutral polymer by post-polymerization treatments. This is indeed an emerging field whose capabilities have been somehow overshadowed by the popularity of ionic liquids. However, recent reports in the literature have shown impressive potentials for the future. Written by leading authors, the present book provides a comprehensive overview of this exciting area, discussing various aspects of PILs and their applications as smart materials. Owing to the novelty of this area of research, the book will appeal to a broad readership including students and researchers from materials science, polymer science, chemistry, and physics.

Available in PDF, EPUB and Kindle. Book excerpt: The main motivation for the organization of the Advanced Research Workshop in Belgirate was the promotion of discussions on the most recent issues and the future perspectives in the field of Solid State lonics. The location was chosen on purpose since Belgirate was the place were twenty years ago, also then under the sponsorship of NATO, the very first international meeting on this important and interdisciplinary field took place. That meeting was named "Fast Ion Transport in Solids" and gathered virtually everybody at that time having been active in any aspect of motion of ions in solids. The original Belgirate Meeting made for the first time visible the technological potential related to the phenomenon of the fast ionic transport in solids and, accordingly, the field was given the name "Solid State lonics". This field is now expanded to cover a wide range of technologies which includes chemical sensors for environmental and process control, electrochromic windows, mirrors and displays, fuel cells, high performance rechargeable batteries for stationary applications and electrotraction, chemotronics, semiconductor ionics, water electrolysis cells for hydrogen economy and other applications. The main idea for holding an anniversary meeting was that of discussing the most recent issues and the future perspectives of Solid State lonics just twenty years after it has started at the same location on the lake Maggiore in North Italy.

Available in PDF, EPUB and Kindle. Book excerpt: "Polymer gel electrolytes, also known as ion gels, are attractive for next- generation solid-state electrolytes due to their avoidance of leakage and flammability issues related to organic solvent-based electrolytes. Ion gel electrolytes are formed by swelling polymers in ionic liquids or synthesizing ionic liquid block copolymers. Such materials can be tuned into smart materials for energy transport and storage by incorporating thermo-reversible groups. In order to impart such functionalities and to perform consistently and predictably, it is imperative for these polymers to be derived from well-defined structures. Controlled radical polymerization (CRP) techniques were employed as the synthesis method for such tailored microstructured polymers that form the core of the studies presented in this thesis.In the initial study of the novel ionic liquid block copolymers, this thesis presents the synthesis and characterization of two different poly(ionic liquid) block copolymers. Through the study of 2-acrylamido-2-methyl-1-propanesulfonate tris[2-(2-methoxy-ethoxy)ethylene] ammonium salt (AMPS-oxyethylene ammonium salt) polymer, it was aimed to synthesize well-controlled and well-defined structure AMPS oxyethylene ammonium salt polymer via two main CRP techniques, nitroxide-mediated polymerization (NMP) and reversible-addition-fragmentation chain transfer radical polymerization (RAFT), and to prove its ability as a macroinitiator to form a diblock copolymer. Unfortunately the gel permeation chromatography (GPC) molecular weight analysis in common organic solvents was not able to generate meaningful data about the molecular weight distribution. The reason and details are explained in Chapter 3. In the second study, a poly(ionic liquid) block copolymer was synthesized. First, the block copolymer poly(2-hydroxyethyl methacrylate - ran - styrene) - b - poly(styrene) (poly(HEMA-ran-S)-b-PS) was synthesized by NMP, then converted quantitatively into its corresponding poly(2-bromoethyl methacrylate - ran- styrene) - b - poly(styrene) (poly(BrEMA-ran-S)-b-PS), the precursor towards ionic liquid containing-polymer. The brominated block copolymer was subsequently functionalized with a nucleophile, 1-methylimidazole, becoming poly(1-[(2-methacryloyloxy)ethyl]-3-methylimidazolium bromide - ran - styrene) - b - poly(styrene) (poly([MEMIm][Br]-ran-S)-b-PS) block copolymer. The micro-phase separation and morphology of the poly(ionic liquid) diblock copolymer was investigated by transmission electron microscopy (TEM). The TEM image indicated weak microphase separated morphology with no long-range periodic order, shown in Chapter 4." --

This book was released on 2012 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In the present research, 1-butyl-2,3-dimethyl-4-vinylimidazolium trifluoromethane sulfonate (triflate) was synthesized and polymerized. This is the first report of the synthesis and polymerization of this ionic liquid monomer. The resulting polymer was characterized by NMR, GPC and thermal analysis (DSC and TGA). The number average molecular weight of the polymer was ~39,600 g/mol (PD=1.75). The polymer was ion-exchanged to create the trifluoromethyl sulfonylimide (TSFI) and hexafluorophosphate (PF6−) polymer derivatives. Poly(1-butyl-2,3-dimethyl-4-vinylimidazolium triflate) and poly(1-butyl-2,3-dimethyl-4-vinylimidazolium TFSI) were characterized by TGA and all the three polymers were characterized by DSC. The TGA showed that poly(1-butyl-2,3-dimethyl-4-vinylimidazolium triflate) and poly(1-butyl-2,3-dimethyl-4-vinylimidazolium TFSI) had the same decomposition temperature profiles, with mass loss beginning at 400°C and ending at 510°C. Glass transition characteristics were evaluated by DSC. Poly(1-butyl-2,3-dimethyl-4-vinylimidazolium hexafluorophosphate) exhibited the lowest onset glass transition temperature, 78°C, as compared to 94°C for poly(1-butyl-2,3-dimethyl-4-vinylimidazolium triflate) and 96°C for poly(1-butyl-2,3-dimethyl-4-vinylimidazolium TFSI)."--Abstract.
