This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrolytes with high ionic conductivity, lithium transference numbers, and sufficient mechanical strength are desired for application in lithium-ion battery technologies. Nanoparticle-based electrolytes, in which nanoparticles are embedded in ion-conducting solid polymers or liquids, have recently emerged as a relatively novel yet promising class of electrolyte material for next-generation lithium ion batteries. However, the relatively modest ionic conductivities exhibited by these materials continues to be a bottleneck for their commercialization. To understand and improve upon the ionic conductivities exhibited by nanoparticle-based electrolytes, we employed multiscale simulation approach to identify the mechanisms underlying the experimentally observed conductivity characteristics and identify the key design parameters. Our results in this regard suggest that for some classes of experimental systems reported thus far, the dominant pathway for cation transport is along the surface of nanoparticles, in the vicinity of nanoparticle-tethered anions. On tuning the key design parameters and analyzing the previously unexplored design space, our results suggest the dielectric constant of the medium to be a key design parameter for achieving elevated conductivity. Since the dominant transport of cations was elucidated to be along the surface of the nanoparticles, we expect certain nanoparticle microstructures to exhibit better conductivities than others. In this context, we demonstrate that some morphologies can simultaneously exhibit enhanced ion transport and elevated mechanical properties, thus illustrating the potential of nanoparticle-based electrolytes to decouple ion transport and mechanical strength generally observed in polymer electrolytes. Further, to overcome the computational cost issues accompanying the conventional multiscale simulation approach to probe the ionic conductivity, we developed a machine learning-based model to quantitatively link the ionic conductivity to the spatial arrangement of the nanoparticles. Such an approach allows for faster yet fairly accurate prediction of the ionic conductivities. By integrating the trained model with a nanoparticle topology optimization algorithm, we demonstrate accelerated search of morphological space to identify nanoparticle networks exhibiting a wide range of ionic conductivities. As a first step towards design of copolymer electrolytes intended for functionalization of nanoparticles, we also investigate ion transport in single lithium-ion conducting, comb-branched copolymer electrolytes synthesized by experimental collaborators. Our simulations reveal the degree of decoupling of ionic conductivity from polymer dynamics to be significantly influenced by the composition of the copolymer and the choice of the anion, thus suggesting strategies to improve ionic conductivity of single-ion conducting polymer electrolytes without negatively impacting their mechanical strength

Download or read book Applications of Electroactive Polymers written by Bruno Scrosati and published by Springer Science & Business Media. This book was released on 1993-05-31 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electroactive polymers have been the object of increasing academic and industrial interest and in the past ten to fifteen years substantial progress has been achieved in the development and the characterization of this important new class of conducting materials. These materials are usually classified in two large groups, according to the mode of their electric transport. One group includes polymers having transport almost exclusively of the ionic type and they are often called 'polymer electrolytes' or, in a broader way, 'polymer ionics'. The other group includes polymeric materials where the transport mechanism is mainly electronic in nature and which are commonly termed 'conducting polymers'. Ionically conducting polymers or polymer ionics may be typically described as polar macromolecular solids in which one or more of a wide range of salts has been dissolved. The most classic example is the combina tion of poly(ethylene oxide), PEO, and lithium salts, LiX. These PEO-LiX polymer ionics were first described and proposed for applications just over ten years ago. The practical relevance of these new materials was im mediately recognized and in the course of a few years the field expanded tremendously with the involvement of many academic and industrial lab oratories. Following this diversified research activity, the ionic transport mechanism in polymer ionics was soon established and this has led to the development of new host polymers of various types, new salts and advanced polymer architectures which have enabled room temperature conductivity to be raised by several orders of magnitude.

Download or read book Understanding and Engineering Ion Transport in Conducting Polymers written by Eleni Stavrinidou and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many organic electronic and bioelectronics devices rely on mixed (electronic and ionic) transport within a single organic layer. Although electronic transport in these materials is relatively well understood, a fundamental understanding of ion transport is missing. I developed a simple analytical model that describes ion transport in a planar junction between an electrolyte and a conducting polymer film. The model leads to predictions of the temporal evolution of drift length of ions and current. These predictions are validated by numerical simulations and by using realistic parameters, I show that the analytical model can be used to obtain the ion mobility in the film. Furthermore, I developed an experimental method which allows the application of the analytical model and leads to a straightforward estimation of the ion drift mobilities in conducting polymers. PEDOT:PSS was found to support efficient transport of common ions, consistent with extensive swelling of the film in water. Crosslinking the film decreased its swelling and the ion mobility. Understanding the high correlation of hydration and ionic conductivity enables us to engineer materials with high and defined ion mobilities. As an example tuning of ion mobility by adjusting the relative ratio of the hydroscopic phase to PEDOT:TOS is presented. Finally I performed electrochemical impedance spectroscopy during a moving front experiment, in order to give a physical interpretation of the impedance spectra at a conducting polymer/electrolyte junction.

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.
