Download or read book Modeling Ion Mobility in Solid-state Polymer Electrolytes written by Songela Wenqian Chen and published by . This book was released on 2019 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: We introduce a course-grained model of ion diffusion in a solid-state polymer electrolyte. Among many tunable parameters, we investigate the effect of ion concentration, ion-polymer attraction, and polymer disorder on cation diffusion. For the conditions tested, we find that ion concentration has little effect on diffusion. Polymer disorder creates local variation in behavior, which we call "trapping" (low diffusion) and "free diffusing" (high diffusion) regions. Changing ion-polymer attraction modulates the relative importance of trapping and free diffusing behavior. Using this model, we can continue to investigate how a number of factors affect cation diffusion both mechanistically and numerically, with the end goal of enabling rapid computational material design.

Book Synopsis Study of lithium deposition and applicability of solid polymer electrolytes in lithium cells (Band 10) by : Sanaz Momeni Boroujeni
Download or read book Study of lithium deposition and applicability of solid polymer electrolytes in lithium cells (Band 10) written by Sanaz Momeni Boroujeni and published by Cuvillier Verlag. This book was released on 2022-12-30 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lithium (Li) deposition is a problem in Li batteries (LB) – both Li metal (LMB) and Li-ion (LIB) batteries – which limits their performance in terms of power and energy density. Two trends can be identified in the advancement of LBs concerning the problem of Li deposition: optimization of the existing system (the state-of-the-art LIBs) and further development of cell components such as electrolytes. This work addresses both approaches. In the first part, this study investigates Li deposition in LMB and LIBs. A novel method to study the Li-based transport mechanisms in LIBs is introduced. Later the kinetic deviations between anode and cathode as a consequence of aging and the relation of these deviations to the occurrence of Li-plating are discussed. In the second part, the applicability of PEO-based solid polymer electrolytes for LMBs to overcome the Li plating issue is investigated. The introduction of various interfacial interlayers at the cathode/electrolyte interphase was studied to improve the electrochemical stability of the cells. Cells with an in-situ electro-deposited interlayer showed the best cyclability.
Book Synopsis Perfluorinated Polymer Electrolyte Membranes for Fuel Cells by : Tatsuhiro Okada
Download or read book Perfluorinated Polymer Electrolyte Membranes for Fuel Cells written by Tatsuhiro Okada and published by Nova Science Pub Incorporated. This book was released on 2008 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book the authors focus on the ion and water transport characteristics in Nafion and other perfluorinated ionomer membranes that are recently attracting attention in various fields such as water electrolysis, mineral recovery, electrochemical devises and energy conversion. Methodology of measurements and data analysis is first presented that enables basic characterisation of transport parameters in the perfluorinated ionomer membranes. Cation exchange isotherm data are collected in binary cation systems, with the aim to see the behaviours of cationic species that exist with H+ in the membrane. Water transference coefficients, ionic transference numbers, ionic mobilities and other membrane transport parameters are measured in single and mixed counter cation systems using electrochemical methods. Diffusion coefficients of water and cations are also measured by pulsed-field-gradient spin-echo NMR (PGSE-NMR) at various temperatures in different kinds of perfluorinated ionomer membranes. The results are discussed in two perspectives. One is to predict the hydration state in perfluorosulfonated ionomer membranes in relation to the possible degradation of performances in fuel cells under contaminated conditions with foreign cations. An analytical formulation of membrane transport equations with proper boundary conditions is proposed, and using various parameters of membrane transport, a simple diagnosis of water dehydration problem is carried out. This analysis leads one to an effective control of fuel cell operation conditions, especially from viewpoint of proper water management. The others are to elucidate the ion and water transport mechanisms in the membrane in relation to polymer structures (e.g., different ion exchange capacity), and to propose a new design concept of polymer electrolyte membranes for fuel cell applications. Additionally for this purpose methanol and other alcohols are penetrated into the membrane, and alcohol permeability, membrane swelling, ionic conductivity and diffusion coefficients of water and CH3 are measured systematically for various kinds of membranes to cope with the problem of methanol crossover in direct methanol fuel cells (DMFCs).It is found that in order to realise a high ionic conductivity in the membrane, one should aim at a polymer structure through molecular design that takes into account the relative size of ions with a hydration shell against the size and atmosphere of ionic channels. For DMFC, a partially cross-linked polymer chain with high degree of hydrophilic ion transport paths based on phase-separated structures is recommended. Various possibilities of such polymer electrolytes are discussed.
