Download or read book On the Electro Chemo Mechanical Coupling in Solid State Batteries and its Impact on Morphological Interface Stability written by Ganser, Markus and published by KIT Scientific Publishing. This book was released on 2021-03-09 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solid state batteries with a lithium metal electrode are considered the next generation of high energy battery technology. Unfortunately, lithium metal is prone to harmful protrusion or dendrite growth which causes dangerous cell failure. Within this work the problem of protrusion growth is tackled by deriving a novel electro-chemo-mechanical theory tailored for binary solid state batteries which is then used to discuss the impact of mechanics on interface stability by numerical studies.

To investigate the influence of cathode structures on the performance of the whole cell, efficient tools for calculating effective transport properties of granular systems are developed and their influence on the electrochemical performance is investigated in specially adapted cell models.
Download or read book Multiscale Modeling of Curing and Crack Propagation in Fiber Reinforced Thermosets written by Schöller, Lukas and published by KIT Scientific Publishing. This book was released on 2024-03-15 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the production of fiber-reinforced thermosets, the resin material undergoes a reaction that can lead to damage. A two-stage polymerization reaction is modeled using molecular dynamics and evaluations of the system including a fiber surface are performed. In addition, a phase-field model for crack propagation in heterogeneous systems is derived. This model is able to predict crack growth where established models fail. Finally, the model is used to predict crack formation during curing.
Download or read book Consequences of hydroxyl generation by the silica water reaction Part I Diffusion and Swelling written by Fett, Theo and published by KIT Scientific Publishing. This book was released on 2022-07-11 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water diffusing into silica surfaces gives rise for several effectson diffusion behaviour and mechanical properties. Water added to silica glass increases its specific volume so that the silica expands near the surface. Mechanical boundary conditions give rise for compressive “swelling stresses”. This fact provides a tool for the interpretation of many experimental observations from literature.

This book was released on 2022-07-11 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water diffusing into silica surfaces gives rise for several effects on diffusion behaviour and mechanical properties. In a preceding booklet, we focused on diffusion and fiber strengths and deformations which were obtained by water soaking under external loading. In the present booklet we deal with results and interpretations of strength increase in the absence of applied stresses.
Download or read book Dynamic Model based Analysis of Oxygen Reduction Reaction in Gas Diffusion Electrodes written by Röhe, Maximilian and published by KIT Scientific Publishing. This book was released on 2024-01-09 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work, the first simulation model of oxygen depolarized cathodes (ODC), which are silver catalyst-based gas diffusion electrodes, is presented that considers the phase equilibrium of the gas-liquid interface and structure-related inhomogeneities in electrolyte distribution. By means of the model it has been identified that mass transport of water and ions in the liquid phase is a crucial factor for electrode performance and how it is influenced by the electrode structure.

This book was released on 2022-07-01 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work aimed at designing, studying and producing the first prototypes of KIDs tailored for fusion plasma polarimetric diagnostics. Diamond was considered for the first time as substrate material for low-temperature superconducting detectors given its unmatched optical, radiation hardness and thermal qualities, properties necessary for working environments potentially saturated with radiation. This work represents a first step toward the optimization and final application of this technology.

Download or read book Inorganic Massive Batteries written by Virginie Viallet and published by John Wiley & Sons. This book was released on 2018-05-08 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the 90s, the Li-ion batteries are the most commonly used energy storage systems. The demand for performance and safety is constantly growing, current commercial batteries based liquid electrolytes or gels may not be able to meet the needs of emerging applications such as for electric and hybrid vehicles and renewable energy storage , and it is therefore necessary to develop advanced storage systems with characteristics such that the highest density of energy technology, long life, low cost of production, little or no maintenance and high safety of use. Batteries "all solid" are a technology of choice to meet these requirements. In this technology, the electrolyte separator between the two electrodes is no longer a liquid medium but a solid.

Download or read book Rational Design of Nanostructured Polymer Electrolytes and Solid Liquid Interphases for Lithium Batteries written by Snehashis Choudhury and published by Springer Nature. This book was released on 2019-09-25 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis makes significant advances in the design of electrolytes and interfaces in electrochemical cells that utilize reactive metals as anodes. Such cells are of contemporary interest because they offer substantially higher charge storage capacity than state-of-the-art lithium-ion battery technology. Batteries based on metallic anodes are currently considered impractical and unsafe because recharge of the anode causes physical and chemical instabilities that produce dendritic deposition of the metal leading to catastrophic failure via thermal runaway. This thesis utilizes a combination of chemical synthesis, physical & electrochemical analysis, and materials theory to investigate structure, ion transport properties, and electrochemical behaviors of hybrid electrolytes and interfacial phases designed to prevent such instabilities. In particular, it demonstrates that relatively low-modulus electrolytes composed of cross-linked networks of polymer-grafted nanoparticles stabilize electrodeposition of reactive metals by multiple processes, including screening electrode electrolyte interactions at electrochemical interfaces and by regulating ion transport in tortuous nanopores. This discovery is significant because it overturns a longstanding perception in the field of nanoparticle-polymer hybrid electrolytes that only solid electrolytes with mechanical modulus higher than that of the metal electrode are able to stabilize electrodeposition of reactive metals.
