Book Synopsis On the Electro-Chemo-Mechanical Coupling in Solid State Batteries and its Impact on Morphological Interface Stability by : Ganser, Markus

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. This book was released on 2021-03-09. 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.

Download or read book Modeling transport properties and electrochemical performance of hierarchically structured lithium-ion battery cathodes using resistor networks and mathematical half-cell models written by Birkholz, Oleg. This book was released on 2022-10-05. Available in PDF, EPUB and Kindle. Book excerpt: Hierarchically structured active materials in electrodes of lithium-ion cells are promising candidates for increasing gravimetric energy density and improving rate capability of the system. 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.

Book Synopsis Application of Data Mining and Machine Learning Methods to Industrial Heat Treatment Processes for Hardness Prediction by : Lingelbach, Yannick

Download or read book Application of Data Mining and Machine Learning Methods to Industrial Heat Treatment Processes for Hardness Prediction written by Lingelbach, Yannick. This book was released on 2024-07-24. Available in PDF, EPUB and Kindle. Book excerpt: This work presents a data mining framework applied to industrial heattreatment (bainitization and case hardening) aiming to optimize processes and reduce costs. The framework analyses factors such as material, production line, and quality assessment for preprocessing, feature extraction, and drift corrections. Machine learning is employed to devise robust prediction strategies for hardness. Its implementation in an industry pilot demonstrates the economic benefits of the framework. - This work presents a data mining framework applied to industrial heattreatment (bainitization and case hardening) aiming to optimize processes and reduce costs.

Book Synopsis Multiscale Modeling of Curing and Crack Propagation in Fiber-Reinforced Thermosets by : Schöller, Lukas

Download or read book Multiscale Modeling of Curing and Crack Propagation in Fiber-Reinforced Thermosets written by Schöller, Lukas. This book was released on 2024-03-15. 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.

Book Synopsis Consequences of hydroxyl generation by the silica/water reaction - Part I: Diffusion and Swelling by : Fett, Theo

Download or read book Consequences of hydroxyl generation by the silica/water reaction - Part I: Diffusion and Swelling written by Fett, Theo. This book was released on 2022-07-11. 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.
