Development Of A Multi-Scale Mechano-Electrochemical Battery Model, Drew J. Pereira
Development Of A Multi-Scale Mechano-Electrochemical Battery Model, Drew J. Pereira
Theses and Dissertations
As the automotive industry moves towards large format electric vehicles, such as trucks and SUVs, the need for highly efficient, energy-dense electrodes rapidly increases. Several promising active materials have been studied and proposed, however, many of these materials undergo significant volume change upon lithiation and de-lithiation. Cell and pack designers struggle to understand and predict how active material volume change at the particle scale will affect mechano-electrochemical behavior on the electrode, cell, and pack scales. Additionally, many of these active materials suffer in their cycle life due to a mechanically-driven degradation of the electrode matrix. Therefore, the focus of this …
Establishing Independent Tunability Of The Mechanical And Transport Properties Of Polymer Gels, Lucas Rankin
Establishing Independent Tunability Of The Mechanical And Transport Properties Of Polymer Gels, Lucas Rankin
Master’s Theses
Polymer gels can be used in the fabrication of materials for filtering liquid and gaseous media, solid-state electrolytes, and transdermal medical patches. This diverse range of applications primarily relies on the transport and mechanical properties of polymer gels. Both sets of properties have shown excellent tunability, but typically in a coupled fashion. Establishing the independent tunability of the transport and mechanical properties of polymer gels (using simple, cost-effective methods) is paramount if polymer gels are to be used to their full potential. Specifically, block copolymer gels self-assemble into organized nanoscale networks within the gel solvent, which allows for facile control …
Hydrophobization Of Cellulose-Based Fibers For Packaging Applications With Alkyl Ketene Dimers (Akd) And Food-Grade Waxes Via Supercritical Impregnation With Carbon Dioxide – Experimental And Thermodynamic Modeling Approaches, Kolawole Adenekan
Electronic Theses and Dissertations
This modified material has applications in food packaging, where frequently water-repellant surfaces are required. This method is preferable to traditional coating methods because it sizes across the entire thickness of the substrate rather than just the surface and can be used for non-planar surfaces; uses significantly less material than traditional methods and will be an excellent technique for multilayered and intelligent coating.
