Understanding The Interfacial Reactions Initiating On Lithium Metal Surfaces In Next-Generation Battery Technologies, Joshua A. Lochala Jul 2020

Understanding The Interfacial Reactions Initiating On Lithium Metal Surfaces In Next-Generation Battery Technologies, Joshua A. Lochala

Graduate Theses and Dissertations

Li-ion batteries have started to reach the theoretical maximum energy. Next-generation batteries represent the future of portable energy sources for vehicle electrification and grid energy storage. Li metal battery is one of the most promising next-generation battery technologies that could potentially double the cell-level energy of conventional Li-ion batteries. However, Li metal has multiple drawbacks that require addressing before realization. These drawbacks include dendrite formation leading to internal short and increasing internal resistance due to the breakdown of electrolyte, leading to rapid cell death. These problems stem from the interfacial reactions occurring during the plating and stripping of Li metal. …


First-Principles Studies Of Anion Engineering In Functional Ceramics, Steven Timothy Hartman May 2020

First-Principles Studies Of Anion Engineering In Functional Ceramics, Steven Timothy Hartman

McKelvey School of Engineering Theses & Dissertations

Ceramic materials display a wide variety of valuable properties, such as ferroelectricity, superconductivity, and magnetic ordering, due to the partially covalent bonds which connect the cations and anions. While many breakthroughs have been made by mixing multiple cations on a sublattice, the equivalent mixed-anion ceramics have not received nearly as much attention, despite the key role the anion plays in the materials’ properties. There is great potential for functional ceramics design using anion engineering, which aims to tune the materials properties by adding and removing different types of anions in existing classes of ceramic materials. In this dissertation, I present …


Battery Application Of Silver Molybdate Materials, Brendan Michael Godsel Apr 2020

Battery Application Of Silver Molybdate Materials, Brendan Michael Godsel

Undergraduate Honors Papers

As the demand for renewable energy grows, the investigation of potential battery materials continues to progress hastily. Many devices and machines of present day are operated by battery technology, and their energy requirements warrant which kinds of batteries will power them. The battery in a phone requires hundreds, possibly thousands, of uses and needs to be able to recharge quickly. The battery in the implantable cardiac defibrillator (ICD), the battery by which this product was inspired, is only used once, but it must last years before it is replaced. The cathode of the ICD battery is comprised of a silver …
