Aqueous Redox Flow Batteries With Boron Doped Diamond As An Electrode., Alex M. Bates
Electronic Theses and Dissertations
As the interest and implementation of renewable energy accelerates, so does that of grid energy storage. It is widely believed that a cost-effective energy storage technology will bring about the proliferation of renewable energy. Redox flow battery (RFB) technology represents a promising solution to cost-effective grid energy storage. Compared to other technologies, RFBs have a long lifetime, high efficiency, are non-flammable, significantly reduce cost, and separately scale power and energy. The separation of power and energy enables increased energy capacity by simply adding electrolyte volume. Of the challenges facing RFB technology, one readily apparent is the cost of the active …

Electronic Theses and Dissertations
As renewable energy sources, such as photovoltaic (PV) cells and wind turbines, are rapidly implemented in DC microgrids, energy storage systems play an increasingly significant role in ensuring uninterrupted power supply and in supporting the reliability and stability of microgrid operations. Power electronics, especially bidirectional DC–DC converters, are essential parts in distributed energy storage and alternative energy systems because of their grid synchronization, DC power management, and bidirectional power flow capabilities. While there is increasing demand for more efficient, compact, and reliable power converters in numerous applications, most existing power converters are hindered by traditional silicon (Si) based semiconductors, which …

Nanoscale Electrode Architectures For Electrochemical Energy Conversion And Storage., Venkat Kalyan Vendra
Electronic Theses and Dissertations
Nanoscale electrode architectures are at the heart of photoelectrochemical devices converting sunlight into electricity and electrochemical devices that store energy. Advanced nanomaterials encompassing 1-D architectures such as single crystalline metal oxide nanowires, 2-D architectures such graphene nanosheets and nanoparticle-nanowire hybrids have garnered significant interest as promising materials for fabricating thicker electrodes due their unique electronic, phase transformation and strain relaxation properties. However, electrode architectures incorporating these advanced nanomaterials will have a transformational impact on large scale electrode manufacturing only if the challenges associated with the electrode durability are addressed. At a fundamental level, the reactions happening at the electrode-electrolyte interface …
