Abstract
The focus of this work is looking at and understanding various vanadate materials and their applications in energy storage. Specifically, the use of vanadium oxides with lithium-based battery chemistries. Vanadium oxides have been investigated as a quaternary glass system with Li2O, B2O3 and Al2O3 additions while V2O5 is the main component. Deep structural investigation of this glass and heat-treated glass-ceramic was done with various techniques including nuclear magnetic resonance techniques, X-ray Diffraction, X-ray photoelectron spectroscopy, and electron paramagnetic resonance. These materials glass and glass-ceramic materials were also investigated electrochemically and were shown to have reasonable performance with the glass out-performing glass-ceramics on stability. The vanadium glass shows much promise as a reversible cathode for lithium metal batteries but dissolution with the electrolyte is a limiting factor. Vanadium oxides in the vanadium bronze structure found in the glass-ceramic are synthesized separately are also used in a scoping study for use in aqueous based Zinc-ion battery chemistries. Vanadium has shown a unique ability to accept a wide range of ionic species. This combined with its relative abundance makes it a key candidate to fulfill many energy storage demands from grid energy to portable electronics. However, better mechanistic understanding of the intercalation reaction as well as electrolyte stability must be addressed for both lithium and zinc systems if vanadium oxides are to be used commercially.
