Phosphate intercalation materials are an integral chemistry for secondary lithium-ion batteries. The demand for energy storage technologies with higher energy and power densities is ever increasing, indicating a necessity for the development of new battery chemistries. The robust nature of phosphate groups is a strong platform for the development of new lithium-ion battery chemistries. From here, β-NbPO5 is realized as a positive electrode material for lithium batteries. With an operating voltage circa 2V, β-NbPO5 has the potential to be either the positive or negative electrode. In this thesis, the electrochemical stability of β-NbPO5 is improved using two different methods of altering the voltage window and utilizing a Ta5+ ionic substitution to form β-TaxNb1-xPO5. Preliminary electrochemistry of the end member β-TaPO5 is reported for the first time. The flat voltage profile, excellent reversibility, and low polarization make β-TaxNb1-xPO5 a good candidate for a model reference electrode material.
