Abstract
Lithium ion batteries are becoming a popular choice for battery materials in hybrid electric vehicles and plug-in hybrid electric vehicles. Its success will depend on safety, efficiency, and materials cost. Research is being done on ways to create more stable cathode materials which will not cause oxidation of the electrolyte through the release of oxygen from the oxide host of cathode. Lithium containing olivine-structure of iron phosphate, LiFePO4, has already emerged as a safe and cheap cathode material. We are exploring the existence of new compositions and structures with the oxyanions (PO43- and BO33-) and transition metals. Currently, a ternary phase diagram is being explored using varying amount of BO33-, Li+, and PO43-, with fixed amounts of F-, H2O, and Fe2+ using hydrothermal reaction conditions. Products are then analyzed using single-crystal or powder X-ray diffraction. Some preliminary results of our investigation will be presented.
Biography
Patrick Stanley is a sophomore dual majoring in Chemistry and Chemical Engineering. He currently holds the vice president position of the W. T. Schrenk Society (An American Chemical Society student affiliate chapter), and the national liaison position for the Missouri S&T student chapter of the American Institute of Chemical Engineers. Apart from his studies and research, Patrick spends time working out and teaching taekwondo, spending time at the Catholic Newman Center, and geocaching. Originally from Auxvasse, Missouri, Patrick has an acute interest in plants and all things agricultural, as evidenced by his involvement in the National FFA Organization and he desires to apply his knowledge to the field agriculture after graduation. This summer, Patrick has an internship in Kearney, Nebraska, with the University of Nebraska - Lincoln: Partners in Pollution Prevention.
