Abstract

Energy storage--Research Lithium ion batteries Vanadium oxide Materials Science
Energy storage has become a more prevalent subject in recent years, as society in general makes a move toward a more fully connected network of life. As such, many veins of research have been investigated to fill this demand for materials and methods. One such vein is the work contained herein. Batteries make much of this advancement -- they store energy that electronic devices of all kinds require to function. But the materials that exist and are well known are limited by factors such as elemental abundance and toxicity among others. Investigation into other solutions is imperitive, therefore, in order to meet the growing demand for electrochemical devices, and especially batteries The goal of this research project, therefore, is to first understand of how the variation of a chemical synthesis process called chemical preintercalation, that was developed here at Drexel, in order to understand the structure, properties, and performance of bilayered vanadium oxide. [delta]-Mg_xV₂O₅ · nH₂O (x = 0.01 - 0.37) and [delta]-TM_xV₂O₅ · nH₂O (TM = Mn, Co) were investigated using the chemical preintercalation synthesis approach to improve the electrochemical behavior of bilayered vanadium oxide in both sodium-ion and lithium-ion cells.
