Abstract

Improving the energy density of lithium (Li)-ion batteries remains important for a number of applications. In particular, high energy densities are required to extend the range of electric vehicles and minimize the space and mass of the battery pack. In the ongoing search for means to increase the energy of Li-ion batteries, the discovery of new positive electrode materials is of critical importance. The positive electrode is synthesized with lithium in it, some of which is removed during charging of the cell along with electrons that travel through the external circuit. The lithium is then reinserted into the material while the battery is discharged, which is accompanied by electrons traveling through the external circuit to do work. There are many challenges with respect to finding better positive electrode materials, the primary of which are increasing the volumetric energy density, lowering the cost, and improving the safety. Though safety is a very important issue with respect to Li-ion batteries, the focus of this thesis will be to maximize energy while trying to minimize cost.
