In Situ Study of Excess Lithium Metal Oxides Under Charge and Discharge

DOI

The next generations of Lithium batteries require materials with an enhanced energy density. The most realistic choice for such systems are the lithium rich electrodes (e.g. Li1.2Mn0.54Ni0.13Co0.13O2). These materials offer an increase in energy storage of around 1.5 times over conventional systems. Interestingly despite the similarity in the parent structure to traditional Lithium ion battery electrodes (LiCoO2) these compounds show a very different electrochemical performance. This involves a significant structural evolution on the first cycle which dramatically affects the subsequent charging and discharging of the battery. In this proposal we intend to elucidate the structural changes occurring and reveal fundamental information about how these materials operate. This data will be used to support research in our laboratory utilizing a large range of characterization techniques.
