Enabling the Next Generation of High Energy Lithium-Ion Battery Cathodes
This presentation will discuss insights into the atomic-level structure and transformation mechanisms of lithium-transition-metal-oxide cathode materials. These mechanisms explain, in part, the failure modes of layered cathodes at high states of delithiation. Furthermore, a discussion on a variety of elemental and structural compositions will be given. For example, unique layered, layered-layered, spinel, and layered-layered-spinel structures and chemistries will be presented that are pushing the boundaries of current Li-ion technology.
Future directions and research in further enabling these new systems will also be discussed.
