We are a lithium-ion battery materials research group within CSE with a focus on cathode materials, advanced characterization, and spectroscopy. We actively collaborate with groups involved in scale-up engineering, snycrotron-based characterization, materials coatings, and material modeling.
Our current projects focus on in-depth studies of high-voltage high-energy lithium-ion battery cathodes. We have active projects
- studying the bulk and interfacial behavior of layered and spinel-type cathode materials. We are investigating the relationship between synthesis, composition, electrochemical window, and processing of low-cobalt containing systems as alternatives to currently used cathode materials.
- identifying next generation materials coatings techniques and their role in stabilizing the cycling performance of a variety of commercially relevant materials. Our focus has been on developing new types of coatings based on atomic layer deposition (ALD) techniques and we actively collaborate with the Elam Group (Argonne).
- studying the underlying materials degradation pathways of cathode materials used under fast charging conditions.
- developing scale-up techniques (with the Materials Engineering Research Facility (MERF)) to understand the role of synthesis at scale and materials issues associated with moving from lab scale to pilot plant scale.
