When: December 7, 2023
5:00 PM-8:30 PM
Where: Stonewood Ale House
601 Mall Dr
Schaumburg, IL 60173
Speaker: Dr. Hakim Iddir
Physicist, Argonne National Laboratory
Topic: Atomistic modeling of battery materials
Speaker Biography:
Dr. Hakim Iddir is a Physicist in the Chemical Sciences and Engineering Division at Argonne National Laboratory (ANL).
Dr. Iddir holds a Ph.D. in Physics from the University of Illinois at Chicago, a Master of Chemical Engineering from the Illinois Institute of Technology in Chicago. Dr. Iddir joined Argonne National Laboratory in 2006.
His research interests are in the area of materials science, with a focus on developing experimental and theoretical approaches for investigating structure-property relationships at the atomic scale, defects, surfaces, interfaces in materials, chemical and physical properties of catalytic, non-catalytic and energy materials. His approach involves the use of ab-initio thermodynamics and materials modeling tools along with of electron microscopy and spectroscopy techniques.
Dr. Iddir published several scientific papers and patents, and serves as a reviewer for several scientific journals, the National Science Foundation, and the Vehicle Technologies Office of the Department of Energy.
Presentation Abstract:
Cathode materials with improved energy densities, longer cycle-life, and improved safety characteristics are needed for portable electronic devices, smart grid systems, and transportation technologies. The highest energy-density cathode materials are based on transition metal oxides, such as layered LiMO2 (M = Co, Ni, Mn), and lithium and manganese-rich composite layered transition metal oxide (LMR-NMC) materials. These cathode materials can address some of the challenges associated with next-generation energy storage devices. However, sufficient knowledge on the atomic scale structure, local environment, and processes governing these metrics in working cells is still lacking.
Herein, I will present few examples of current interest to the Li-ion battery research community using density functional theory to provide few insights on select structure-property relationships, such as particle morphology, elemental segregation, surface reconstruction, cathode-electrolyte interaction, bulk stability, and Li transport (anode-fast charge).
