Soo Kim

Research Interests:


I have designed experiments and computational simulations for the following topics: Li-ion batteries (LIB), Na-, Mg- batteries, fuel cells, and nano(energy)materials. In our research group, we aim to predict the materials properties based on density functional theory (DFT) calculations. In fact, it is very useful to experimentally design energy devices (e.g. batteries), when the thermodynamic materials properties are already predicted from the DFT calculations. Additionally, beyond the quantum mechanical theory, it is also critical to understand/investigate the following scientific phenomenon at multiple scales; i.e. microscopic diffusion behavior, mass and heat transport properties, complex chemical (competing) reaction mechanisms, and experimental visualization/verification.


Research Performed at Northwestern University During PhD:

First-principles calculations on Li-, Na-, and Mg-batteries


Biography:

I have both experimental and computational research backgrounds before coming to Northwestern University. I worked with Professor Phil Savage and Dr. Greg DiLeo as an undergraduate researcher at the University of Michigan in Ann Arbor to study the hydrogen gas productions via supercritical water gasification (SCWG). At Carnegie Mellon, I developed a tubular solid oxide fuel cell (SOFC) continuum fluid dynamic (CFD) computational model with Professor Myung S. Jhon and Professor Lorenz T. Biegler.

I moved back to Korea and worked in Samsung as a research engineer with Dr. Chunjoong Kim to develop various LIB cathode materials (LiFePO4, Li4Ti5O12, NCM, etc.) in lab- and industrial-scale (2009-11). Then, I joined the Center for Energy Convergence Research as a research staff at Korea Institute of Science and Technology (KIST) to synthesize and understand more advanced LIB cathode materials such as Li2MnO3-stabilized layered-layered structures (2011-13), collaborating with Dr. Byung-Won Cho and Dr. Kyung Yoon Chung. At KIST, we also worked on other electrochemical systems other than LIB, for example, Mg-battery and Mg-Air batteries [Video Link on Mg-Air Battery Car Tested at KIST].

Soo worked on several Mn-based cathode materials using DFT, in collaborations with battery scientists at Argonne National Laboratory (Dr. Michael M. Thackeray, Dr. Jason R. Croy, and Dr. Eungje Lee), while staying at Northwestern.  Within the department, Soo has closely worked with research scientists at Prof. Mark Hersam's research group. Soo was recently selected as the winner of Edward G. Weston Summer Fellowship to pursuit of work in a field of interest to the Electrochemical Society (ECS). In addition, Soo just won the 2018 ECS Industrial Electrochemistry and Electrochemical Engineering (IEEE) H. H. Dow Memorial Student Achievement Awardestablished in 1990 to recognize promising young engineers and scientists in the field of electrochemical engineering and applied electrochemistry. This award was made possible by a gift from the Dow Chemical Company Foundation and is intended to encourage the recipient to continue his career in electrochemical engineering or applied electrochemistry.

Soo moved to MIT on October, 2017 to start as a Postdoc Researcher working for Prof. Yang Shao-Horn in the Electrochemical Energy Lab (EEL).
