Sang-Don.Han@nrel.gov | 303-384-7815

Dr. Sang-Don Han received his M.S. degree in Environmental Science and Engineering from Gwangju Institute of Science and Technology in 2008, where he characterized the properties of ion-exchange membranes and used them to evaluate electrodialysis process performance.

His scientific training continued as a graduate student under Dr. Wesley Henderson at North Carolina State University. He investigated electrolyte materials for advanced energy technologies (e.g., batteries and supercapacitors) to understand the link between 1) electrolyte material structure (i.e., solvent/anion structure and solvation state of cations) and 2) electrochemical/transport properties. This work enabled the optimization of electrolyte materials formulation for better application performance and safety.

As a postdoctoral researcher at Argonne National Laboratory, he worked on electrolyte-electrode interface and electrode properties analysis under the guidance of Dr. Anthony Burrell and Dr. John Vaughey. A key focus involved investigating various processes, including (de)solvation of ions, reversible deposition on a metal anode, reversible intercalation on a cathode, and current-collector corrosion with the goal of developing next-generation high-energy-density batteries.

His current research interests are focused on delving into the interactions and properties of electrolytes, exploring new electrolytes, understanding cell operation mechanisms, and improving the electrochemical cell performance for advanced energy technologies.
