Dr. Jae Jin Kim’s research interests broadly lie in the areas of materials synthesis/characterization and electrochemistry/physics of charge/mass transport in solids/interfaces for electrochemical energy conversion and storage technologies, including high temperature solid oxide cells, lithium/multivalent ion batteries, and lead-acid batteries. He has extensive experience in advanced in situ/operando materials characterization such as synchrotron-based X-ray techniques. He holds B.S and M.S. from Seoul National University and Ph.D. from Massachusetts Institute of Technology; all in Materials Science and Engineering.
