Sergiy Sazhin, Ph.D.

Research and Development Scientist/Engineer

Research Areas:
Energy Storage

Biography:
Dr. Sergiy V. Sazhin is a principal research scientist and engineer at the Idaho National Laboratory (INL). He has extensive academia and industrial experience in electrochemical power sources with prominent organizations throughout the world as a scientist, technologist, and project manager. He started his career at the Ukrainian Academy of Sciences leading projects on a large variety of battery systems and on fundamental studies. While working for Samsung Corp., South Korea, he launched R&D on new electrolytes, electrolyte purification techniques, and electrode development for industrial lithium-ion battery design. Dr. Sazhin then emigrated to the U.S.A. At Moltech Corp., he managed an electroanalysis team that worked on development of lithium-sulfur battery electrolytes and on accelerated tests. At Rayovac Corp., he led projects on lithium-carbon monofluoride batteries and on lithium-ion batteries. Now, at INL (since 2007), he provides synergy between his academia and industrial knowledge for the Energy Storage and Advanced Vehicle department programs. He is the principal investigator on diagnostic and prognostic testing of advanced batteries for electric vehicles and new methods of electrochemical characterization of battery components. His work has resulted in 46 patents/invention publications, 86 paper and conference publications, and several awards including national recognition. He has contributed to a number of battery technologies, molten salt systems, and active material coatings. Dr. Sazhin has also developed new testing methods for advanced battery materials and battery characterization, including a new approach for battery health estimation that improves safety and helps prevent catastrophic failure events.
