Quantitative understanding of electrode potential E’s electrolyte dependence has been limited to the classical Debye-Hückel theory where Coulombic interactions are approximated under the ultimately diluted condition. Therefore, the quantitative expression of E for practical electrochemical systems has long been a holy grail. Research led by Atsuo Yamada has shown that liquid Madelung potential (ELM), which is analogous to the conventional concept in solid-state science, can be used for explicit physical treatment of Coulombic interactions. During this seminar, Yamada will show how the ELM shift given by molecular dynamics calculations accurately reproduced a hitherto unexplainable and huge experimental shift. A long-awaited concept to quantify the large variation of electrode potential in any electrochemical system is now available.

About the speaker

Atsuo Yamada has had a unique career in academic and industrial research. After serving as a laboratory head of Sony Research Center, he was appointed as an associate professor at Tokyo Institute of Technology in 2002 and a full professor at the University of Tokyo in 2009. During this period, he joined John. B. Goodenough’s laboratory at the University of Texas at Austin as a visiting scholar for one year and was called for a sabbatical stay from the University of Bordeaux as an invited professor to enhance research communication with Dr. Claude Delmas in ICMCB/CNRS.

His diverse research is recognized for his sophisticated approaches with structure-property relationships, including very early-stage exploration/optimization of lithium-iron phosphate and the identification and understanding of several functional electrolytes. He holds 90 patents, has published 25 chapters and well over 270 referenced journal papers, and has delivered 125 invited presentations, for a total citation exceeding 30,000. He is ranked as a Highly Cited Researcher by Clarivate Analytics and is now serving for the scientific advisory board of Advanced Energy Materials.

He has been awarded the Spriggs and Purdy Awards from the American Ceramic Society, the Scientific Achievement Award from ECS Japan, the IBA Research Award from International Battery Association, and the Battery Division Research Award from the Electrochemical Society.
