Presented by:
Rüdiger Kötz, Head of Capacitor Interface Group, Electrochemistry Laboratory, Paul Scherrer Institute

After postdoctoral years at the Case Western Reserve University in Cleveland, Ohio and at the Fritz Haber Institut der Max Planck Gesellschaft in Berlin, Dr. Kötz joined the ABB Corporate Research Centre in Baden, Switzerland in 1982. Since 1989 he has been leading the capacitor and interface analysis group of the Electrochemistry Laboratory at Paul Scherrer Insitut (PSI) in Switzerland. Throughout his career his research continued to aim at the characterization of the solid electrolyte interphase, the understanding of electro-active materials and the extrapolation of electrochemical processes to application.
