Location: TUM-IAS Auditorium, Garching-Forschungszentrum
Agenda:
14:00 Introduction
14:05 Presentation
14:50 Discussion
Abstract:
Did you know that when a lithium-ion cell begins to fail the average cell voltage often INCREASES? I will explain why this happens and how this is very useful in detecting different failure modes in Li-ion cells. I will also discuss how simple measurements of the uniaxial pressure generated by pouch cells constrained between fixed plates can be used to help determine the best cell chemistries (electrolyte, electrode materials) very rapidly.
Bio:
Jeff Dahn is recognized as one of the pioneering developers of the lithium-ion battery that is now used worldwide in laptop computers and cell-phones. Dahn's recent work has concentrated on increasing the energy density, improving the lifetime and lowering the cost of lithium ion batteries. He is the author of over 640 refereed journal papers and co-inventor of 65 inventions with patents issued or filed. He obtained his B.Sc. in Physics from Dalhousie University (1978) and his Ph.D. from the University of British Columbia in 1982. Dahn then worked at the National Research Council of Canada (82-85) and at Moli Energy Limited (85-90) before taking up a faculty position in the Physics Department at Simon Fraser University in 1990. He returned to Dalhousie University in 1996. Jeff Dahn has received numerous awards including: International Battery Materials Association (IBA) Research Award (1995); Herzberg Medal, Canadian Association of Physicists (1996); ECS Battery Division Research Award (1996); Fellow of the Royal Society of Canada (2001); Medal for Excellence in Teaching (2009) from the Canadian Assoc. of Physicists, The Rio-Tinto Alcan Award from the Canadian Institute of Chemistry (2010), the ECS Battery Division Technology Award (2011), the Yeager award from the International Battery Materials Association (2016) and the Inaugural Govenor General's Innovation Award (2016).
