Title: A personal story about 30 years of development of Ni-rich positive electrode materials for Li-ion batteries


Dr. Dahn will discuss the discovery of LiNiO2, its promise and its problems. He will show how and why so-called NCA [LiNi(1-x-y)Co(x)Al(y)O2] was created to overcome the deficiencies of LiNiO2. Today, given the high cost of cobalt, researchers are trying to eliminate cobalt altogether from NCA - Dahn will demonstrate how this can be done.


Jeff Dahn 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.  At Moli, he did pioneering work on lithium-ion batteries.  He has over 700 refereed journal publications and over 68 distinct inventions with patents issued or filed.  His H-index is 124 according to Google Scholar.

Dr. Dahn was appointed as the NSERC/3M Canada Industrial Research Chair in Materials for Advanced Batteries at Dalhousie University in 1996, a position that he held until 2016.  In 2016, Dr. Dahn began a research partnership with Tesla Motors as the NSERC/Tesla Canada industrial research chair. 

Dahn’s research in the lithium-ion battery field has been recognized by numerous awards including a Governor General’s Innovation Award (2016) and the Gerhard Herzberg Gold Medal in Science and Engineering (2017), Canada’s top science prize.  He was awarded the Canadian Association of Physicists Medal for Excellence in teaching in 2009.

Dr. Dahn’s wife Kathy, daughters Hannah and Tara, and son, Jackson, are all Dalhousie graduates. They reside in Halifax, Nova Scotia.
