Jeff Dahn

Jeff Dahn (born in 1957 in the United States and emigrated to Nova Scotia, Canada in 1970) is a Professor in the Department of Physics & Atmospheric Sciences and the Department of Chemistry at Dalhousie University. He is recognized as one of the pioneering developers of the lithium-ion battery, which is now used worldwide in laptop computers, cell-phones, automobiles, and many other mobile devices. Although Dr. Dahn made numerous contributions to the development of lithium-ion batteries, his most important discovery was intercalation of Li+ ions into graphite from solvents comprising ethylene carbonate, which was the final piece of the puzzle in the invention of the commercial Li-ion battery. Nevertheless, Dahn was not selected for the 2019 Nobel Prize in Chemistry, which recognized only John Goodenough, M. Stanley Whittingham, and Akira Yoshino.

Education Dahn obtained his B.Sc. in Physics from Dalhousie University in 1978 and his Ph.D. from the University of British Columbia in 1982.

Career Following his PhD, Dahn did research at the National Research Council of Canada from 1982 until 1985, before working at E-One Moli Energy until 1990. At that time, he took up a faculty position in the Physics Department at Simon Fraser University. In 1996 Dahn returned to Dalhousie University as a professor in the Department of Physics & Atmospheric Sciences and began to focus his research on lithium-ion batteries.

From the time he started doing research, Dahn has worked closely with industry. During his years at Simon Fraser University he worked with E-One Moli Energy. Upon moving to Dalhousie in 1996, Dahn became the NSERC/3M Canada Industrial Research Chair in Materials for Advanced Batteries, a position he was to hold for the next 20 years. In June 2016, Dahn began a 5-year research partnership with Tesla Motors to improve the energy density and lifetime of lithium-ion batteries and reduce their cost. In 2021 Dahn and his team at Dalhousie University extended the research contract with Tesla for another 5 years. Also in 2021, Dahn was named Chief Scientific Advisor to Novonix, an Australian-based battery materials and technology company. Effective June 15, 2023 Jeff Dahn is on the Scientific Advisory Board for Metamaterials, Inc. (Nasdaq:MMAT)(FSE:MMAT)

Awards and honors Dahn has received numerous awards: Research Award, International Battery Materials Association (1995) Herzberg Medal, Canadian Association of Physicists (1996) Research Award, ECS Battery Division (1996) Fellow of the Royal Society of Canada (2001) Medal for Excellence in Teaching, Canadian Association of Physicists (2009) Rio-Tinto Alcan Award, Canadian Institute of Chemistry (2010) Technology Award, ECS Battery Division (2011) Yeager Award, International Battery Materials Association (2016) Inaugural Governor General's Innovation Award (2016)
