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. Provided by Wikipedia
