Increasing the life span of Li-ion cells

Nominated by:


Year: 2016

About the Innovation

Jeff Dahn and his dedicated team of researchers have pioneered the method of high-precision coulometry to rank the life span of Li-ion cells in a few weeks of testing. Not only has this development allowed researchers worldwide to speed up the R&D process and create a better and longer-lasting Li-ion cell, but it will also contribute to the switch of our energy sources from fossil fuels to renewable resources.

About the Innovator

A fellow of the Royal Society of Canada, Dr. Jeff Dahn is Canada’s most distinguished scientist in the field of advanced batteries. He has authored over 610 refereed journal papers and has had patents issued or filed for 65 inventions. Mr. Dahn worked at the National Research Council of Canada (1982-85) and at Moli Energy Limited (1985-90) before joining the Physics Department at Simon Fraser University in 1990. He was named the Natural Sciences and Engineering Research Council/3M Canada Industrial Research Chair at Dalhousie University in 1996, where he subsequently became a Canada Research Chair in 2003. In 2016, he will hold the NSERC/Tesla Canada Industrial Research Chair where he will focus on low-cost, long-lifetime Li-ion batteries.
