They call themselves the 'Dahn lab' graduates, and they're powering an unlikely, Halifax-based research hub for batteries designed to replace fossil fuels.
Jeff Dahn, professor of chemistry and physics at Dalhousie University and recipient of the Olin Palladium Award from the Electrochemical Society, poses for a portrait in a research lab of the Dunn Building, in Halifax, Thursday, Oct. 19, 2023. THE CANADIAN PRESS/Kelly ClarkThey call themselves the "Dahn lab" graduates, and they're powering an unlikely, Halifax-based research hub for batteries designed to replace fossil fuels.
They're scientists who delve deeply into chemistry and physics, yet Dahn describes the mission driving the work in fairly simple social terms. "It's a war on climate change. We need every sensible energy storage technology to store energy from solar and wind," he said after receiving his prize at the Electrochemical Society's biannual gathering in Sweden.
Today, the professor says there are 40 people at his Dalhousie lab, two new professors have been hired to "take over" when he eventually retires, and the storehouse of battery intelligence is flowing among his former acolytes as they seek ways to increase battery lifetimes. While studying with his mentor in 2009, Burns helped create higher-precision systems that test the endurance of lithium-ion cells. He and fellow researcher David Stevens used their findings to create Novonix Ltd., offering what Dahn calls the "most accurate" battery testing systems in the world.
Meanwhile, Novonix is building a production facility for battery electrode materials — synthetic graphite — in Tennessee that he hopes will tie in with the battery "giga factories" being constructed across North America to build systems for vehicles and other uses. It's expected to begin production late next year.
"Some of the findings , which are in the public domain, allow us to design these cells to withstand high temperatures and still maintain their capacity," he said.
