Future power

July 8, 2008
Try to imagine life without lithium-ion batteries powering cellphones, laptops, digital cameras and cordless rechargeable construction tools. Jeffery Dahn can’t. As a pioneer of the lithium-ion battery, he is contributing to the search for a safe, environmentally friendly, long-lasting and stable power supply for the future.
 

At the Centre of Excellence in Materials Discovery at Dalhousie University, in Halifax — one of the largest university laboratories studying advanced battery- and fuel-cell-technology materials in the world — Dahn can accurately test more than 60 fuel-cell catalysts or lithium-ion-battery electrode materials at once. Other labs can test only one material composition at a time.

Where will it lead? So far, says Dahn, to pending patents.
“We want decent batteries that can be made economically at scale,” he says, “and not deplete the Earth’s resources or pollute the environment.”
