Building better batteries
Canada Research Chair Linda Nazar is turning her attention to lithium-sulfur (Li-S) and lithium-oxygen (Li-O2) batteries. Because of their energy density, they have the potential to achieve a far higher energy density than their lithium-ion counterparts.
Plug-in hybrid electric vehicles and pure electric vehicles are better for the planet. They generate less pollution and less greenhouse gas emissions.
So why don't we see more of them on the roads? Blame the battery. The lithium-ion versions currently used simply don't have the capacity that drivers want. A Nissan Leaf, for example, can travel only 100 miles on a single charge.
