Paul Mayne, Western News Western Engineering professor Andy Sun, Canada Research Chair in Development of Nanomaterials for Clean Energy, is working toward increasing the performance of electric cars, by using lithium iron phosphate batteries. While you may see a Chevrolet Volt here, or a Nissan Leaf there, the future of the electric car has a way to go when it comes to safety, cost and, especially, performance. However, Engineering professor Andy Sun may have an answer to that final challenge. Recently published in Nature Communications, Sun’s research showed, for the first time, carbon coating on electric car batteries not only affects conductivity and performance, but also alters the chemistry of the battery material’s interactive surface. Unlocking this secret may lead to better batteries – and longer distances traveled on the road – for these vehicles. Currently, the average electric car gets 90 kilometres per charge. Paul Mayne, Western News “So, it’s best only in the city,” Sun said. “For the highway, 90 kilometres is not enough. That’s why we want to develop a battery with much higher capacity. You can make bigger batteries to run longer, but they’re too big for the car. “Like a computer, you want to
