Discovering and delivering sustainability in a scientific, quantitative and measurable manner; meeting the global challenge of complex sustainable system of systems; and facilitating access and success in sustainability education at all levels are key elements of Purdue’s strategic approach.
In this first all electronic distribution issue of Discover EnergyTM you will learn more about the Energy Center’s activities over the spring 2009 semester. You’ll find that we’ve been fortunate to have two of Purdue’s great alumni share their Hydrogen expertise with our students and research community. You’ll also read about Purdue’s Nuclear Engineering program, Green Building initiative, Sustainability Council, Indiana Advanced Battery Research, and meet two of our newest Advisory Council members.
We look forward to receiving your comments at email@example.com. Please tell us if you feel that going all electronic is a good idea.

The recent recall of hoverboards because of exploding lithium-ion batteries highlights the danger of overheating batteries. Amy Marconnet, an assistant professor of mechanical engineering, can speak about the effects of excessive heating in batteries. Marconnet (pronounced mar-co-nay) founded the Marconnet Thermal and Energy Conversion Lab, where researchers are dissecting the batteries and testing materials making up electrodes and a critical component called a separator. (A video is available at https://www.youtube.com/watch?v=qCTMA8sxZO0) Battery failures have been reported in products ranging from commercial airliners and laptops to hoverboards and cellphones. Chemical reactions in the batteries generate heat while discharging and charging. The separator is a layer of material between the positive and negative electrodes. When it fails due to high heat, the battery short-circuits and could explode.Read Full Story
