Ex-GM engineer spearheads Bright Automotive's efforts to build 100-mpg hybrid truck
December 19, 2008
Led by Chrysler, GM and Delphi veterans, Bright is designing a 100-mile-per-gallon light truck assisted by electric power stored on the vehicle in a massive lithium-ion battery recharged from a wall socket. The goal: Get an assembly line going by 2012 for mass production of a high-tech truck known as a plug-in hybrid.

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
