Hybrids: The Best Use for Lithium
If you thought that the best way to reduce our use of petroleum, and its concomitant carbon dioxide emissions, is to switch to plug-in electric cars, then you are in for a surprise. It turns out that on a kilogram-for-kilogram basis, the biggest reduction comes from putting that lithium, in the form of lithium-ion batteries, into conventional hybrids. The least effective way to reduce gasoline use and CO2 is to put it in an all-electric car.
That sounds completely counter-intuitive, but that's the findings of a study done by researchers at the U.S. National Renewable Energy Laboratory (NREL) in Golden, Colorado. Leading the study was Senior Research Engineer Jeremy Neubauer, who talks with EV World in this MP3 'Future In Motion' podcast about their findings and what they see are its implications for future lithium resources and reserves.
The findings of the study are highlighted in a MS Powerpoint (.pptx) presentation entitled, The Impact of Lithium Availability on Vehicle Electrification that you can download from EV World's online digital library.
