Electric Cars Waiting on the Battery
Kevin Bullis, Technology Review
There are plenty of reasons why electric cars aren’t catching on, but one problem is certain: the batteries cost far too much. For electric vehicles and plug-in hybrids to compete with gas-powered cars, battery prices need to drop by between 50 and 80 percent, according to recent estimates by the U.S. Department of Energy. Getting there might require inventing entirely new kinds of batteries, but there’s also a strong case that improvements to the lithium-ion batteries that power the current generation of electric vehicles may be enough.
