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.
The United States could have the capacity by 2015 to produce enough battery packs for 500,000 cars. But this year, due to high prices, plug-in vehicle sales won’t even reach a tenth of that in the United States. As a result, advanced battery makers in the United States have struggled. A123 Systems went bankrupt.
