Still, MIT materials science and engineering professor Gerbrand Ceder and others said the safety problems can be fixed.
Change doesn't come often in the battery field.
"The big advances in battery technology happen rarely. It's been more than 200 years and we have maybe five different successful rechargeable batteries," said George Blomgren, a former senior technology researcher at Eveready and now a private battery consultant. "It's frustrating."
Alessandro Volta — for whom the volt is named — invented the first useful battery in 1800. That was long before other breakthrough inventions like the internal combustion engine, telephone, car, airplane, transistor, computer and Internet. But all of those developments have seemed to evolve faster than the simple battery.
The lead-acid car battery "has been around for 150 years more or less," Whitacre said. "This is a remarkable testament to first how robust that chemistry is and how difficult change is."
Battery experts are split over what's next. Some think the lithium ion battery can be tinkered with to get major efficiency and storage improvements. Amatucci said he thinks we can get two to three times more energy out of future lithium ion batteries, while others said minor chemical changes can do even more.
But just as many engineers say the lithium ion battery has run its course.
"With the materials in the current lithium ion battery, we are definitely plateaued," Blomgren said. "We're waiting for something to come along that really does the job."
There are all sorts of new type batteries being worked on: lithium-air, lithium-sulfur, magnesium, sodium-ion.
"Right now it's a horse race," Blomgren said. "There's deficiencies in every technology that's out there. Each one of them requires a major solution."
One of the nation's best hopes for a breakthrough, said Battaglia, is John Goodenough, the man responsible for the 1979 breakthrough that led the first commercial lithium ion battery in 1991. He will receive the National Medal of Science at the White House next month.
Goodenough is 90.
"I'm working on it," Goodenough, an engineering professor at the University of Texas at Austin, said Tuesday. "I'm optimistic in a sense that I'm willing to keep working on it. I think we can do some interesting things."
