Will the much needed breakthrough battery please stand up?

What do grounded Boeing 787s and plug-in cars have in common – it’s the lowly lithium-ion battery of which we ask the impossible on a regularly recurring basis.

At a local event surrounding the press tour of the Ford Focus plug-in, one speaker tried to simplify the complex chemistry and physics of battery power by saying you take anything from the left of the Periodic Table and mix it with something from the right side and you create something that wants to explode. Batteries slow this process to where we can tap this explosive energy over time.

Given the right ambient conditions and flaws, the lead-acid batteries in our cars as well as the lithium-ion batteries in Dreamliners can overheat, cause fires or even explode.

A just posted AP story explains this is the main reason our cities aren’t filled with electric cars right now – it is the batteries that are holding us back. The lithium-ion battery is the latest level of battery technology and it has been around for nearly 25 years.

Many people look to the leading authority on battery technology John Goodenough, the man that essentially made first commercial lithium-ion batteries possible back in 1991. He will be honored with the National Medal of Science at the White House next month at the age of 90.

Currently the engineering professor at the University of Texas at Austin, Goodenough told the AP, "I'm working on it. I'm optimistic in a sense that I'm willing to keep working on it. I think we can do some interesting things."

Boeing made extensive use of lithium-ion technology in the design of their new airplane. This was the ultimate cause of a fire aboard a Dreamliner in Boston, and another such incident in Japan. These events were sufficient to lead authorities to ground the fleet worldwide, but the problem of overheating batteries is not a new one.

Just six years ago, during 2006 and 2007, over 46 million cellphone and 10 million laptop batteries were recalled for risks of overheating, short-circuiting and exploding. These were all lithium-ion batteries and this resulted in the addition of safety features in consumer electronics.

This problem is produced by the fact we are working at cross purposes – if a battery is good at storing energy, it is slow to give it up. If it is good at releasing energy, it is a poor way to store it. In a nutshell, this is why it’s not easy to get great range out of a single charge in an electric car.

"We need to leapfrog the engineering of making batteries," stated Lawrence Berkeley National Lab battery scientist Vince Battaglia. "We've got to find the next big thing."

No one really has a clue what that will be or when it will become apparent.

The Obama administration has spent more than $2 billion to spark innovation in the advanced battery industry, simply because they are crucial to a greener energy future. This level of concentration in one area of science has not been seen since the Manhattan Project was charged with developing the atomic bomb.

unless you are ignoring history before 1800, the FIRST battery may have been the 'baghdad batteries' used thousands of years ago! We all have been taught many lies, hope this opens some eyes. peace The Baghdad Battery is believed to be about 2000 years old (from the Parthian period, roughly 250 BCE to CE 250). The jar was found in Khujut Rabu just outside Baghdad and is composed of a clay jar with a stopper made of asphalt. Sticking through the asphalt is an iron rod surrounded by a copper cylinder. When filled with vinegar - orany other electrolytic solution - the jar produces about 1.1 volts.
I remember seeing images of this device but forgive me for not pointing out that Volta invented the battery in its modern form. Anyone know what they did with 1.1 volts 2000 years ago?
Check out the hieroglyphs in Egypt, they give a lot of clues.
From the National Fire Protection Association Fire Analysis and Research Division "In 2003-2007, U.S. fire departments responded to an average of 287,000 vehicle fires per year. These fires caused an average of 480 civilian deaths, 1,525 civilian injuries, and $1.3 billion in direct property damage annually." But no one is bothered about gasoline but a battery.... big big problem.
Thanks, Doc - had no idea car fires were that big a problem. Guess the moral is life is dangerous, no?
There are a lot of lithium chemistry derivatives being tested right now, to name a few, lithium air, lithium sulfur, lithium phosphates. Each are promising in their own ways. IBM says they are pretty much ready as far as the technology used for lithium-air, the problem is finding a way to make sure no condensation gets in. I don't think the problem is with lithium-ion batteries per se but how to maintain it in a safe way. This morning I wrote an article that highlights how Tesla is working with the current crop of lithium-ion laptop batteries keeping in mind that failure is imminent while carmakers give lithium battery manufacturers stringent parameters with less success. The trick now is to make due with what we have, which pays for R&D for future chemistry. One thing I saw that was promising was mixing lithium-ion with ultracapacitors and load-balance the energy drawn and recouped. We're only at the beginning of batteries in moving vehicles, even if batteries have existed for millenniums.
