Steve Posted March 12, 2009 Share Posted March 12, 2009 Scientists at MIT have developed a new design for lithium batteries that could cut recharge times down to seconds. Traditional lithium batteries dispense power slowly, but also charge slowly because of perceived limitations in the lithium itself. However, the team at MIT found that the problem lies not in the lithium, but in the substrate around it, according to a paper (PDF) published in Nature. The team, led by Gerbrand Ceder, the Richard P. Simmons Professor of Materials Science and Engineering at MIT, and Byoungwoo Kang, a graduate student in materials science and engineering, has created a battery that can be fully charged and discharged in under 20 seconds. “The ability to charge and discharge batteries in a matter of seconds rather than hours may open up new technological applications and induce lifestyle changes,” Ceder and Kang concluded in the paper. The team believe that the new technology could be available in two or three years, because it is based around the commonly used lithium battery.From vnunet.

d00ban Posted March 12, 2009 Share Posted March 12, 2009 like what? what do you use that needs discharging in a matter of seconds? (bar what heynuts said) Quote Link to comment Share on other sites More sharing options...
Giraffe Dung Posted March 12, 2009 Share Posted March 12, 2009 like what? what do you use that needs discharging in a matter of seconds? (bar what heynuts said) admittedly not as much stuff as stuff that needs charging in a matter of seconds. personally i think the more useful domestic application might be the charging bit rather than the discharging bit...

bruxism Posted March 12, 2009 Share Posted March 12, 2009 it's all about the electric cars innit. This means that realistically you could drive your electric car up to the servo, plug it in for a minute, and piss off for another 300 kilometres. Just like petrol cars, only more tree huggy.

Yeah and a fast discharge would be necessary if electric cars are ever going to be able accelerate to any decent extent. Quote Link to comment Share on other sites More sharing options...
Bubba Posted March 13, 2009 Share Posted March 13, 2009 Think about how many machines could be made cordless with a system like this? Or for example mobile phones: Plug em in for 30s and they hold for a couple of more days. This is a pretty niffty finding... Thanks for the news. Pee.z o.
