Default Lithium battery that recharges in seconds

Battery that 'charges in seconds'



Geoff Brumfiel from Nature discusses how the new batteries work

A new manufacturing method for lithium-ion batteries could lead to smaller, lighter batteries that can be charged in just seconds.


A prototype battery made using the new technique could be charged in less than 20 seconds - in comparison to six minutes with an untreated sample of the material.
Most commercial batteries use a material made up of lithium and cobalt, but lithium iron phosphate does not suffer from overheating - something that has affected laptop and mp3 player batteries in a number of incidents.

Even though it is cheap, lithium iron Phosphate has until now received little attention because lithium cobalt batteries can store slightly more charge for a given weight. However, the researchers found that their new material does not lose its capacity to charge over time in the way that standard lithium ion batteries do. Read full story
