Breakthrough battery can charge up in seconds
Scientists in the United States have invented a battery that can charge in seconds, promising a revolution in power storage that could also help green cars and renewable energy.
The advance allows lithium-ion batteries, the standard variety used in consumer electronics and cells for electric or hybrid vehicles, both to charge and discharge stored energy more quickly than at present.
This should lead to smaller, lighter batteries for mobile phones and other devices, which can be fully charged when plugged in for a few seconds.
Lithium-ion batteries that can be recharged in a fraction of the time ... this is truly a game changer.
Imagine an electric vehicle that can be re-charged in minutes, rather than hours. This new process effectively removes the greatest obstacle to widespread acceptance of electric vehicles.
Scientists at M.I.T. say that the new batteries could be ready within 2 or 3 years.
