US scientists have developed a mobile phone battery that can be charged in a matter of seconds, in a development that could cut handsets' energy use and make them much more convenient to use.
The new battery, which is the brainchild of scientists at the world-renowned Massachusetts Institute of Technology, can be fully re-charged in around ten seconds.
Should the battery become standard in handsets, the days of charging a phone overnight could be gone forever and it could also usher in an era of smaller, lighter batteries.
This in turn could lead to the development of new handsets that are as slim as a credit card.
Meanwhile, the advent of an energy-saving battery could also help the mobile phone industry meet its environmental obligations.
Dr Gerard Ceder, who was the leading force behind developing the battery, said: “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.”
Mobile phone companies are currently under pressure from governments across the world to cut their environmental impact, with the result that many phones unveiled at a recent trade event included features such as automatic shut-off when the phone battery is full.
