Prototype Smartphone Battery Charges in Half a MinuteCategory: Science & Technology

One of the fears shared by all users of mobile electronics is running out of power, and having to wait and wait for it to recharge. For now we have few options but to keep a charger handy, get a larger battery, and/or keep a second battery ready, if possible. Researchers at Tel Aviv University and the start-up StoreDot may have a new option for the future as they have created a battery that can fully charge in 30 seconds.
This new battery uses nanodots, which are bio-organic semiconductors made of peptides and have special electrochemical properties. By adding them to a battery they can increase both electrode capacity and electrolyte performance. Being organic and natural, they can also be produced very easily and cheaply. To demonstrate their capability, the researchers built a prototype battery for the Samsung Galaxy S4 smartphone, and fully charged it in half a minute at a recent Microsoft conference.
While the public may be especially interested in nanodots for their batteries, they can also be used to build sensors and displays with better color reproduction. Presently the prototype charger is about the size of that for a laptop, but the researchers are working to shrink it and bring it to market for late 2016.
