New batteries last 100 times longer than today's

Nothing is worse than having your cell phone or MP3 player die when you're out and about, which is why the possibility of new battery technology that has 100 times the capacity of today's cells is so exciting. Researchers at Brown University have created batteries that use plastic rather than metal to conduct electricity, combining a capacitor's power with the storage capacity of a battery. Apparently the batteries could be conceivably built in a variety of shapes, allowing a phone to be wrapped in a battery or a fabric could even be made of the material. The only problem is that as of now, the batteries lose their capacity quickly after being recharged a number of times. As soon as they get kinks like that worked out, look forward to not having to recharge your phone after talking on it for a half an hour.
