Charge Cellphone in Seconds Using 3D nanostructure!

Scientists at the University of Illinois has designed and developed an amazing 3D nanostructure, that may make it possible to recharge mobile phones in seconds or a laptop within minutes. It would also charge high power lasers and defibrillators, required in surgeries, without loss of time between pulses.

The research group wraps a thin film into 3D structure, achieving both high active volume (high capacity) and large current. They have demonstrated battery electrodes that can charge or discharge in a few seconds, 10 to 100 times faster than equivalent bulk electrodes, yet can perform normally in existing devices. [via]
