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]
