Diamonds in your devices: Powering the next generation of energy storage

Supercapacitors, which have begun to stand in for conventional batteries, such as Li-ion batteries, can currently store much less energy than is ideal. To remedy this, a group of scientists from Japan propose using conductive nanodiamond as electrode material. The resultant high-performance energy storage device is suited to applications that require rapid charging and discharging to occur multiple times over long durations. Yet again, the diamond shines above its peers.
