Supercapacitors that can deliver a strong surge of electrical power could be manufactured from carbon nanotubes using a technique developed by researchers at UC Davis.

Supercapacitors are electrical storage devices that can deliver a huge amount of energy in a short time. Hybrid-electric and fuel-cell powered vehicles need such a surge of energy to start, more than can be provided by regular batteries. Supercapacitors are also needed in a wide range of electronic and engineering applications, wherever a large, rapid pulse of energy is required.
