Graphene supercapacitors are moving from lab curiosity to serious contender for the next wave of electric vehicle energy storage. By pairing the near-instant charging of capacitors with the high ...

A new material called multiscale reduced graphene oxide could mean faster charging and power delivery than traditional ...

Supercapacitors offer quicker recharge and discharge times than batteries but suffer from diminished capacity. Most supercapacitors use porous carbon as active electrode materials, such as activated ...

Relatively low power applications which only operate when there is indoor light, providing sub mW power and transmitting with BLE. The supercapacitor need only be sized for the energy and power to ...

A capacitor is like a high-speed battery that can quickly store and release energy. What happens when it becomes 'super?' Researchers have potential solutions to improve energy-efficiency. Researchers ...

Sometimes the simplest hacks are the most useful ones, and they don’t come much simpler than the little supercapacitor LED flashlight from serial maker of cool stuff [Jeremy S. Cook]. Little more than ...

Lamborghini has chosen a radically different way of dipping its toe in the waters of hybridization with the announcement of its new Sián, which couples a screaming, naturally aspirated V12 engine with ...

Design teams are now eyeing supercapacitors for a range of new products in energy harvesting, office automation, backup systems, and more. These supercapacitor cells provide efficient storage that can ...

An international team of researchers has developed a supercapacitor composed of graphene and carbon nanotubes that is claimed flexible enough to be woven into clothing and potentially powerful enough ...

Researchers have developed a new analysis technique that will help scientists improve renewable energy storage by making better supercapacitors. Researchers from the University of Surrey's Advanced ...
