High-Temp Ultracapacitor Developed at NPL Could Benefit EVs

Benji Jerew — Wed, 07 Aug 2013 18:57:45 +0000

Electric vehicles can really put electrical and electronic systems to the test, requiring high voltage and high power components that will deliver performance without destroying themselves. In general, alternating-current [AC] electric motors deliver better performance than direct-current [DC] motors, depending on the application. On a factory floor, for example, a three-phase AC motor doesn’t require […]

Niobium Oxide-Based Supercaps Could Replace Batteries

Ovidiu Sandru — Tue, 16 Apr 2013 19:17:44 +0000

Researchers from University of California (UCLA) discovered new supercapacitors based on niobium oxide, which will be able solve the problem of energy storage and availability in both batteries and normal capacitors. This new discovery, published in the Nature Materials Journal, can lead to a whole new generation of supercapacitors that are able to store and […]

For years, people have been thinking to reduce or even eliminate gasoline-powered vehicles, and switch to battery-powered ones. The the battery-powered electric vehicles' era hasn't already begun well enough, and now some are even thinking to replace batteries with something else: ultracapacitors.

EnerG2’s New Activated Carbon Electrode Cuts Ultracapacitor Cost in Half

Ultracapacitors are currently being used in applications that need high amounts of electricity in short times. Unlike conventional batteries, which can store much more energy but release it slower, ultracapacitors (or sometimes called supercapacitors) can survive for longer, because they don't use the same chemical processes.

Chevy Volt to Use AFS Trinity's Ultracapacitors for Better Acceleration / Regenerative Braking

Hybrid and electric cars both have regenerative braking systems, which transfer the energy otherwise lost as heat back into electricity, by switching the motor's function from its normal one into an electricity generator when the driver pushes the brake pedal.

New Method of Making Supercapacitors on Thin Films Improves Price and Capacity

Ovidiu Sandru — Fri, 23 Apr 2010 19:20:45 +0000

Supercapacitors are energy storage devices that can be recharged for virtually unlimited times, but the amount of energy they store is limited. Their working principle is not based on chemical reactions, but rather on transferring surface charges.

Ultracapacitors Made of Bulk Glass Tripled Their Storage Capacity

I guess I don't have to emphasize the importance of batteries in an electric car economy of the future. I also don't have to tell anyone that many manufacturers pursue making ultracapacitors for their ability to quickly charge, discharge, and store a huge amount of energy - the perfect combination for an on-the-fly highway recharging.

New Supercapacitor Can Give 1MW/kg/sec of Electricity

Ovidiu Sandru — Wed, 18 Mar 2009 16:35:42 +0000

If we pursue the road towards the full electric car, we must find ourselves the energy storage that can bear at least the power of gasoline. As far as today, batteries, supercapacitors and hydrogen have been the ways to follow for powering an electric car. Of the three, the supercapacitors have a great advantage: they can charge and discharge very quickly, giving instant torque to the electric car's motor.

New Graphene Layer to Double Ultracapacitors Storage Capability

Ovidiu Sandru — Tue, 16 Sep 2008 18:18:52 +0000

Engineers and scientists from the University of Texas at Austin, led by Rod Ruoff, a mechanical engineering professor and physical chemist, have created a one-atom thick layer of carbon, called "graphene", and they put it to use in electrical storage systems, such as ultracapacitors, a viable way to clean and efficient energy storage.
