Researchers at the University of California, Riverside have developed a new graphene-based supercapacitor that uses a nanoscale architecture to double its energy and power performance compared to commercially-available alternatives. This breakthrough is another important step toward making supercapacitors viable for use in fast-charging, high-performance electric cars and personal electronics.  Read More

Researchers have created wires with supercapacitance, which may eventually also double as ...

We literally live in a wired world, with wires snaking hither and yon transmitting electricity and data. Many are visible, while many more are hidden in the walls of buildings, the panels of cars, and the fuselage of aircraft. Now, imagine; what if we were able to turn each and every one of these into a battery that not only transmitted electricity but stored it too? Well, two researchers from the University of Central Florida (UCF) imagined that too, and came up with a way to use nano-technology to make wires with supercapacitance that may eventually also double as batteries.  Read More

Structural supercapacitors could allow energy to be stored directly in structural material...

Imagine using a mobile phone powered entirely by its casing, or an electric car that runs off power stored in its chassis. Researchers at Vanderbilt University have created a structural supercapacitor that could, they believe, bring this closer to reality, making batteries and power cords obsolete. The structural supercapacitor could make it possible to store energy directly in structural materials, allowing them to deliver power long-term while surviving the real-life mechanical stresses they're bound to experience.  Read More

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 to offer a real alternative to batteries for use in portable devices. Capable of being charged and discharged in excess of 10,000 cycles, the new supercapacitor also promises to be significantly lighter, faster to charge, and more robust than current battery technology.  Read More

The supercapacitor-powered Helium Bluetooth speakers from Blueshift

Sharing music with friends through laptop or smartphone speakers can be less than satisfying, which perhaps goes some way to explaining the overwhelming choice of portable Bluetooth speakers that come into view as you enter a consumer electronics store. Such offerings all suffer the same problem, though. Just as you're getting your groove on, the built-in battery dies and you have to wait hours while it juices up from a wall socket. What mobile music lovers like me need are wireless speakers that can charge in minutes, and then last for hours. An impossible dream? Sam Beck from Portland's Blueshift doesn't think so. He's developed mono and stereo portable Bluetooth speakers powered by supercapacitors. Helium users can look forward to a super quick charge time, hours of full volume playback and years of recharge cycles before needing to consider a supercap refresh.  Read More

A team of researchers at the Vanderbilt University in Nashville, Tennessee has designed a supercapacitor made primarily of silicon that has shown much improved power density over its commercially available alternatives. The advance could allow for interesting integration of battery technology in everyday electronics, from solar cells to smartphones.  Read More

Monash University researchers have created a compact electrode that uses a liquid electrol...

Graphene-based supercapacitors have already proven the equal of conventional supercapacitors – in the lab. But now researchers at Melbourne’s Monash University claim to have developed of a new scalable and cost-effective technique to engineer graphene-based supercapacitors that brings them a step closer to commercial development.  Read More

The Toyota hybrid TS030 team pushed the Audi Sport Team Joest teams off the top step of th...

The battle of the hybrid racing cars in World Endurance Racing took an interesting turn this weekend when Toyota's TS030 Hybrid won the fifth round of the FIA World Endurance Championship in Sao Paulo, Brazil. The TS030 Hybrid uses a THS-R (Toyota Hybrid System - Racing) comprising a gasoline-burning 3.4 liter V8 engine and a 500 kJ Nisshinbo supercapacitor energy recovery unit which supplies power to the rear wheels. The Audi uses a turbocharged 3.7 liter V6 diesel engine with a 500 kJ electric flywheel accumulator to store recovered energy and feed it to the front wheels to create four-wheel-drive. It seems Audi has a worthy adversary in Toyota and the remainder of the season will be worth watching.  Read More

Researchers at Drexel University are developing an electrochemical flow capacitor (EFC) that combines the storage capabilities of batteries with the much longer cycle life and power output of supercapacitors. The team's goal is to improve the stability of the energy grid and ease the integration of renewable energy sources.  Read More

The TMG EV P002

Toyota Motorsport is hoping for a spectacular few months in the middle of 2012, most notably with the race debut for the TS030 HYBRID in the Le Mans 24 hour and now for an EV assault on Pikes Peak. Not content with challenging the all-conquering Audi Team Joest with its hybrid 3400 cc V8 and supercapacitor energy storage system, the company has unveiled a new development of its TMG EV P001 car (which set a very respectable EV lap record at the Nürburgring Nordschleife in 2011) dubbed the P002 with which it will compete in the Pikes Peak International Hill Climb in Colorado on July 8.  Read More
