New device combines the advantages of batteries and supercapacitors

By - April 19, 2015 2 Pictures
Scientists at UCLA's California NanoSystems Institute have developed a new device that combines the high energy densities of batteries and the quick charge and discharge rates of supercapacitors. The hybrid supercapacitor is reportedly six times as energy-dense as a commercially available supercapacitor and packs nearly as much energy per unit volume as a lead-acid battery. Read More

Silk-derived material could boost battery performance

By - March 12, 2015 1 Picture
Next-generation lithium-ion batteries may hold more charge for a greater number of cycles thanks to a new material derived from natural silk. Scientists at the Beijing Institute of Technology found that not only does their regenerated silk fibroin material work for over 10,000 cycles but it also stores five times more lithium than graphite, which is the most common choice for the anode (negative electrode) in lithium-ion batteries.

New tech could allow electric cars' body panels to store energy

By - November 11, 2014 1 Picture
Imagine opening up an electric car and finding no batteries. An absent-minded factory worker or magic? Perhaps neither. If nanotechnology scientists led by the Queensland University of Technology (QUT) are on the right track, it may one day be a reality as cars are powered not by batteries, but their body panels – inside which are sandwiched a new breed of supercapacitors.

Supercapacitor-powered Hydrogen speaker offers five minute charge time

By - November 4, 2014 3 Pictures
Rechargeable batteries are the Achilles heel of portable electronics, requiring hours to recharge and generally having a life of around 1,000 recharge/discharge cycles before charge capacity starts to fall noticeably. To avoid both these problems, Sam Beck from Portland, Oregon-based Blueshift has created portable Bluetooth speakers that can be charged within five minutes and boast rated lifetimes of 500,000 charges thanks to being powered by supercapacitors.

Hemp-derived carbon nanosheets help build cheap, high-performance supercapacitors

By - August 20, 2014 1 Picture
Using waste hemp fibers as the starting material, researchers at the University of Alberta in Canada have developed a high-performance electrode material for supercapacitors at one thousandth the cost of the more commonly used graphene. The advance could lead to supercapacitors that are both cheaper and able to operate under harsh environmental conditions. Read More

Cigarette butts transformed into high-performance supercapacitor component

By - August 6, 2014 1 Picture
Billions of cigarette butts are discarded around the world each year and, even when disposed of properly, pose a threat to the environment by leaching arsenic, lead and other nasty chemicals into land and waterways. New research shows these butts could be set for a new lease on life, with a team of Korean scientists demonstrating that used cigarette filters could actually double as a highly-effective energy storage material.

High-performance supercapacitor doubles performance of commercial alternatives

By - June 9, 2014 3 Pictures
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 create flexible wires that could double as batteries

By - June 4, 2014 1 Picture
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.
