Electronics

Micro-supercapacitors store energy directly inside a chip

Batteries are getting better at a steady pace, but the technology is far from perfect – they are still quite short-lived, and have real trouble delivering bursts of power. Now, researchers at Drexel and the Paul Sabatier universities have managed to embed mini supercapacitors directly inside a microchip to enable electronics that are even smaller, last longer, and have more power to feed on.Read More

Rechargeable paper sheets could help rewrite the book on electricity storage

Using millions of tiny fibers of nanocellulose sheathed with a conductive polymer coating, scientists have created sheets of paper that can store significant amounts of electric charge. Dubbed "power paper," the material is able to be recharged many hundreds of time, and in mere seconds. It is also lightweight, requires no toxic chemicals or heavy metals to create, and may offer a renewable and prolific way to provide energy to all manner of devices.Read More

New device combines the advantages of batteries and supercapacitors

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

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.Read More

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

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.Read More

Supercapacitor-powered Hydrogen speaker offers five minute charge time

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.Read More

Cigarette butts transformed into high-performance supercapacitor component

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.
