Tree Waste Found to Make Good Super Capacitors

October 24, 2013 | 2 Comments

Research engineers at the Illinois Sustainable Technology Center at the University of Illinois (UI) find wood biochar supercapacitors can produce as much power as today’s activated-carbon supercapacitors at a fraction of the cost.  The report noted that the wood bio-char would be sourced from forest products waste, an environmentally friendly source to make power storage.

Build a Super Capacitor with a DVD Burner

March 19, 2012 | 1 Comment

The insightful and clever folks at UCLA have used a standard LightScribe DVD optical drive ($25+ and up at Newegg.com today) to produce a new type of capacitor electrodes that not only maintain high conductivity but also provide higher and more accessible surface area than conventional electrochemical capacitors (ECs) that use the typical activated carbon […]

More Than Doubling the Power In a Capacitor

October 3, 2011 | 5 Comments

With super and ultra capacitors and EEStor still far too expensive, not available if not simply vapor – capacitors need something to perk up the storage market. Dr.  Xie Xian Ning from the National University of Singapore’s (NUS) Nanoscience and Nanotechnology Initiative has developed the world’s first energy-storage membrane promising greater cost-effectiveness in delivering energy. […]

Competition for EEStor With Activated Graphene

May 13, 2011 | 4 Comments

U.S. Department of Energy’s Brookhaven National Laboratory scientists Dong Su and Eric Stach have helped to uncover the nanoscale structure of a novel form of carbon, contributing to an explanation of why this new material acts like a super-absorbent sponge when it comes to soaking up electric charge. The excitement is about a new material […]
