Penn State Offers A New Ultra Capacitor Design

August 25, 2016 | 1 Comment

Penn State Materials Research Institute scientists have developed a polymer dielectric material with high energy density, high power density and excellent charge-discharge efficiency for electric and hybrid vehicle use. The key is a unique three-dimensional sandwich-like structure that protects the dense electric field in the polymer/ceramic composite from dielectric breakdown. The team’s results have been […]

EEStor Looks To Be Closer To Market

December 24, 2014 | 3 Comments

Over the past few days EEStor and the company holding better than 70 percent of its ownership, Zenncars, have released an independent test of it composition modified barium titanate ultracapacitor powders. The interest is increasing because Intertek Group Plc (“Intertek”) rigorously tested an extensive sampling of EEStor capacitor layers across multiple voltages (250vdc, 450vdc, 700vdc, […]

EEStor Lives!

February 11, 2013 | 6 Comments

Now two weeks out from a press release EEStor has met the goal of getting under the radar of the media.  A quick look at Google News finds almost nothing.  Still, the stockholders of Canada’s Zenn Motors are thrilled.  Zenn is a “hibernating” company now, as its electric car building has long since ceased.  The […]

EEStor Makes a Little Bit of News

March 29, 2012 | 4 Comments

The Bariumtitanate.blogspot, which is a close observer of the EEStory as they’re calling it over there, found a bit of news on the EEStor saga. Zenn, the motorcar company that took off thinking that the EEStor ultra capacitor was coming soon survives with essentially nothing for sale of note.  But the capital base has a […]

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 […]
