Get Ready For the Super Ultra Capacitor
April 29, 2010 | 5 Comments
The latest news in energy storage has Drexel University with a new piece out that notes in a paper published in Science by John Chmiola doubling supercapacitors storage and then MIT Technology Review marking it up to triple. It’s a little amusing, yet Chmiola is on to something. Chmiola idea is to use an electrode [...]

Ultracapacitors Ready for Power Storage
April 19, 2010 | Leave a Comment
When you couple ultracapacitors with lithium batteries performance of an electric vehicle is dramatically boosted. Ultracapacitors give electric vehicles the instant response needed to get going, recover braking energy, work across a wide temperature range, and charge very quickly for thousands or millions of cycles. There is more out there than Eestor, and some are [...]

Understanding Digital Quantum Capacitors
December 24, 2009 | 3 Comments
To start, lets get the digital quantum battery misnomer out of the way. What’s being discussed here and other places isn’t about battery building; it’s about a theoretical construction of a nano-sized capacitor. It’s interesting as the storage medium isn’t like a conventional capacitor with the material between the anode and cathode holding the energy. [...]

Making the Most of Your Energy Density
September 9, 2009 | 2 Comments
Some studies have demonstrated that a simple parallel connection of an ultracapacitor to a low-cost alkaline battery can duplicate the performance characteristics of a lithium-ion battery. Now on the market is an ultracapacitor kit for forklifts using lead acid for the energy density storage and Ioxus ultracapacitors for the power density. Better yet in many [...]

EEStor Signs a Major New Contract
August 31, 2009 | 5 Comments
EEStor, the now famed ultracapacitor maker of the future is one step closer to having a product coming to market. Last week saw information escape that EEStor has contracted with Polarity of Rancho Cordova, California to design and specify the construction details of the ultracapacitor’s power converter. A power converter would ideally provide a combined [...]

A Combined Capacitor and Battery Technology From Japan
June 19, 2009 | 1 Comment
The Japanese firm Eamex Corp. of Osaka announced Monday June 15th 2009 that the energy density per unit volume of its capacitor currently under development has been enhanced up to 600Wh/L. That’s enough to snap around one’s attention. According to the company the value 600Wh/L is equivalent to the energy density of a lithium-ion secondary [...]

Is There Joy at EEStor That Supports Zenn?
May 1, 2009 | 2 Comments
The mystery guy at bariumtitanate.blogspot.com follows the EEStor trail with considerable determination and more than a dab of good sense. Last week saw Zenn, the Canadian mini car manufacturer, who is in for an investment in EEStor, plus more when certain milestones are met had an announcement of sorts out that sent their stock off [...]

A Ultracapacitor Built From Carbon Nanotubes and Nanowires
April 3, 2009 | 2 Comments
Chongwu Zhou of USC describes a line of prototype devices built from metal oxide nanowires with carbon nanotubes in a newly published paper titled “Flexible and Transparent Supercapacitor based on Indium Nanowire / Carbon Nanotube Heterogeneous Films” in the journal Applied Physics Letters (Vol.94, Issue 4, Page 043113, 2009). The research continues a line of [...]
