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.  [...]

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 applications, [...]

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 [...]

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 battery. [...]

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 [...]

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 prototype [...]

An economic slowdown has a way of focusing attention. The ultracapacitor or supercapacitor field is a growing one for an important reason. The carbon tax, or “carbon cap and trade” to throw off the unthoughtful, is having an impact on long term planning. The Obama administration has floated income to the government of $600 billion [...]

The popular and news making EEStor has a competitor coming. EEStor, now famed for their secrecy about what goes in their capacitor, leaves lots of room for speculation. Of note is they have gained more credibility over the years and seem closer to delivering product.
The ultracapacitor field is based on simple, or as simple as [...]

Carbon laid out in a one-atom thick layer making a structure called “graphene” is being lab tested as an ultracapacitor by mechanical engineering professor Rod Ruoff at the University of Texas at Austin. Ruoff says, “Through such a device, electrical charge can be rapidly stored on the graphene sheets, and released from them as well [...]

This week saw EEStor CEO and president Richard Weir, who is also a co-inventor, announce that its processes and equipment have apparently been verified by Ed Golla, lab director of Texas Research International, a multidisciplinary research, development and testing company in Austin, Texas. EEStor added that Ian Treviranus of Horiba Instruments says the company’s technology [...]
