Cedar Park, Texas-based EEStor today announced two independent certifications of its energy storage technology, coincidentally the same day competitor Maxwell Technologies announced a licensing deal (see Golden Dragon Bus to use Maxwell ultracapacitors.)
Secretive EEStor's 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.
And Ian Treviranus of HORIBA Instruments said the company's technology helps maintain sufficient voltage at ideal temperatures, according to EEStor.
EEStor is developing solid-state storage technology that company officials say reduces the size and weight of energy storage while increasing the lifespan and power.
Today's announcements give some credibility to EEStor's processes. The company has operated in stealth since beginning work on chemical purification and powder production in 2007.
The industry has already taken note of EEStor, which has licensed its technology to automobile and defense customers.
Toronto, Ontario's Zenn Motor Co. (TSX: ZNN) has purchased the rights to EEStor's batteries for the automobile industry. Zenn plans to use the batteries in electric cars starting in fall 2009 (see Zenn gearing up for EEStor-powered car).
In January, Bethesda, Md.-based Lockheed Martin (NYSE: LMT) announced an exclusive licensing deal to use EEStor's ceramic battery chemistry in military and homeland security applications (see Lockheed Martin to use EEStor's ultracapacitors).
EEStor officials could not be reached for comment. Also today, the company announced it filed a patent application for its technology to polarize ultracapacitators.
Zenn CEO Ian Clifford said in March that EEStor's production line was nearing completion.
Zenn invested $2.5 million to secure a 3.8-percent stake in EEStor in April. Kleiner Perkins Caufield & Byers reportedly invested $3 million in EEStor in 2005.

ultracapacitor industry
Submitted on July 31st, 2008 by Carl (not verified)Pollution: Moving from individual engines to central electricity generating plants would mean a net decrease in overall pollution. Even getting pollution out of our crowded cities would be a gain for public health.
United States, Japan and Russia currently lead the global ultracapacitor industry, with makers such as Maxwell Technologies Inc. and NEC Corp. occupying the majority of world market. To keep up with their foreign counterparts, mainland China makers are upgrading their production technologies and improving their product quality and R&D.
Dick Weir, founder and CEO of EEStor, told me a few weeks ago that there would be an announcement soon on permittivity of its barium titanite powder, considered a major benchmark that would trigger future payments to EEStor from ZENN, and I can only assume Kleiner Perkins as well.

Is the world ready?
Submitted on August 2nd, 2008 by Caroll (not verified)I have been watching Eestor for over a year. Of all the positive and negative comments I have read in the past the only thing I would like to say is technology like this doesn't happen overnight but when it does watch out. I am sure the original price I've heard for an Eestor in a 25 KWhr size is probable low but even twice the original price puts it's cost per KWhr is way lower than any of the Long life batteries. They first published a cost of $3,100 for a 54 KWhr pack when mass produced. That was probably way overly optimistic but solid state mass production does have some history of really getting cost down.
This is more positive news. All us EV fans can do is hope and wait.
Why is Eestor Being So Secretive?

Why is Eestor Being So Secretive?
What is being verified?
Submitted on January 2nd, 2009 by Excoriator (not verified)Process? Equipment? What in the world is the use of that?
The central problem is that Barium Titanate's permittivity falls with voltage, so the thing cannot work. They claim they've found a workround, but are unwilling or incapable of demonstrating it.
Not long ago they announced that the purity of the Barium Titanate had been independently verified - a similarly entirely irrelevant announcement. They will be announcing soon that their chairs have four legs!
They have been running for nearly nine years now, and still no prototype.
