capacitor chemistries. EEStor is using nothing new. There are a lot of
skeptics but if EEStor is right this may be what we need for our EVs.

EEStor in the news
Hi Everyone,
For those of you who are new to this list, we learn about things having to
do with electric vehicles. The reason this particular news is interesting is
that, if this ultracapacitor that EEStor claims to have works as described,
it will fundamentally change the type of energy we use for transportation.
Overnight, electricity will become the energy of choice. All internal
combustion will be obsolete and all batteries will become obsolete. It will
happen as fast as the OEMs can retool.
In short, these devices will allow near infinite recharging cycles, will
weigh a small fraction of even Lithium ion batteries, will be significantly
less expensive as any battery and can take fast charging equal to any
current available. Consider how much untapped wind power goes wasted at
night. Converting that to clean electricity to offset filthy gasoline and
diesel would literally transform our country.
On the other hand, it could be wishful thinking.
I'm of the mind it works.
I encourage you to read this regardless so you'll be up to speed on the
concept.

A New Deal for EEStor
A delayed battery technology may indeed be on the way.
By Tyler Hamilton
Earlier this month, a stealthy startup that says its
ultracapacitor-based energy storage system could make conventional batteries
obsolete took a small step toward proving its many skeptics wrong.
The company, EEStor, based in Cedar Park, TX, has made bold claims
about its technology but has so far failed to deliver a working commercial
product. However, an agreement announced this month with Lockheed Martin,
based in Bethesda, MD, suggests that the company could be making
progress--at least enough to convince a major defense contractor that the
technology has merit. The agreement gives Lockheed an exclusive
international license to use EEStor's power system for military and
homeland-security applications--everything from advanced remote sensors and
missile systems to mobile power packs and electric vehicles. The technology,
Lockheed said in a statement, "could lead to energy independence for the
Warfighter."
Lockheed has not seen a working prototype but said that qualification
testing and mass production of EEStor's system is planned for late 2008.
Lockheed would not disclose the terms of the partnership. "We fully intend
to work with EEStor this year to prototype and demonstrate this technology
for the soldier," says Lionel Liebman, Lockheed's manager of program
development in its applied research division. "We're looking at a lot of
applications where the EEStor application can help."
EEStor says that its patented system is a nontoxic, safe, and
lower-cost alternative to conventional electrochemical battery technologies,
offering ten times the energy density of lead-acid batteries at one-tenth
the weight and volume. The company also claims that its system allows rapid
and virtually unlimited charging and discharging without significant
degradation of the unit. (See "Battery Breakthrough?") But many experts have
been skeptical, citing the difficulty of working with the material at the
core of the company's system: a ceramic made of barium-titanate.
A lack of news from the company has only fed the skepticism. The last
public announcement from EEStor came last January, when it revealed that it
had made high purity barium-titanate powders on its first automated
production line. But the company has so far failed to deliver units of its
storage product to minority investor ZENN Motor, a company based in Toronto
that plans to use it in electric vehicles. Originally, the devices were to
have shipped in the first half of last year.
EEStor chief executive Richard Weir declined to comment on the
development of the technology and the agreement with Lockheed. But he told
Technology Review in an e-mail message that he's anticipating another
"technical news release in the near future," at which time he would be open
to discussing EEStor's progress in more detail.
ZENN chief executive Ian Clifford remains optimistic. "Every
restatement of delivery time has been for good reasons," he says, suggesting
that the Lockheed announcement and the due diligence that led to it "add
credibility to the technology." He's now expecting delivery of the
energy-storage unit in mid-2008. And it won't be a prototype, he emphasizes:
it will be a mass-produced commercial product. "This is about
commercialization, not hitting technology roadblocks. We're in constant
contact with EEStor, with regular visits to their site. We always come away
from every meeting much more excited that this is going to happen."
ZENN has already switched to a different motor in its current
low-speed electric vehicle, partly in anticipation of the new energy storage
technology. "We're first in line," says Clifford. "We understand we'll be
taking the first product off the production facility being built right now."
Liebman, who says that he has visited EEStor's facility in Cedar Park
and was impressed, also expressed confidence in the company. He notes that
EEStor's approach so far allows for a rapid ramp-up in production. "I think
it's very real," he says.
