EEstor is a company based in Cedar
Park, Texas, USA. A start up company pioneering a new energy storage
"will change everything"
dramatically outperform the best lithium-ion batteries on the market in

implications are enormous...
EEStor's EV Ultra-Capacitor
breakthrough has the potential to radically transform a transportation
sector already flirting with an electric renaissance.
A superior type of supercapacitor, using barium titanate
coated with aluminum oxide and glass, to achieve a level of capacitance
much higher than what is currently available in the market. A high
energy storage device that will be superior to current chemical
batteries. Richard Weir is CEO and President, as well as the inventor. A
five-minute charge costing $9 would give the battery enough energy to
drive a small car 500 miles. Toronto, Canada-based Feel Good Cars, which
operates Zenn Motor has invested $2.5 million in EEStor. EEStor is
backed by VC firm Kleiner Perkins Caufield & Byers, and the company's
founders are engineers Richard Weir and Carl Nelson.

accomplished with special charging stations which have much higher
voltage than 120 V.

Just about anyone who has ever considered buying an electric
vehicle (EV) and then decided against it cites one fact — and one fact
alone — that caused them to rethink the idea. Range. The inability to
drive long distances without enduring a five- or six-hour "refuel" has
kept many of us out of the EV market. EEStor, a privately held Cedar
Park, Texas, company dedicated to the design and manufacturing of
high-density storage devices, has taken a major step forward in
eradicating this problem.
Those long charging times result from the fact that most EV power
systems rely on lithium-ion batteries, which take time to charge.
Quick-charging the packs is possible, but this will result in shorter
battery life. Neither way works well for the consumer. So the folks at
EEStor decided to turn away from traditional battery systems and look
toward capacitors, power storage devices that rely on two charged
terminals separated by a non-conductive material called a dialectric.
There has been speculation all over the Web these past few months that
EEStor had finally "cracked the code" and created an ultra-capacitor
that is better than a lithium-ion battery cell in almost every way. It
seems that the company has finally done so: On January 17 EEStor
announced third-party verification of the dialectric powders needed to
make these capacitors.
"This is a very meaningful milestone in terms of production of an
ultra-capacitor for use in electric vehicles," noted Ian Clifford, CEO
and founder of Zenn Motor Company. Zenn is an electric vehicle producer
that holds exclusive rights to use this new technology in vehicles up to
2,645 pounds curb weight, roughly the same as a Honda Accord or Toyota
Prius. "It will allow for the commercialization of high-range,
high-speed vehicles for mass production," he said, finally making these
cars a reality for the general public.
Clifford pointed out that there are presently more than 40 million cars
worldwide that fit this weight specification, so the potential uses for
this technology are huge. Zenn expects to receive the first capacitor
units by the end of the year and will have them in its NEVs
(Neighborhood Electric Vehicle, meant for around-town driving) by the
middle of next year. Zenn is also developing a vehicle using the new
capacitors that will be capable of highway speeds and meets all highway
safety standards. It is actively seeking dealers to partner with
throughout North America.
Unlike regular lithium-ion battery cells, the EEStor ultra-capacitors,
or EESUs as they are called, are lighter, more versatile and can be
charged and discharged up to a million times.
"To put this in perspective," says Paul Scott, co-founder of Plug In
America, "I drive an electric Toyota RAV4 with a 1,000-pound battery
that is capable of holding 27 kWh (kilowatt-hours) of power. I could
replace my battery with three EESUs, weighing a total of only 300
pounds, that are capable of holding 45 kWhs of power." The additional
power and reduced weight would more than double the vehicle's 120-mile
range and it would recharge in a matter of minutes off 220 volts,
slightly longer when using household 110 volts.
What's more, the EESU power system would not need to be replaced for
well over a million miles. If replacement were to ever occur, the units
are fully recyclable, and unlike batteries, contain no environmentally
harmful compounds, according to Richard Weir, EEStor's president and
Electric vehicles may have a long way to go in terms of availability and
popular acceptance, but with the announcement of EEStor's breakthrough,
range will no longer be an issue. With this new technology in place, an
all-electric vehicle that is simpler, more efficient and less expensive
than a comparable gasoline car may be right around the corner. If Zenn
has its way, you'll be able to pick up one of the company's cars at your
local dealership, hop in, and drive it cross-country without stopping
for longer than it takes to grab a bathroom break and a cup of joe.
