EEStor ultracapacitor

[vanilla ice]

EEStor's new slogan, "Supercaps. Come get some!"

 

[tostino]

Oh very nice, DN:F reference... Look at the date on that magazine, 1997!!! They are still saying it is coming very soon, and it's nearly 2010 lol.

EEStor CEO Tells All in Leaked Phone Call:
http://www.democraticunderground.com/discuss/duboard.php?az=view_all&address=115x202946
Highlights :

The supercapacitors can be produced cheaply with off the shelf hardware.

Projected price is $100-150/KWh

They will be UL listed (i.e. very safe)

Will be producing prototypes in volume by Q4 of this year. [ that is 2009]

 

[ahambone]

There is nothing new here. This is all the same smoke and mirrors from July 2009. Wake me up when a prototype on a test bench is photographed or videoed with monitoring equipment showing that it works. Until then this is snake oil from the ocean-front district of Utah. :wink:

Here's a report about Ultracapacitors. Surely it must have something about EESTOR in it at that price?
http://theenergycollective.com/TheEnergyCollective/58048
Only $1995!!!!

The eestory is a blog I have been following for years but it is getting kind of ridiculus. All the sensible people have shut up and are simply waiting while the fanatical believers and nonbelievers fight it out. :lol:

The layers now being produced have very small internal self-discharge and crossover losses. These layers have been cycle tested by EEStor and have achieved over 1 million full cycles at a rate of less than 30 seconds per cycle. Each cycle consisted of charging to 3500 volts followed by discharging to zero volts. The EESU layers have better self-discharge characteristics and lower losses in the charge/discharge cycles than other known competitive energy storage technologies

And those are just the ones that spelled it right.

OMG are they seriously not dead yet? These things have been vaporware for YEARS. As much as I want to see it happen, it's a unicorn.

I'm eager to use them in my jet-pack and levitating car.

LOL I am not holding my breath. Just thought Id post an update, take it or troll if you like.

However. Lipo was never for me bwecause they expode, and the Lifpo4 process was rather dicey for a cost effective solution with long series packs until good BMS and parts for the became common. Same could be said about e-vehicles in general for 50 years, even now some people think it's unreliable, those damed halls can be unpredictable. or else we are using DC brushed motors, YUK..

These products are NOT suitable for protection against personal injury.To AVOID personal injury or death, DO NOT USE these products as emergency stop or safety devices, or in any other application where human safety is at risk.

Opps.

Many of us are a dangerous in reality, but we are getting there slowly but surley. Be in denial about this but you should know better.

http://en.wikipedia.org/wiki/Lithium-ion_battery#History

Lithium batteries were first proposed by M.S. Whittingham, now at Binghamton University, while working for Exxon in the 1970s.[14] Whittingham used titanium(II) sulfide and lithium metal as the electrodes.

LiFePO4 was discovered by John Goodenough's research group at the University of Texas in 1996

Ohh the answer was NIMH for how many years "NOT"

The first consumer grade NiMH cells for smaller applications appeared on the market in 1989

The UltraCaps time frame dosent look so bad. I think 2006 and 6 years, Wow not so long guys. Patience, patience now.

Any one held there breath ever for a good safe battery technology with a good energy density yet?. Besides you cant hold your breath for a 150 odd years.

^^Fanbois^^

Whats funny here, is they are not claiming to have made a high voltage ultra-cap at all. They are claiming a single layer high voltage cap with low self-discharge. Whoppie do-da. I made low self-discharge high voltage single layer capacitors with tin-foil and sheets of polyethylene garbage bags when I was in 7th grade making Tesla coils... You can't get energy-storage-meaningful-capacitance from single layer caps, and anyone can make them as high of voltage and as low of self-discharge as they like, just by using a thicker sheet of plastic between the foils.

The claim EEstor made about getting useful energy storage involved having high voltage ELDC's, which can hold about 1000x higher capacitance per unit volume than single layer caps, because they use an electrolyte to wet into the pores of extremely high surface area carbon to store energy and act as the current path rather than just electro-static storage like a single layer cap.

 

[TylerDurden]

What I find the biggest problem with supercaps is the linear voltage drop. Good batteries have a very nice plateau during discharge, followed by an easily identified roll-off at the end of capacity. Perfect for EV applications, IMO.

Comparing the recent development of caps vs. the recent development of batteries (graphene tech in particular); I'll stick with batteries being the future.

 

[317537]

Thank you Tyler for the respectable reply.

The magic discovery that EEStor are claimng is there high farad cap backed with a very high voltage storage capability, storing more energy than capacity then down converting the energy into current.. I ,would agree that there are a lot of skeptics, but they claim that these caps are capable of storing 3.7kv, this is rather high and quite dangerous, and more so when paired with the farad they need to store, but no more dangerous than petroleum Id imagine..

I read they have the DC converter capable now, it's just a matter of time to iron out the bugs and make it safe..

The consumer will not be seeing 3.7lkv at the power plugs, my guess the caps will be sealed well away and fused circuit breakered at 100 amps more or less.

If and when we will see this invetion hit the shelves, it will come with the converter built in. The caps are said to be cheaper to make than lithium cells, but the cost will come into the quality of the PSU its paired with.

The above comments beiore Tyler, reminds me of when an upstart company made claims of building a laser TV, it, was wall to wall flame and fire comments that it was vapourware, its a fraud, its dangerous, the comapany is broke, to the point it almost destroyed the invention by placing disrepute onto the company who invented it.. I never listened, and no one should listen to troills who are following others with invested interests,. But I still a wait for a Laser TV to come out smaller than 73"


It angers me when the pitch forks and torches crew can put risk to the sucess of innovatiion. Pitch forks and torches, if the shoe fits?,


One last comment for the doubters who troilled the laser tv. http://laservuetv.com/

I will say the same about the ESU pretty soon touch wood..

 

[amberwolf]

AFAIK, in this case it is EESTOR themselves that have been shooting themselves in the foot, by "coming soon" information releases since the beginning, and not carrying thru with that.

If they marketed a very basic version of the product, then improved on that, and so on, perhaps it would be easier to believe in the eventual existence of a full-capability unit.

 

[liveforphysics]

It would be great if EEStor could release a product, but it's sadly impossible to have a double-layer high voltage cap, if the solvent can function as a double layer cap needs the solvent to function for it to operate, the solvent will disassociate and rapidly off-gas the moment the voltage goes above ~5v.

What they could potentially have is a higher energy density high voltage single layer cap, but it will be off a few orders of magnitude in energy storage density from a double layer cap, and hence not be meaningful for EV energy storage.

317537,

You should be ashamed of yourself for bringing up this stock scam on ES once again. I know some of us almost fell for it back in 2009, and I'm sure a few members actually did lose money on it. Based on your current and past posts on the subject, you obviously aren't just an interested unrelated 3rd party with no skin in it. Are you one of the Believers still hoping to cash that lottery ticket someday, or are you one of the core group who have made a killing with the scam which isn't illegal due to the convoluted ownership structure of the companies involved. It's quite slick the way it was done, but enough is enough already.

John

I'm guessing CAEL is the one running that website (which is misspelled...I wonder why they couldn't have used the correct word in the URL instead of "concered", when they created their site. ).

There is a fraud going on and you are interested in a misspelled URL??? :wink:

Back to the fraud. EESTOR made claims in 2004 patent applications (now issued patents) but cannot back them up as of 2012 (eight years later)-- let alone as of the time the claims were originally made. The likely correct technical legal term is inequitable conduct against the patent office by the filing attorney for EEStor. As for inventor Weir, it is likely technical perjury (a sworn but false statement concerning the patent application).

NanoCarbons has documented the fraud in this document.

We've already figured out long ago that they're not what they say they are, so at this point most anything different could be interesting. (and I tend to be interested in lots of bits all at the same time, with the oddest minutiae being what I might be most likely to comment on).
