Zenn Motor Releases Testing Report on its Capacitor Technology (EEStorrFanFib)

Good day disruptive technology enthusiasts.

I’ve waited 6 years for this day.

Zenn Motor / EEStor released testing results and cap industry expert commentary today on their new, valuable capacitor technology.

The reports are available for viewing at http://www.zenncars.com or at http://www.eestor.us.

These materials are also available for viewing at http://www.sedar.com.

Here’s an excerpt from a press release by Zenn Motor Company:

Intertek Group plc (“Intertek”) rigorously tested an extensive sampling of EEStor capacitor layers across multiple voltages (250vdc, 450vdc, 700vdc, 1000vdc and 1500vdc) using its own equipment and testing protocols. In addition, a 250vdc, six-layer injection molded part was fully tested to demonstrate the performance and stability of an assembled multi-layer part.

Key highlights and findings of the Intertek report include:

1. Capacitance remains constant across multiple voltages and frequencies.
2. A sampling of commercially available Aluminum Electrolytic capacitors hi-pot tested to approximately 32% above rated voltage, whereas EEStor parts in the same voltage range tested to approximately 112% above the rated layer voltage.
3. Leakage current is better than tested commercially available Aluminium Electrolytic (AE) capacitors.
4. EEStor capacitors are non-polar and show the same capacitance or resistance regardless of polarity.
5. All EEStor samples were charged in milliseconds without any noted degradation of performance.
6. As the comparative data illustrates, the cumulative effects of the layered EEStor part appear to be well beyond the simple additive values.
7. The layered EEStor part is injection molded in polypropylene to ensure a full hermetic seal.
8. The resistance and capacitance levels of the dried high voltage parts indicate exceptional performance and provide for additional volumetric efficiencies over parts compromised by humidity.
9. Volumetric benefits of EEStor’s technology are seen throughout the voltages tested and become even more apparent at higher voltages.
10. The EEStor capacitor technology is significantly smaller than incumbent technology with similar
performance characteristics.
11. Hi-pot testing indicated up to the following volts per micron capacities of the EEStor parts at
these voltages:
— 250VDC: Hi-pot value of 930VDC/thickness of part tested (13 microns) = volts per
micron of: 71VDC
— 450VDC: Hi-pot value of 1130VDC/thickness of part tested (14 microns) = volts per
micron of: 81VDCo 700VDC: Hi-pot value of 1360VDC/thickness of part tested (18 microns) = volts per
micron of: 76VDC
— 1000VDC: Hi-pot value of 1890VDC/thickness of part tested (22 microns) = volts per
micron of: 86VDC
— 1500VDC: Hi-pot value of 2440VDC/thickness of part tested (29 microns) = volts per
micron of: 84VDC

Ian Clifford, Founder and CEO of ZENN and the President and CEO of EEStor stated: “The independent
testing by Intertek represents an important validation of the potential of EEStor’s technology for capacitor
applications and confirms internal testing results achieved by EEStor. The Company and its stakeholders
will benefit from the comprehensive protocols and procedures developed by Intertek at its facility in
Dallas, Texas to ensure that the test results are complete and accurate. The work took several months to
complete, and now allows the Company to begin to pursue commercial partnerships based on the
independent data and comparative testing against existing incumbent technologies.”

    Let’s start a lottery with three variables, LENR or EEStor first on-shelf, closest-to- date, pick which and date. Ante-up to me, $1 per entry.

  • Charles

    Hmm. LENR, EEStor, Permanent Magnet Motors, Roehner Papp machines, imagination.

  • Charles

    When will they be on the shelf at Lowes, Home Depot, Wal-Mart, ?Radio-Shack?, etal

  • EEStorFanFibb

    Hope you had a chance to listen to the Zogbi conference call.

    Recently, another section has been added to the EEStor.us website. A Q&A section. http://eestor.us/q_and_a.html Check it out.

    In there they state categorically that they HAVE NOT given up on commercializing an energy storage device.

  • EEStorFanFibb

    Hey EEStor curious folks… give this Zogbi interview a listen. Very interesting to say the least.

    Is there anyone who can help to evaluate these specs. Over at the eestor forum, where they have been debating and discussing for years, there seems to be a feeling that these results, while perhaps impressive, are not in the same ballpark as what Weir seemed to have been promising.

    It would be useful to have some folks who would evaluate this here for us (sorry, I should have kept some links but I did not).

  • Doug Cutler

    EEStorFanFibb, we’ve established that barium titanate forms the charge holding dielectric layer in the ESSU ultracap but do you happen to know what material they use for the conducting plate?

  • psi2u2

    A very timely point.

    • Andre Blum

      I was also a daily eestory follower years back, and gave up due to lack of progress. It left behind a sour taste, that, I admit, was always in the back of my mind and spoiled the fun a bit when following Rossi.
      So, if that miracle was true after all…

      • psi2u2

        It appears that the new specs are not nearly as impressive as originally promised, but the milestone is still significant and a breakthrough. So both the skeptics and the optimists, it seems, were partly right. At present I’m not sure its a miracle, but it is clear progress.

      • psi2u2

        Looks like not quite so much of a miracle, but at least serious progress.

  • Gerard McEk

    I would like to see a commercial product that proves the claim of 700Wh/liter. That would for me the big bang.

    • psi2u2

      Gerrard, as I seem to recall from my days reading the Eestor blog forums, I think the plan was pretty well developed along the lines of your second suggestion. As I say, this is a bit of a vague memory that I wouldn’t even have remembered except for your question – but I think that is the way they are planning to deal with the short-circuit problem.

  • Doug Cutler

    I’m not a techie but I was following EEstor for a while a few years ago. I might be able to help . . . a little. I least I’m unable to overwhelm with tech lingo.

    The first point is the EEstor technology is not a battery per se but a capacitor – or as touted a SUPERCAPACITOR. Like chemical batteries capacitors also store electrons but typically in tiny amounts. But they have an advantage over chemical batteries in that they can release their energy with much greater speed or “power”. They can also charge very fast and often have extremely large charge/recharge life cycles vastly exceeding those of chemical batteries. Yet another advantage is they can be highly stable over extreme temperature ranges.

    EEstor caused a lot of interest a few years ago claiming they could make capacitors out of super thin sheets of graphite coated with super pure barium titanate as an insulator. (The main guy behind EEstor had long experience developing chemical coatings for CDs and similar tech.) EEstor claimed previously unimagined capacitor energy densities equal to maybe 4X that of the lithium batteries of the day – thus the term supercapacitor. Combined with the other obvious advantages of capacitors like long life span and quick charging it was thought that EEstor could be the technology that would finally thrust EVs into the automotive mainstream.

    But then their progress just seemed to stall out for 2 or 3 years and a lot of people just wrote them off. Now it looks like they may be back! What seems to be missing in the article are numbers relating to the all important energy density. Is 4X lithium energy density confirmed or not? I’m not sure. Someone more tech savvy than I will have to do that analysis.

    • EEStorFanFibb

      I’ve been following EEStor closely for years and I don’t recall EEStor every using graphene but the super pure barium titanate powder is bang on. High Energy Density is still a goal of theirs. But they aren’t revealing their current progress in that area yet. I think they will succeed and there will be a new awesome EEStor energy storage device on the market someday. Time will tell. Meanwhile disruption of capacitor markets is totally in play.

      • Doug Cutler

        OK, if you insist I’ll actually look up some facts this time . . .

        Barium Titanate is the dielectric component of the EEStor capacitor with dielectric defined as: “a substance in which an electric field can be maintained with a minimum loss of power,” also “An electrical device consisting of two conducting plates separated by an electrical insulator (the dielectric), designed to hold an electric charge.”

        I had it in my head that the barium titanate covered the charge holding material but I was incorrect – so no graphite or graphene or whatever. My apologies.

        Here are a couple of other corrections: the term applied to an extremely high energy density capacitor is not supercapcitor but ULTRAcapacitor. And, EEStor is the company but the name of their ultracap tech is called EESU.

        Hope THIS helps.

        • psi2u2

          Someone should try it with graphene. 😉

          • Doug Cutler

            There you go. I’ve yet to identify the type of material used in the CONDUCTING plate of the EESU. I’ll ask EEStorFanFibb.

    • psi2u2

      Excellent summary. If anyone with that tech savvy is present, that would be great to know. How good are these numbers, really? Are they the full monty, or if not, how close are they?

  • SiriusMan

    I have seen it claimed elsewhere that the EEstor capacitor (based on barium titanate powder?) showed impressive performance when the device dimensions were very tiny but the performance dropped off sharply once they tried to scale the device up?

    Is there any truth to that? and does this new report address issues of scaling up to a size that is practical for industrial purposes?

    • EEStorFanFibb

      for more technical please see the report by Dennis Zogbi and the test report by Intertek.

    May spell the end to chemically based batteries
    How long will lithium ion battery industry last?

  • EEStorFanFibb

    yes accused of fraud many times by internet trolls of all kinds…. today he is completely vindicated by 3rd party proof his technology works and has value. Oh, if only Rossi could say the same.

  • LilyLover

    Oh my my! Finally the light at the end of the EEEStory!! I had given up the hopes about 2 years ago!! Thank you EEStorrFanFib!! Now the race begins … who could use them first? Rossi, Mills, Tesla Motors or the GM? Or Siemens? Let’s see. The Santa seems happy this year!

    • BroKeeper

      Yes, this is a timely capacitor storage breakthrough that could form a LENR symbiotic relationship in the near future.

        thanks, this article is well made, even if it is in the air today.

        if you are interested in accumulator, supercapacitors and others storage (flywheel, flow batteries…) I have a scoop.it

        http://www.scoop.it/t/accumulators-capacitors-and-energy-storage-systems

        it is not really “curated” more piled.
        if someone interested want to extract and curate news on accumulators&al my scoop.it is raw matarial for a better work.

        (I have same for turbine/TEG&al, and misc subjects like superconductors, business, epistemology, desalination, microgrid…)

        I am good in weak signal, but not is curating , feel free to exploit me.

        • BroKeeper

          Thanks Alain, great source collection of related technologies. I bookmarked yours as a prime reference.

        • pelgrim108

          I visited your LENR scoop-it often. Nice to know that you do other subjects as well. I have bookmarked them all as they are all interesting.

  • tlp

    this sounds sooooooooooo over the top…. oh to dream

  • psi2u2

    Good news for eestor. If we get LENR, eestor capacitors, and the Rohner Papp machine with decent cops, then it is all over for fossil fuels, except specialty uses.

  • Ged

    Very cool! Huge need to better capacitor tech, so let’s see if this takes off and how it’s used.
