Sure, but it’s a pretty big if.

I have just come across this site and have found it informative and interesting with some great content.
“EEStor feels this is a huge milestone which opens the advancement of key products and services in the electrical energy storage markets of today. The automotive and renewable energy sectors are a few of the key markets that would benefit greatly with the technology.”
If this happens then it will be a good thing, would it not?

Firefly…a second life for lead batteries…without lithium…by Caterpillar?? On the market this summer.

“Firefly Energy Inc. (“Firefly”) is a Peoria, Illinois-based battery technology company developing a portfolio of lead-acid battery technologies and products to enhance performance within major portions of the $30 billion worldwide battery marketplace. The company’s first applied technology is a microcell foam-based battery technology, which can deliver a unique combination of high performance, low weight and low cost, all within a battery that unleashes the full power potential of lead acid chemistry while overcoming its performance drawbacks. Firefly’s battery products and their patented microcell technology deliver to battery markets a level of performance achieved with advanced battery chemistries (Nickel Metal Hydride and Lithium) but at one-fifth the cost.”

From Firefly’s web-site:

In the advanced battery architectures that Firefly has perfected, the MicrocellTM composite foam “grids” are impregnated with a slurry of lead oxides which are then formed up to the sponge lead and lead dioxide in the normal fashion. Because of the foam structure, the resultant negative and positive plates have enormous surface-area advantages over conventional lead acid grid structures. This results in much-improved active material utilization levels (i.e. from the historical 20-50% up into the range of 70-90%) as well as enhanced fast-recharge capability and greater high-rate / low-temperature discharge times.

The signal advantage of Firefly’s Microcell Technology™ is that it fundamentally changes the performance of active materials within the lead acid cell due to its unique architecture. Overall, the Firefly foam electrode structure results in a redistribution of most of the electrolyte (the biggest “resistor” in a lead acid battery) into the pores of the foam plate, in closer proximity to the lead chemistry. This is in contrast to a traditional lead acid battery, where most of the electrolyte is in the separator, more distant from the plate’s chemistry. Each foam wafer contains hundreds or thousands of spherical microcells (depending on the foam pore diameters). This leads to enhanced active-material utilization levels because each microcell has its full complement of sponge lead or lead dioxide and sulfuric acid electrolyte.

Well, how long does it take for zenn to do their proofing permittivity test? They have 5 days to caugh up the dough once they complete it. I would keep an eye on volumn of the stock in the absents of news. If the volumn goes up substantially, along with price, it is good news. If it goes up along with price decline, there is a dump happening – and znn will be a penny stock.

How long does it take to prove the pemittivity test?

Well, there are a lot of people who do not believe this tech. stuff. However when i seen the tests done at various tempatures (-30f to 240?), this is for real. 22% higher PR than was expected. Also clues that this tech. is new by what is described, not clearly, but discharge rate is not like a regular cap. Also the barium titanate is modified in the patent, so it does what it says it does at an increaced voltage. When Tesla started with his ideas, everyone was a skeptic. But with time history proved him right. If this proves out, like the goals have been met at each stage so far, then this will be the biggest break thru since the invention of the light bulb. I am excited. “Necessity is the mother of invention”.

Mr. Hamilton -

I don’t believe the 64% increase was due to insider trading. The increase was most likely due to a front page (on Yahoo anyway) news story that the US government was set to invest a bit of money into renewable energies and energy storage. This article mentioned ultracapacitors specifically. Since there are obviously traders that trade according to government spending they probably googled ultracapacitors and found out about Eestor and of course Maxwell and probably invested a bit in both.

I think Zenn’s press release about the trading activity shows that they were worried about how it was going to look to the general public when they issued the permittivity results. I’m rather skeptical of the claims but don’t believe insider trading occurred here.

Taking stock of Zenn’s ride

“Most puzzling was that Mr. Clifford didn’t want to discuss how close EEStor was getting to commercial viability, saying it’s not Zenn’s job to predict.

Really? But Zenn told investors it will introduce a car with EEStor technology by the end of this year. Surely management must have some inkling as to when these “batteries” will be ready. The company is standing by that prediction, incidentally, but it looks impossibly far-fetched given what we know from EEStor.”

About time a reporter sees through EESTOR’s and Zenn’s BS.

EEStor has updated the PR to include temperature range.

Smart Steve, there are scientist who will do and or say anything you want for a price.

Mr. Hamilton,
I apologize, I hit the enter button before editing previous post.

NO RESPECTED SCIENTIST AND OR TEST COMPANY WOULD PERFORM A CERTIFICATION OF A PRODUCT WITH THE TEST EQUIPMENT SUPPLIED BY THE COMPANY THAT IS PAYING HIM TO PERFORM THE CERTIFICATION.

If you get a chance, ask Dr. Golla when was the last time Dick Weir calibrated the test equipment he used to certify permittivity?
