Lithium-ion Batteries: 9 Years of Price Stagnation

From a pure technological standpoint, when you evaluate all the various gov. stimulus packages, loans and perks, one can clearly see the footprints of opponents to renewable energy at work. They are very clever in disguising this!
But the underlying strategy is as simple as it is effective: divide et impera....

Lithium-ion Batteries: 9 Years of Price Stagnation

Speaking of temperatures, (in)external heat is an inherent problem for for Li-ion packs. The cooling system alone adds ~$500 cost to a car. Then it drains about 100-200 kwh annual depending on what climate you live in.
If it fails on a hot parking lot: you come back to a car with a battery that is lost. An insurance company would cover the risk, but at a cost.......

Lithium-ion Batteries: 9 Years of Price Stagnation

The price stagnation is easy to understand. Before 2k real wages had increased and historically energy storage per dollar had been doubling every ten years -for the past 150 years or so.
But there is every reason to believe that there may not be any improvement in this for the next 20 years:
-U.S gov. debt causing inflation.
-globalisation and overpopulation -devaluing people.
-technological acceleration, keeping wages further down.

Therefore Americans -except for select elite- will simply not be able to afford Li-ion powered cars, even if mass production of lithiumcarbonate would be possible/desirable, which it is not:

-not environmentally sound. It would cause futher irreparible ecological damage to ecosystem.
-world demand from portable electr, light ev (bikes) will absorp much of planned production increases.
-realistic achievable production will be sufficient for only a small fraction of transportation needs.
-most lithiumcarbonate reserves in geographical areas hostile to U.S. politics, possibility of new conflicts of interest.

I think gov. loans to A123 etc. are very elitist. How does that help the American people?

Cleantech, Optimism Squared and the Battery Industry

Also, but that is just my opinion, one has to realise that investors (here and elsewhere) have poured many millions of dollars in cleantech, batteries etc., so we -investment community- kind of like to keep track of current technology and its limits, if you know what i mean.

Cleantech, Optimism Squared and the Battery Industry

Sorry, wrong. Can be found in the white papers here:
strategicpolymers.com

And BT is not a polymer.

And no not off-topic. Cleantech, batteries and (Optimism)^........

Above you gave link and said: (quote) "replaced with a material having dielectric constant about 6000"
Highest known polymer dielectric is a little over 50.
No 100 x energy density in that either...

Dave K.

No you have not answered any criticism regards 1-ltl.
No I do not accept that your tech is credible.
The opposite!! (now that its clear youre not following the route I outlined above)

Its not a matter of me not understanding self-healing. The problem is you not understanding dielectric saturation (strong electron-ion correlation as field stengthens, leading to cancellation between ionic- and electronic polarization in ceramic dielectric!)
K varies as ~1/E over much of voltage range resulting in approx. LINEAR increase in energy density with field.
You believe (common mistake!!!!!) using a 6000 K material will give you 100 x energy density.
You calculate total energy stored as 1/2 CV^2 without reporting any breakthrough on saturation issue. This invalid calculation 1/2 KE^2 then gives (.5)(8.85x10^-12 F/m)(6000)(10.6^8 V/m)= ~3x10^8 J/m3 = ~300 J/cc.
That's optimism squared!
In reality you're lucky to get 2J/cc with the link you gave...

Your website has been in the air a long time, yet:

-no patent (even though there are hundreds of US patents which make the same mistake out there -sometimes I wish the Swiss would examine all patents!)
-no energy storage measurements
-no permittivity versus field data

If you want to be succesfull in this field, the order to do things would be:
-to get a lot of Schaum's outlines, practice solving millions of problems incuding calculus.
-get mr Feynmans trilogy and complete at least part 1 and 2, be able to validate everything he says.
-then IF you get a good idea in the kitchen:
1.make it,
2. test it,
3. go to mr Peterson and get a patent,
4 get 3rd party verification of your measurements,
5 and THEN you can launch a website promising all the goodies to mankind.
And not the other way round...

Premarket rumor.......Solarworld to bid for General Motors!!!!!!

Cleantech, Optimism Squared and the Battery Industry

Ok Dave fair enough. I read you're aware of dielectric saturation in the case of Eestor.
I just wasted some 10 minutes looking at your renewed site.
To me meaningfull scientific statements -claims that you make- are a method of verification. Since no such method is in the air, your entire content (the rest) is meaningless to me.

That said, you claim 300J/cc. with ceramic/polymer material, about 10 x better than commercial and cheap ultra-cap in marketplace today.
This high energy density is possible -only in theory!- capped at about 400 J/cc as upper limit, in three phase composite with some nano scale fraction packed.
But achieving high breakdown strength is extremely difficult. For this you have to create a packing at nanoscale without defects, with some high order-a very difficult problem on which many labs are working today. And fusing doesnt help. In fact of the billion you manufacture one might come out right.
But if you have solved one of the toughest problems in nano kudos to you...

Good luck.

Welcome to the SA alt energy section.
Where we can open a box with 4000 years of math history and hundreds of years of physics to prove you wrong.

Cleantech, Optimism Squared and the Battery Industry

Oh no, here is an another one of those BaTio3 capacitor nuts.
Done any permittivity testing yet? I looked into patent. Fused but same problem as EEstor: high voltage, low energy density. Very low....

Cleantech, Optimism Squared and the Battery Industry

Please dont get me wrong, John.
I like your articles. But I am capitalist. I want to make money.
Show me how.

Cleantech, Optimism Squared and the Battery Industry

-Eestor is a scam (according to Cambridge University, electr. engineers etc.) Patent is flawed. They used a wrong formula. No prottoype. Mom and Pop operation in a shopping mall in Texas-

But John, the link you provided is RESEARCH. I dont see:
-price/mile.
-Range.
-Would I have to wait 8 hours at a charging station? (girlfriend wouldnt like)
-how would Big Government tax the juice in yur scenario?

Futher Blackrock, (BLK) evaluated. Contacted them. No dummies there.
Air France/KLM. No dummies there either.
