Re: Energy storage

[Jazzjerry]

About storing Energy better,

Search EEStor in Google....... lot of rumors going around. This could be the breakthrough that makes even the best Li-ion battery's obsolete. In a sence by just improving the design of a cappacitor.



Here is an article about it (its in Dutch though)

Thanks for the quick response finding some english translations Hardcore.

Those are some big claims for EEStor, a very secretive company in Cedar Park, Texas. They claim to be working on an electrical storage device that they’re reluctant to call a battery, for the simple reason that it does not use a chemical reaction to store the energy. Instead, it is rumored the device is made of a ceramic powder coated with aluminum oxide and glass, and would indeed take five minutes to charge, as opposed to hours, as it is now with batteries. Such behavior is sometimes described as being an Ultracapacitor. A car powered by such an engine would have a range of 500 miles, on a 5-minute charge that would usually amount to $9 of electricity. $9 for 500 miles works out to about 45 cents a gallon.

Unlike its battery counterparts, this device could charge and discharge hundreds of thousands of times. Also unlike regular electric cars, it would be able to power a car in such a way as to make a four passenger sedan drive like a Ferrari. An engine made from EEStor’s “batteries” would cost approximately $5,200 which is a premium over conventional engines, but the company expects people will realize that the premium can be quickly offset from the expected savings.

There is no word on when exactly this technology will be commercialized, though 2008 seems to be a target.

We must have missed it!

There is one problem, EEstor haven't delivered a working prototype for public view.

Their ultracap is believed to hold 52kw of power.  And cap is believed to hold 3500 volts of energy, predicted to peak higher.  Using ultra high voltage cells, or capacitors to store electricity, is one way go as the energy is packed super tight and energy dense.  The science of energy storage theory, is using a particular reaction of electricity (capacitance) and relying on a given material highest permittivity to protect leakage, and assures ionic breakdown of that material doesn't occur.

The concept lends it self working ways around the limitations of low cell voltages in an aggressive manner. 

Saturation is what the sceptics are saying this will be this inventions fail point.

Maybe they have found a way to suppress the charged field high voltages are plagued with. 

Who knows what's going to go down.  People are reporting on what goes on out the back of, and what goes of the eestor companies doors  and stuff.  They seem to have a following of believers.

They still claim something is going to happen soon.

A newly released patent.  This one is quite detailed.

This would be very nice........

7.2 Increasing Energy Efficiency Technologies
7.2.1 New Capacitor Promises 10× Improvement over Batteries in Charge/Weight Ratio Lockheed Martin has signed an agreement with EEStor of Cedar Park, Texas for the military applications of a new type of ultracapacitor based on barium titanate that Lockheed Martin believes will be able to hold 10 times the energy or 1/10th the weight of typical batteries.

WORLDWIDE EMERGING ENVIRONMENTAL ISSUES AFFECTING THE U.S. MILITARY Control No. (TCN) 08152 with Battelle Chapel Hill Operations for the U.S. Army Environmental Policy Institute

“4.3.3 New Materials Provide Hope for Improved Ultra-capacitor EEStor, of Cedar Park TX, claims that its electrical energy storage unit will have more than three times the energy density of the top lithium-ion batteries today. The unit is based on a ceramic material consisting of a barium titanate powder coated with aluminum oxide and a type of glass material. Some experts have expressed doubts about the material’s ability to withstand the high voltage gradients necessary to achieve the stated capacities, but others are more supportive.

Military Implications:
The military should follow this development as it progresses toward production status, and evaluate components based on it for applicability to energy storage for environmentally friendly and improved performance systems and vehicles.”

The military cares about the environment? Maybe, until war breaks out and then they blast it to pieces.

They prabably use the environmet stated here as a place where they have no acces to powergrids and harsch war conditions instead of the greeny thought that pops up in most of oer minds when talking about the environment.

Don't be fooled, the pentagon is by far the biggest polluter on this planet.

Pentagon's Role in Global Catastrophe: Add Climate Havoc to War Crimes

In evaluating the U.N. Climate Change Conference in Copenhagen -- with more than 15,000 participants from 192 countries, including more than 100 heads of state, as well as 100,000 demonstrators in the streets -- it is important to ask: How is it possible that the worst polluter of carbon dioxide and other toxic emissions on the planet is not a focus of any conference discussion or proposed restrictions?

By every measure, the Pentagon is the largest institutional user of petroleum products and energy in general. Yet the Pentagon has a blanket exemption in all international climate agreements.

Maybe the issue with this technology being released or even demo'ed is the Patent - note the filing date is 15/6/2006 and the "Publication Date" is the 19/01/2010 - not knowing much about Patents I am guessing the Publication Date is the date of Patent being granted..

It would make sense that they have not released any meaningful info, data or demos as they where not protected via patent..

I personally HOPE they can do what they say they can and we see small, high capacity, fast charge power sources available very soon - that makes this whole ebike thing pretty exciting !!

Not to mention Depleted Uranium

Indeed, but I think we're getting to far off-topic now (and I doubt anyone here would like to be confronted with the large amount of horrible birth defects it causes, for example).
