Researchers Extend Lithium Ion Battery Life 10X

Yes...I mean that if your laptop currently gets 2 hours of unplugged life, these would get 20 hours. Holy Schmoley!

The new batteries use silicon nano wires to basically reinvent the way that the http://eatingdisorderrecovery.com/canada-generic-levitra batteries electrodes work. Instead of using carbon to store the lithium ions in the anode, they're using silicon. Silicon can hold far more ions; however, it actually stores so many ions that it literally swells during charging and generic cialis online contracts during use. That swelling and unswelling has generally led to complete destruction of the the best site buy levitra in new zealand anode over very little use.

The silicon nanowires allow the anode to absorb the lithium without breaking down. The nanowire "forest" (yes, they actually call it a forest) expands to four times its original size during charging, but the wires don't ever fracture.

The batteries could be used to store electricity during off-peak hours or to buy levitra in england power portable electronics. But the real exciting possibility is that these batteries could power electric vehicles that would store more energy than could be stored in a tank of gas!

Of course, one never knows what will happen when you move a technology from the lab into manufacturing, but this technology is revolutionary and extremely promising.

Does this mean that a battery the size of the Tesla Roadster's could achieve a range of cialis label more than 2000 miles on a charge??

The big question here is, looking at the processes involved and the appropriate economies of scale, where is on line viagra purchase the price point per unit volume, weight, and especially kWh? Is this something that would be a great technology but prohibitively expensive for use in an electric car?

If this transitions from lab to laptop - lab to road - relatively inexpensively and safely... we're looking at the technology that will power the next decade or two.
As a planet we need forests; maybe the planet now needs these nanowire forests to work for the planet...

Based on the viagra from india length of time to commercialize new battery technology, scale up manufacturing, optimize and tramadol 180 cod feww ahipping cost reduce, and then design into a production car... it's probably a minimum of 12-15 years before this could be seen in a showroom car. So, weee, it may be the power source for the 2020's, if we're lucky, but doubtfully before then.

Whoa! Simmer down Juniad. :)
Batteries are still expensive, you wouldn't get a 2000 mile range unless you really paid for it. Realistically, manufacturers would use smaller batteries, helping bring down the cost of battery powered cars. Also, it'll be many years from now when this technology gets into cars (if it ever does).

The sooner the better though.

What about solid-state HD laptops?
written by Aunty Proton, December 18, 2007
If it can extend battery life 10X for a laptop with a regular HD, how much more would it do so for one with a flash memory HD? 40, 60, 80 hrs. on a charge?

About how long it might take to viagra buy now get this in the market place, from the article:

""Given the mature infrastructure behind silicon, this new technology can be pushed to real life quickly," Cui said."

and

"Cui said that a patent application has been filed. He is considering formation of a company or an agreement with a battery manufacturer. Manufacturing the nanowire batteries would require "one or two different steps, but the process can certainly be scaled up," he added. "It's a well understood process.""

So we'll probably be seeing more of buy cialis online without a prescription this sooner rather than later.

Unfortunately...
written by Anonymous, December 19, 2007
There is a >99% chance that this technology will never mature, simply because that's the mortality rate for technologies which do not already have a working process for mass-production. I would love to have this kind of technology, but I'm certainly not going to expect to even hear anything about it again let alone see it available to consumers.

Silicon...
written by Trophaeum, December 19, 2007
And here in lies the problem, silicon is expensive, the question i guess really is how does it compare to the cialis tablets vs viagra previous technology in costs? Then again, increasing capacity 10 fold also means that you could supply a lot smaller battery that is lighter and still have better capacity so that may well outweigh the costs... will be interesting to see what happens!

Silicon is cheap, nanowires are expensiv
written by Alex, December 19, 2007
Silicon is the largest element in the earth's crust (very cheap). Making it into crystal wafers for semiconductor material is expensive. Making it into nanowires is cialis from mexico probably also expensive if not impossible in a large scale manufacturing environment.

There are many technologies that boost performance/efficiency that do not translate from the lab to the world (ex. carbon nanotubes, nanotechnological supercapacitors - which could be used in future cars, etc.).

Nice idea, but ...
written by Battman, December 19, 2007
the anode accounts for about 25% of a battery's volume. You need a cathode, a separator and current collectors to complete the battery. While Si may have 10x the ion absorption of Carbon, if you turn it into a forest which is 90% air space, you are back where you started. If only we could run our electric cars on hype! :'(

Power source?
written by John, December 19, 2007
Even if this technology works, and can be produced, it is really just the container; the equivalent to the gas tank. We still need to come up with the technology and infrastructure to produce all of the energy need if we want to run cars this way. And, unless there is a corresponding improved charging technology, it still isn't convenient: who is going to wait hours to legal pharmacy online charge their battery? Oh, and gas tanks are cheap, reliable and durable; these batteries will need similar characteristics for automotive applications.

written by OhBoy, December 19, 2007
That has over 60% of the World Reserves and its turning socialist... Bolivia. 10% is in Northern Argentina being harvested by an international company (depredation comes to mind) that depleted Chile's reserve (5% of the Worlds reserve). Next stop for Lithium the the best choice levitra no rx asteroid belt.

Now, you couple that with the fact that this international conglomerate was not allowed into Bolivia when it was a capitalist state, can you imagine what it may be like in the future?? Nice Idea, but the raw material may be inaccessible.


Specially now that Bolivia may become two or more different little states.

That is more than made up for by the expense, complexity, and fragility of internal combustion engines. Imagine never having to i use it generic cialis soft tabs take your car for an oil change. Ever. Direct drive electrics have no transmission to go either. And remember, internal combustion engines in cars have had a hundred years to mature. Electric cars are just getting started in a big way. It's a bright future.

This is a great demostration. If it works, the possibility is endless.
There is still see a physical/design challenge for a new battery using Si-Nano-Wire. with Si nano-wire, it still swelling. 4 time of viagra online without prescription its size. Inside a portable battery, the space is confined and filled with hard(liquid) materials. The challenge is to design this battery structure to accomodate the volume change during charge cycle.

Anodes? Why replace the part that works
written by Joel, December 20, 2007
The anodes in Li-ion batteries are what works best.

They've replaced the viagra price in canada electrolyte with a polymer, which is really great, but most of the improvement to be had in such batteries is in the cathode materials.

What will keep such batteries expensive is not the Si nanowires, it's the cost of the cobalt to match that capacity on the other battery terminal.

By the way, the cobalt for cathode materials is also much heavier, more toxic, and comes from less politically stable regions than the cheaper, longer-lived anode materials.

Lots of good advancements have been made on that front, however. Otherwise the Chevy Volt would still be a concept car.

Despite the many naysayers, this is certainly a step in the direction of sustainable travel, after all what is the alternative.

As Aunty Proton mentioned above, the coupling of this new technology with other new technologies such as solid state storage and OLED screens could see the battery life of laptops increase by over 100 fold.

In terms of levitra daily travel the 2009 Prius will likely come out with a plug in version so the viagra delivered overnight increased battery life that these batteries could provide would mean that for most trips no petrol would have to be used.

Electric utility companies have no way to store the energy they produce. Therefore, during the off hours from midnight to 6 AM they run the current into the revistaneon.net ground. I expect you will be able to charge your car during these hours at very little cost.

10 times is only 1.33 times or less
written by Marco Caflisch, August 13, 2008
As said before (by Battman , December 19, 2007)
these Nanotubes decrease the weight and size of the anode only.
With the the anode making up 25% of the volume, and the anode shrinking 10fold, the final battery will still be 77.5% ((100%-25%) (25%/10)) of the original Volume, unless we find other technologies which can shrink the rest. But that's not that easy...

So instead of increasing for example the Tesla driving range from 200 to to 2000 miles, it will only go to buy cialis online pharmacy 266 miles. (factor 1/75% = 133%)

But of course every increase is welcome :)

Okay although better batteries would ofcourse be nice.

WHERE DO YOU THIS THE POWER TO CHARGE THE BATTERYS COMES FROM!!!


Do you not realise how inefficent the electricity grid is, like 20% efficent.

Quoted in a new article recently, a 5% increase in grid efficency would = 53Mil cars being driven
