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 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 contracts during use. That swelling and unswelling has generally led to complete destruction of the 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 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.

As a planet we need forests; maybe the planet now needs these nanowire forests to work for the planet...

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.

""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 this sooner rather than later.

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.).

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.

the less frequently i have to charge my gadgets ... the better ...
especially when i am running out of electrical outlets in my home ...
coz these days you need to charge everything ... from your car ... to your toothbrush ...
the less i have to charge ... the happier i am ...

That is more than made up for by the expense, complexity, and fragility of internal combustion engines. Imagine never having to 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.

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 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.
A battery with moving parts?

They've replaced the 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.

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

To beat the polution one has to create energy from non poluting sources (tides, wind ,waves ,sun ,hydroelectric) then store in the batteries

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 266 miles. (factor 1/75% = 133%)
But of course every increase is welcome :)

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

The big question here is, looking at the processes involved and the appropriate economies of scale, where is 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?
