Researchers at Stanford University's Department of Materials Science and Engineering have made a discovery that could lead to laptop batteries that last more than a day on a single charge.

The researchers have found a way to use silicon nanowires to give rechargeable lithium ion batteries--used in laptops, iPods, video cameras, and mobile phones--as much as 10 times more charge. This potentially could give a conventional battery-powered laptop 40 hours of battery life, rather than 4 hours.

love to see this trickle down to RC li-pos 1-2 hours off one batt. would be nice
were now your lucky to get 12-15 min
 
Haven't they made many solutions to eliminate the short battery life already? All these inventions and ideas are great, but it would make my day if they were to actually come out for once.
 
And lo god said, "let there be longer battery life", and couch potatoes saw that it was good.

And they wept.

And queued up another battlestar glactica on tivo.

And asked the wifey to bring them some chips.

And a beer since she was already bringing the chips.

And maybe one or two of those chicken fingers left over from last night.

While it sounds cool, I always take announcements like this with a huge grain of salt. How many times have we heard about great new technologies under development that for some reason or another never make it to market?

Dude, wtf. How many threads do you post that EXACT same comment in? You need to be poofed :p
 
...and components will suck up 10 times more power by the time these come out, given no nett gain :|

You have 33 posts over about 3.5 years. At least make each one different. Go into your clipboard and take out 'huge.' If you're going to clone your posts, at least get the idiom correct.

Wake me up when all of us can actually buy these super batteries.

And lol at above.
 
nice GJS, you know sometimes people can be robots

it would be nice to have a cell phone last more than a week without turning it off. but the bottom line for anything is that its all about the money. if new batteries like this would come out then the battery companies wouldnt be making as much money because you could buy one and be set for life. the real question here is isnt how long the battery last, its how long before it does not hold a charge.

omg nice find, lol, funny...

I would love if it made it's way to the market My laptop gets 1.3hrs on battery, even less when you try to game on it :(
 
I'd say this has a very good chance of seeing the light of day, firstly Stanford has an excellent record of tech transfer from academia to the commercial space, and second the silicon manufacturing process needed to enable this is very well understood (we wouldn't each be typing here if it wasn't), I'd say the question is more of a when, and if it will be a true 10x improvement per unit of battery.

The best (worst?) part of it, he stole that quote from someone else who posted it in a news comment here!
 
Like others have said, I'll believe it when I see it. There have been a ton of "We can make batteries better" announcements but, they are still the same batteries.

It's like all those huge MPG gain technologies that were reported about and never saw public sale.
 
What ever happened to Toshiba's Battery Tech they announced a couple of years ago that would charge a Li-Ion battery to 90% capacity in 60 seconds?

Nice! That was pure comedy right there :D
 
You know if these batteries ever make it to the "marital aides" products, alot of us men will not be getting any sex...

:p
 
We keep hearing about all these advancements in battery tech,but when are we going to see real and huge jumps in todays performance,and products ?

I am tired of hearing about these kinds of things,only to find out at the end of the article that its at best 10 or 20 years away.... :rolleyes:
 
My electronics all eat power like that Japanese guy does when having a hot-dog eating contest against a grizzly bear.

Maybe they could fit one of these into AA size so I could put them on a wii remote and only need to change/recharge them once every month or two. I'd like one before, say, retire?

That made me smile :D
 
I understand how this technology is supposed to work and why it probably WILL work.
This may be the holy grail that really makes battery powered cars viable and will be great for laptops.

That said, I also find it terrifying.

Basically, the energy density of a silicon anode Li-Ion battery is going to be 10x that of a conventional graphite based cell. Now, we have all seen what happens when a conventional Li-Ion cell fails catastrophically and releases all (or at least a large portion) of its energy at once -- i.e. fire + (firecracker to M80) sized bang.

Now multiply that by 10....KABOOM.

Basically, one of these suckers failing wouldn't just start a fire. It would blow up with enough force to destroy both the laptop AND the owner!
 
While the overall life might be down right now I do think the fact that almost everyone who makes batteries is beating down their door right now means that there is a good chance that even if it still remains down, it will not be by that much, maybe by the end of THIS year.

Hopefully, there will be a bit of sharing going on so that everyone can look at different methods of improving the life, and then collaborate on the best one (lord knows there is a LOT of $$ to be made by everyone)
 
For some reason, I have no idea why, this thread just reminded me that retailers sell "D" batteries at much higher prices than AA batteries, even though they have the same output. And now I'm angry. :eek: lol. Damn batteries!
 
You realize of course that with higher capacity and assuming it can discharge at a similar rate to a normal Li-poly, that these will just be able to create bigger and better fires in peoples pockets after they manage to short circuit them?
