Oh, what wondrous things come from the land of Korea -- dancing emotional robot humanoids, oxygen-emitting robot plants, and multiple 24-hour StarCraft channels. It's all good, and we dig robotics and televised gaming, but this latest invention could be our favorite if it pans out. Professor Cho Jae-Phil and his team at Hanyang University have replaced the graphite in lithium batteries with a certain kind of silicon, which we're told can store eight times the power. No word on what the batteries have actually been used for yet, but it stands to reason they could eventually make it to consumer electronics. Now you see why we're willing to say this might be better than 24-hour StarCraft. Say it with us: 48-hour StarCraft.
Now battery cars go further,
Or Nokia recalls more battery in future,
You make it sound like the lithium battery are made by the infested terran.
Now battery cars go further,
Or Nokia recalls more battery in the future.
Eight times the exploding power!
Somehow your comment is over 9000 times better because it appears to be coming out of the mouth of a cartoon velociraptor.
That is SO a Tyrannosaurus Rex.
What ever that is clearly a small armed Iguana.
Also...
8 x 24 != 48
Is this
No offense, I find people that use their real pictures as their avatar somewhat douchey. It's nothing against you, and I don't like calling things douchey (because doing so is in itself, douchey), but something tells me that you're overconfident about how you look. Don't assume that I have a low self esteem, and that I must censure people who have a greater ones. I just think a pokemon or album art is more pleasing to see than a picture of someone who feels too confidently about their face. Why not show your hands, or your feet? What about your face sets you apart from everyone else?
yyan, that was classic!
I don't know. I think it's alright to use your real face. It's a more personal approach to comments. I'd rather see someone's face than most other things. It lends their comment a more "HUMAN" feel.
I just don't care for seeing random peoples' faces. All they are is another face, while an avatar at least says something about them.
AVG, I think that it's good to cut the personal cord from these comments.
What do you think. Are we human? .. Or are we denser?
Methinks yyan is one of those big fat people.
I'm on the side that using a real pic is OK and not dooshy. I don't use a real pic but I got nothing against it. Why would I? I think someone here has a bad case of the "Mondays"...
BTW I can't even change my pic for some reason. So is no pic better than any pic or the other way around?
i use my real name , and somtimes my real image, so what .... it's more human and real. instead of that stupid Pokemon picture!
You said it was his face?
yyan, I really think that it is totally okay to use your own picture, I'm confident about myself and I do really love have a more human approach through technology, isn't that the way it should.
I think yyan that you are slowly losing confidence of yourself, or to put it in a better way, you believe that it is okay to be distant from other people through using fake imagery like if we were living in a video game or a virtual world. Don't get me wrong, we are actually talking in a virtual world, but one of the big missions that we all have to work on is the fact that we should make technology more human, it must build up our self confidence and the way we live, it also creates some type of a responsibility in everyone's mind, whenever I post something I make sure soul and heart that it will not represent me in a bad way because it is really "me" who is talking. We will say stupid stuff, but when we talk as ourselves we will always try to be as respectful as possible.
I would love to see everyone in here using their own pictures while commenting, it will be like a real & "more human" community rather than just a bunch of pokemons having fun and leaving the place without any connection to the blog, and said before, put your picture for a while then have a different picture some other times, at least believe in yourself and trust your judgments in order for us to respect your opinion even more.
Thank you for bringing this up though.
Your second reply was way more human, and made more sense than "Is This." I mean where's the human side to that?
but this is my real picture.
yyan, is that because your picture would be of an ass?
I think the face is the thing that, as visual indicators go, says the most about a person. Of course, not so much in a photo, especially a driver's-license type style one where everybody tries to appear as attractive as they can (while looking relaxed and approachable, of course). But ever then, you can see something in a person's choices, and a little in their background, age, etc.
I think it's as worthy a representation as my pikachu in a mario hat. And not in the least obnoxious. He's just smiling in an undoctored photo.
I think I should probably show my face too after saying that.

But I don't get what the original post's about. Best I can surmise is it's a rather out-there joke about a laptop battery dying.
Nah, I'm not really into Pokémon.
so what's that say about my avatar?
giggity giggity goo!
But they have to make the batteries last roughly 3 hours. This is so after a few years they deteriorate to unacceptable levels. Otherwise the bottom end of the market will fall out from all the grandparents and luddites who thinks it's just broken and buy a new one.
the double comment post?
your face again...
You better hope that movie is, "Spammy McSpamerson: Corporate Tool".
Does this mean eight times the blast radius of an exploding battery?
Good heavens no. Eight times the blast _volume_.
..I don't feel like running the numbers for the radius now.
Yeah man,
It's more BANG for your buck. :P
Are you serious? You don't feel like "running the numbers?" The cube root of 8 is 2. So the radius is doubled. Of course, that assumes there's a linear relationship between battery power and explosion volume - and I would love to read an academic paper on that topic.
jaydizzle:
Your calculation assumes a cubic explosion... The term blast "radius" implies a spherical area. I think you're the one who shouldn't be running numbers.
JL if you paid even the slightest attention in math class, you'd know that the volume of a sphere is also proportional to the cube of the radius.
jaydizzle is right. its really not that hard.
I disagree- it's a very difficult calculation, but i think Donkey Kong is the best game ever.
A Samsung or LG battery photo would be more relevant
But do they have a channel with 48 hour Crysis?
Nope, but maybe one of the two Starcraft channels (that's just on analogue cable) will switch one day to Crysis.
Hanyang university is one stop away from me. Maybe I'll go down there and swipe a new bat pack for my lappy...
control Blizzard and you will have control of the Korean people...
though this stereotype is slowly diminishing...just look at Grubby and players from the PRC.
if you are hoping for change, you'll be happy to know that one day, those starcraft channels will become starcraft 2 channels.
Why is it that for every story on engadget someone has to mention crysis. Geek!!!
Excellent post. For the record, great women also come from the Land of the Morning Calm!
True true. And I'm proud to be Korean considering this is coming from there. But it would suck if 8x's more battery recalls occurred!
Oh, and to everyone up there talking about personal pics and avatars, who cares? This is my pic, but you can't see my face... that was why I took it back when my hair is long. I do think some avatars are hella funny though of course.
Have heard this before and once again, it sounds great.
However, for the love of all that good in the universe, show me the distributor where I can spend my money and buy one right now ...
No more foreplay.
90% more energy but last 8 times longer...am I reading this right or should it last 1.9 times longer.
This is a classic Korean breakthrough. The blog cites no source for the information, and the numbers make no sense. The Gadgeteers exercised typical editorial judgement with this obvious bullshit.
From the article: "Cho and his team have developed lithium batteries that are 90% more energy efficient then current batteries. That means you can do whatever it is you do eight times longer!"
I really don't get that...
Wow Korea is full of geniuses indeed, no wonder Japanese want to conquer their land hundred years ago.
The japanese are like the Romulans and the Koreans are like the Klingons. The Klingons are always pissed off and hostile but at least they are straightforward and predictable. In that way, easy to deal with. The Japanese will smile and bow and suddenly your fleet is at the bottom of the bay in Hawaii on a sunday morning.
Ho hum. This is a silicon-based anode, which has higher capacity than carbon but has to expand almost 3x to provide that kind of capacity. And, it's just the anode, which takes up usually less than 50% of the total battery volume, so total cell capacity will be much lower than 8x. Everybody and his brother is working on silicon anodes. See the "groundbreaking" press release from Stanford a while back as an example. Also, they have not identified a suitable cathode to complement it, so they can certainly not claim to have a whole battery that is capable of 8x more energy. Every time one of these announcements comes out about a higher capacity anode or cathode, it gets misinterpreted by every blogger as the next great thing in batteries. There will not be a lithium-ion battery with 8x capacity increase, it simply can't be done. Optimistically, we could hope for 2x improvement some years out, but don't hold your breath. If you want something interesting, start looking at metal-air couples, that's where you can start to approach 10x improvements over existing Li-ion.
Word, son.
Damn.
Not only did he bring it, he brought, laid it on the table and rubbed your face in it.
Engadget just got served!
Thank you, I used to build lithium power cells for JPL, your remarks are accurate.
So, when you say Korea...you're talking about the part the US invaded, right? Cuz a US invasion is always a bad thing. I'm sure I read that somewhere. I want to apologize to all those people for not respecting the sovereignty of their country, so they can be all un-occupied and un-invaded. Like North Korea.
Liberation of a country produces superior technological competition. Let that be a lesson to us! Soon, Iraq will be able to produce things like this, and then where will we be? Even further behind!
we've got macdonalds, and the iphone
As long as they don't charge the x8 price of the regular batteries everything should be fine.
Old news?
http://www.engadget.com/2007/12/19/stanfords-nanowire-battery-leapfrogs-li-ion/
There has been lots of talking about this, but launch a working product and I'll believe it.
Are you sure that this can be used in laptops? A lithium battery and a lithium-ion battery aren't the same thing, from what I gather these batteries will not be rechargeable, and therefore will not be used in laptops, more likely they'll be used in toys etc.
It's OVER .... over 8000 ... : (
interpret as you'd like
if it were 8x the power it woudl be of course.. 800 ..% nice try folks!
I totatly agree, that's why i use my pic for my avatar as well.
Hmm, me thinks i should have hit the reply button on a certian post. Soooo in reference see earlier comment about Dooshy McDoosherson...
The Wireless subscriber you are trying to reach is currently not thinking properly.

You guy have inspired me to upload my picture as well.
2 words... light sabre. Woohoo!!!

A silicon anode, by comparison, can hold a much greater charge—4.4 lithium ions per single silicon atom. But because silicon swells to four times its volume when charged, using it in a battery causes the anode to break apart, rendering standard silicon useless for power. The breakthrough is in the discovery that, while 100-nanometer-wide silicon nanowires expand, they do not break.
in the source article it clearealy states that they improved the life of the battery with 90%. This is not even close to 8x , in fact it is short of 2x. But anyway, if it's true this is amazing.
Seven..minute...abs.
Fake. Especially given the fact that the new battery technology 'invented' by Koreans.
"Cho says commercial production of the new, high-capacity batteries could begin as soon as four years."

4 years?
Uh...current enthusiasm quashed.
