Amazing recharge and storage properties. I was reading somewhere else that the system is over 300% better than lithium-ion in storage and cycles far longer.

I think you mixed your sources up -- the article linked talks about using nano tube soaked paper instead of metal as electrodes in capacitors and Li-Io batteries. Sounds like you are talking about a new battery technology ?

He is Grendel. This is too cool for words. (rats Can, ya beat me to it! ;))

Video HERE

Read HERE at the Stanford site where it was discovered.

More Technical specs HERE . Looks pretty impressive.

Also new plastic based nano carbon films placed over OLEDs increases lumen output 3 fold in some apps, increases life, and allows them to become flexible panels. We are going to have some pretty cool gadgets hit the shelves in a few a years.

Wow this is ridiculously old news to me.
I read an article in one of my JW magazines about this very thing a long time ago. Hmm, wonder if they are finally going to stop being greedy and mass produce these things.

you don't blindly throw new tech out into the market. It needs to be tested and find what it's limits are and precisely what happens in which apps. Also, this was with just regular paper. What if the paper is spiked a bit? it all needs to be worked out.

S13driftAZ please explain how you read about this \"old news\" when it was announced last Wednesday? The nano ink used hasn't been around very long... maybe something similar with different materials?

Well that's cool.

When can I get lithium stationary?

Heh, slow news time or Stanford is desperate.

If you check the links (non-video) that I posted; the Standford site was posted on the 7th. The last link (which was a link inside the Standford article) was posted ...hm.. /me digs through page source code... looks like Dec 4th. But the article was submitted for review in August.

THIS may be the source document for Krom's first link.

Interesting as there were supposed to be patents filed. ... how is it that Standford is raising the banner on this?

Well, from the names the Stanford team is mainly chinese..








:lol:

Interestingly the Rensselaer team seems to be mainly indian..

I couldn't tell you what article it was off the top of my head, but I might be able to find it.

Duper has the correct link... the 2007 technology does not use silver wires, the 2009 does. The 2007 technology cannot be printed yet, 2009 tech is readily printable with current technology. Also 40,000 + charge discharge cycles on the alpha model is impressive. The older article is a more proof of concept article. You can be like , \"bah, that's old\" I myself am impressed and excited.

No, no, don't get me wrong, I think its very cool.

I was just surprised by the fact that 5-10 years after I read that article, the technology is starting to surface.

I've seen so many "new breakthrough technology blah blah blah will be available in the market in 1-2 years" over the last 10 years, and have yet to see anything actually available as a product.

Well OK, OLEDs are finally starting to show up as actual products in some places but that is different, they have been talking about OLEDs since before I was born. :P
