Flexible battery coming for smartphones?
We all have been looking forward to seeing what kind of handset design might come out of Samsung's work on developing a flexible AMOLED screen. There were reports last month that Samsung is ready to produce these bendable displays starting this quarter. The only drawback to a display that moves like Gumby is finding a battery that is just as easy to flex. It looks as though the search might be over thanks to the Korean Advanced Institute of Science and Technology.

Under Professor Keon Jae Lee, the Institute has developed a battery than can bend, twist and fold without losing power or performance. You can click on the video below to see the direction that smartphone batteries might be taking. and while you might think that these flexible parts are being developed to make devices that more easily fold up in your pocket, the main concept is to develop parts less likely to break under certain circumstances.

The flexible batteries are lithium-ion, rechargeable and are printed on thin film. There is no precise word on how far away we are from seeing this employed in a consumer gadget, although Professor Lee says that we will see it used in "next-generation fully flexible electronic systems."

It may be a year or two away but between screen,this battery and hardware being foldable like a wallet we certainly are on the verge of seeing another big leap in innovation in most probable future Galaxy handsets.

but we can start with much more resistant phones

Flexible phones would be much more resistant,the lotus glass said to be used on such handsets is flexible and almost completely shatter proof.

Having the ability to change shape will massively help on drops and impacts as the biggest cause of phone damage and screens shattering is a solid rigid stucture object falling and hitting off another one ie. concrete etc.

The iphone is a prime example of this,rigid and solid glass and metal coliding with tiles or concrete ends up in disaster most of the time!

That is the same reason there are curtains between sections on planes. During turbulence, planes bend. This disturbs passengers when they see it, hence, the curtains. If the planes did not bend, then they would break catastrophically.

the Gorilla Glass craze ended as soon as it started, especially when people discovered that glass is still glass. Stronger doesn't always mean less breakable. Glass is glass.

Flexible displays are cool, but what about flexible CPU, RAM, and Motherboard? The entire phone won't be flexible, but a flex screen and battery is a good start.

My only concern is with just how flexible these Li-Ion batteries will be without somehow shorting out and producing a Chernobyl event.

I don't think Ive talked about flexible phones, I think is more useful to think in terms of flexible screens that can absorb impact and get less damage. flexible battery and screen can help with that

Apple will never get flexible screen from Samsung.

Unless Apple will steal idea and patent it.

Too bad Apple doesn't make hardware :)

But still can steal idea and patent it. :D

I'd be interested in knowing the amount of mAh it can hold. Not too many I guess. But a good idea would be to make a dense pile of such bendable batteries in parallel connection.

Let's worry about making them more energy dense first, then worry about bendable.

Agree, capacity is important, but size and flexibility also it depends where you use battery. There is situations when priority is size and flexibility and only in second place capacity. I tink that all features must be improved.

flexible smartphone here we come,we still have to wait for many years before someone makes it.

Until Nvida or Samsung develop integrated flexible 2 Ghz processors and memory chips phones utilizing this tech will be a years away but the good thing is that the individual components are making their way here.

flexible screens and batteries are a major step in a new direction but there are still many many components inside that are not. Thus, this is probably years from being of actual real use but its potential at least allows some wrap around screens and interesting form factors.
