That's a good point.  Fabric memory (or retention) is important.

I doubt that this would be placed on the body at a joint (elbow, knee, hip, etc).  Proper placement, at the forearm or shin for example, would help increase the lifecycle.  3x stretch isn't very much for a textile.  From what I can see, the construction has a "bounce" to it that allows the give in the fabric without compromising the metal.

I agree, William K. Stretch and release of the material would be key. Maybe it's a little too early to ask this question, but I do wonder what the elastic properties of this material are like. Also, if it's bent at a right angle, would it be subject to strain hardening? Those may sound like little details, but they would bear on the battery's ability to be useful throughout the life of a product.

STRETCHABLE LI- ION BATTERY

  Good post Cabe.  I can certainly see how this could improve the lives of many individuals.  From looking at your illustration, it would appear the weight is minimal with materials that are seemingly "off the shelf".   Do you have any information on how this is funded; i.e. private, Federal, etc.?   The reason for asking, I see many federally funded programs being cut over the next few years and this appears to me to be a very worthwhile investigation.  It would be a pity if it got cut.

Bob,

The project was funded by the "Initiative for Sustainability and Energy at Northwestern University." In house, quite possibly the best way to get financing.

Flexible devices are the next step. I see it mostly used in keeping the device safe from damage. But unique designed gadget are sure to immerge.

Samsung makes bendable displays... Apple makes a bendable watch.

Cabe - I didn't know that Samsung (or anybody for that matter) had a bendable display like that until I saw your post and googled it.  The general nature of flexible design has a lot of cool possibilities going forward.

Cabe , i didnt knew that samsung is using stretchable lithium ion batteries and producing flexible screens before your post .No doubt these batteries are the very next technology although a lot of work has to be done in it.These stretchable batteries can also be used to power the bionic eyes

Apple makes a bendable watch? Interesting. Is a bendable iPhone on the way? Now that would be cool...though a bit delicate, I imagine!

Elizabeth,

Quite the opposite of delicate, the bendable tech could take more of a beating. Durability will be the most coveted feature. In the future, we will not need phone cases and screen protectors.

Combine this with insulating the circuitry from water, a recent trend, and we will all be happy.

Debera & Jack,

I saw the Samsung demo at CES 2013 back in January. With tech ideas like this, it always takes a while for the generational increments to catch up to concepts. Think concept cars versus the ones actually produced.

As Apple stops buying chips and things from Samsung, Samsung will need a new cash cow. Since I am sure they are patenting their bendable tech, keeping it out of Apple's hands, they will have to push the flexibility angle.

I look forward to more rugged tech as a result.
