Korean scientists solve flexible battery riddle

We've got flexible displays, printed circuits, memory and even chargers -- why not batteries? So far, this has eluded manufacturers, but now researchers from the Korean Advanced Institute of Science and Technology have got the ball rolling with a high performance bendable lithium-ion version. As the video after the break (no sound) shows, the peel-and-stick type manufacturing process they devised allows the cell to provide constant juice, no matter how much it's deformed. Now the scientists are looking at ways of upping the capacity, so they can power more than just Christmas tree lights and ultimately bring "the next-generation of fully flexible" devices to market. That's no small thing, considering what some products are willing to do to fit into those tight aluminum jeans.
