Foldable, Stretchable Lithium-ion Battery
John A. Rogers, a researcher at the University of Illinois came up with the flexible lithium ion battery. The new, stretchable batteries will have potential in fields where normal, rigid batteries may not. It has a similar voltage as a normal battery and can last without a recharge for about nine hours.
Yonggang Huang and John A. Rogers collaborated in the research paper for this battery and said:
We start with a lot of battery components side by side in a very small space, and we connect them with tightly packed, long wavy line. These wires provide the flexibility. When we stretch the battery, the wavy interconnecting lines unfurl, much like yarn unspooling. And we can stretch the device a great deal and still have a working battery.
