A new stretchable Serpentine Lithium-ion battery has been unveiled this week, which is still capable of providing power even when it is stretched to three times its original size.
The stretchable Serpentine Lithium-ion Battery has been developed by a research team partnership between Northwestern University and the University of Illinois.
The ability of the stretchable Serpentine Lithium-ion battery to be pulled is down to the inclusion of electrode interconnects constructed from serpentine metal wires.
The prototype stretchable Serpentine Lithium-ion battery is capable of expanding to three times its original size and the serpentine electrode interconnects unfurl in an ordered way to keep the connections within the battery alive. The development team explains:
“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 lines,” said Huang, a corresponding author of the paper. “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.”
No information has been released as to when the prototype stretchable Serpentine Lithium-ion battery will be arriving in commercial products, but we will keep you posted as always when new information is released.
