Researchers show flexible, stretchable lithium-ion battery

Researchers have announced the development of a lithium-ion elastic could have many applications in the industry, especially with the growing interest in soft computing across consumer segments and other technology.

Using a process called “unravel ordered:” John A. Rogers of the University of Illinois and Yonggang Huang of Northwestern University say their battery can be stretched up to 300% of its original size without losing functionality.

Without taking anything away from the device, its design seems quite simple: the energy storage islands and “serpentine” cable connections are placed on a sheet of polymer. Naturally, the polymer is flexible and elastic, while the wave superposition cabling can go on the trip without damage.
Power-wise, the engineers say their solution works similarly to a standard lithium-ion battery of the same size. It lasts eight to nine hours and can be recharged wirelessly, although the current prototype loses some of its capacity after about 20 reloads, so more research is needed before it goes commercial.

“A major trend in electronics is the development of materials, mechanical design and manufacturing strategies that allow the use of unconventional substrates such as polymer films, metal foils, sheets or rubber sheets,” wrote the paper provides researchers through nature Communications for $ 32.

“The last possibility is particularly difficult because the systems should adapt not only bending but also stretching. Though there are several approaches for electronics, a persistent difficulty is in power supplies that have similar mechanical properties to allow his co-integration with electronics. ”
