The United States developed a scalable battery based on paper-cut skills
The 11th issue of ScienceReports published an online paper on materials science that describes a retractable battery based on paper-cut skills. It can be extended to more than 150% of its original size while remaining functional. The new battery can be used to power smart watches, can be easily incorporated into the watch's elastic wristband, the future in the development of similar devices or will replace rigid batteries and bulk batteries.
Elastic scalable energy storage device for a variety of "impossible task", some of the traditional battery can not be involved in the device, will be able to be driven by this new battery. Historically, researchers have taken a number of approaches in developing such new batteries, including the idea of ​​folding to produce foldable batteries using the concept of origami. However, the origami-based device can only be folded in one plane and the resulting surface is very uneven.
Now, these problems were solved by Jiang Hanqing and his research team at the University of Arizona. Their design for lithium-ion batteries uses paper-cut art - a form of origami that now combines the folding and trimming techniques to create a completely new battery that extends its functionality to the original length More than 150%. As a test, researchers stitched the cell prototype into the smart watch's elastics, which still power the watch when the battery is stretched.
This flexible battery will facilitate the design and manufacture of stretchable electronics. The authors propose that new batteries demonstrate the potential of portable wearable devices that can replace rigid batteries and bulk batteries in the development of compact wearable devices.

The biggest advantage of this battery is that it can solve the traditional battery placement difficult to meet. The flexibility of the battery, directly determines the design and manufacture of scalable electronic products possible - the greater the battery shape changes, the less damaged the function, its more widely used, can be applied to a variety of portable, implantable devices . Of course, before the advent of "flexible" electronic products, scalable batteries have to stand the test of charging and discharging cycles to achieve true commercial applications.
