Koreans have created a flexible battery

Korean specialists did ultra slim flexible battery. This invention in the near future may lead to the emergence of "folding" devices with a large display that can be folded and put in your pocket, or, for example, to the appearance of "television" wallpaper with a touch display.

It’s no secret that the relatively inconvenient use of portable electronics is the relatively small display size. In the final analysis, there is always a rational size limit: the device should be comfortable to carry. However, devices that can be rolled up into a tube are, of course, a completely different story.

A couple of years have passed since the time when the tablets appeared. But since then, the portable electronics industry has not demonstrated anything fresh in principle, except for cosmetic configurations and capacity building. Perhaps the latest revolution on the market will be precisely the flexible devices that squeeze out the “tablets," as they once replaced netbooks.

Elastic display technology was created a long time ago. A few months ago, Atmel demonstrated XSense technology, which allows the creation of “bendable” touch displays, and Samsung in 2011 showed the world flexible OLED displays that work on organic light emitting diodes (there, each pixel itself emits light). In addition, this year Nokia decided to register a patent for a flexible phone, which can be wrapped around the wrist as a decoration.

Transparent batteries for mobile phones have already been created, and flexible gadgets have not yet become widespread. Despite the fact that elastic displays have already been invented, the batteries so far have not been able to make bendable. Thanks for the development should be Professor Ken Jae Lee and a team of scientists from the Korean Institute of Science and Technology. The specialist was able to do flexible lithium ion battery as thin as a razor and, most importantly, retaining tension even when bent.

As shown in the video, a flexible battery drives a battery connected to it. LED light bulbAt the same time, no matter how the energy store bends, the light does not blink. This means that the voltage remains stable, which is confirmed by the multimeter.

Professor Lee is currently exploring the possibility of mass production. flexible batteries. He is also working on connecting several batteries, which will provide the opportunity to provide significant power. But while the capacity of flexible batteries is not very large. However, the improvement is moving rapidly and, most likely, in the near future, flexible batteries will become an ordinary part of many devices.
