World's First Imprintable and Bendable Li-ion Battery Created

By - Source: Yohap News | B 18 comments

Technology makes batteries bendable, as well as making the process in doing so more stable.

Bendy Battery


Korean researchers have uncovered a process to create "a class of imprintable, bendable, and shape-conformable polymer electrolyte with excellent electrochemical performance in lithium battery system."

The material can be sprayed on electrodes and then baked with UV rays for about 30 minutes in order to create power units, which would provide a method considerably faster than the standard way of creating lithium-ion cells.

Professor Lee Sang-young from South Korea's Ulsan National Institute of Science and Technology is the head of the project, who is working with nine additional scientists from different institutions such as Professor John A. Rogers from the University of Illinois.

"Conventional lithium-ion batteries that use liquefied electrolytes had problems with safety as the film that separates electrolytes may melt under heat, in which case the positive and negative may come in contact, causing an explosion," said The Korean Ministry of Education, Science and Technology, which is co-sponsoring the research.

"Because the new battery uses flexible but solid materials, and not liquids, it can be expected to show a much higher level of stability than conventional rechargeable batteries."

During CES, Samsung unveiled Youm, a flexible and bendable OLED display for smartphones.

    Some laptops and smartphones also need those. Nobody likes burning silicon in their pockets or on their lap.

    They can't patent the technology itself, but they'll patent using it in a smartphone, tablet, or laptop.

    Scratching the case soon has an entirely new meaning...

    Enough with the teasers, release them to the consumer market now.

    that would be cool, charged by body heat.

    ok... here is the million dollar question

    what is the puropse of this outside of we can do it?

    They're probably scrambling to find that patent buried in the mountains of other patents. Sadly, what they don't know is, Apple never had one. But with so many, they got to have it, it's in there some where. And so the desperate search continues...

    means you can fill any empty space in the device with a battery extension ...

    the main problem of the batteries is that they must have rectangular fixed place empty ...

    now you can "squeeze them where ever u want ... and make the Battery itself into shapes and different thicknesses

    snameans you can fill any empty space in the device with a battery extension ...the main problem of the batteries is that they must have rectangular fixed place empty ...now you can "squeeze them where ever u want ... and make the Battery itself into shapes and different thicknesses

    the bigger problem is they put a good enough battery in the devices, and try to make them thinner. sure, devices use less power now, but they are also thinner and get lesser and lesser batteries.

    i can see this allowing even thinner devices, but at the same time, getting lesser battery space as a result, and having them be just good enough.

    besides cramming more battery into space, is there any other application?

    Dear God, Zak. Please go back to school and learn how to write.

    I'm not trying to be a smart ass, but I don't know what you mean by "Imprintable". I've looked at my dictionary, Dictionary.com, and Wikipedia, and I do not see such a word. There is a word imprint, but how does that relate to this? In one sense you claim they are spraying stuff on, like layer deposition technology; however, what does that have to do with imprinting?

    You could put a battery pretty much anywhere with this. In your clothes, on your wrist, you could carry around a laptop bag/briefcase made out of a battery. Combine that with wireless charging and it opens up a lot of options for mobile devices! I like!
