Researchers at the Ulsan National Institute of Science and Technology in Korea have developed an imprintable and bendable lithium-ion battery that they claim is the world's first, and could hasten the introduction of flexible smartphones that leverage flexible display technology, such as Samsung's Youm flexible OLED.
Samsung first demonstrated this display technology at CES 2013 as the next step in the evolution of mobile-device displays. The battery could also potentially be used in other flexible devices that debuted at the show, such as a wristwatch and a tablet.
Ulsan researchers had help on the technology from Professor John A. Rogers of the University of Illinois, researchers Young-Gi Lee and Gwangman Kim of Korea's Electronics and Telecommunications Research Institute, and researcher Eunhae Gil of Kangwon National University. Rogers was also part of the team that developed a breakthrough in transient electronics, or electronics that dissolve inside the body.
