Bendable battery yields flexible LED

摘要

Thanks to an energy-dense flexible lithium-ion battery, researchers have built a thin, bendable light source using an organic light-emitting diode (LED). The device could one day be incorporated into reliable or implantable electronics.Lithium-ion batteries are among the best candidates for flexible power sources, but their electrodes could previously be made with only a few, low-performing materials. Now, Keon Jae Lee at the Korea Advanced Institute of Science and Technology in Daejeon and his colleagues have created a bendable battery by using existing methods to apply lithium-based electrodes onto a brittle mica surface at high temperature and then peel off the mica substrate.
