Researchers from South Korea’s Ulsan National Institute of Science and Technology have developed what appears to be the world’s first imprintable and bendable lithium-ion battery. This could help speed up the production of smartphones with flexible displays, such as Samsung’s Youm flexible OLED display, to say the least. According to South Korea’s Ministry of Education, Science and Technology, the batteries use nanomaterials which can be applied to any surface to create fluid-like polymer electrolytes.
The technology does not only make the batteries bendable, but the process also makes it more stable. “Conventional lithium-ion batteries that use liquefied Electrolytes had problems with safety as the film that separates the electrolytes may melt under heat, in which case the positive and negative may come in contact, causing an explosion,” the department said. “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.”
