Bendable Thin-Film Battery for Fully Flexible Electronic Systems
A research team from the Korea Advanced Institute of Science and Technology (KAIST) has developed a high-performance, flexible all-solid-state battery, an essential energy source for flexible displays. Professor Keon Jae Lee from the Department of Materials Science and Engineering led the team. Lee's research team developed high-performance flexible lithium-ion batteries (LIB) structured with high-density inorganic thin-films by using a universal transfer approach. The thin-film LIB fabricated on a mica substrate with high annealing temperature is transferred onto polymer substrates through a simple physical delamination of sacrificial substrates. The research team is currently investigating a laser lift-off technology to facilitate the mass production of flexible LIBs and 3D stacking structures to enhance charge density of batteries.
