Rapidly-growing flexible/wearable electronics with unusual shape diversity and mobile usability have garnered considerable attention as a game-changing technology to bring us unprecedented innovations. As power sources are concerned, conventional rechargeable batteries with fixed shapes and dimensions have intrinsic limitations in meeting the aforementioned design/performance requirements. In this talk, as an efficient strategy to address this challenge, I’ll present a new class of aesthetically-versatile Li-ion batteries. By using simple cell fabrication process (specifically, based on printing followed by ultraviolet crosslinking), major battery components are consecutively printed on arbitrary objects of complex design and geometries, eventually leading to multilayer-structured printable batteries with various form factors far beyond those accessible by conventional battery technologies. Uniqueness in materials/structure/processing will be comprehensively discussed and correlated with battery performance, with a particular focus on design versatility. |
