제목 : Textile Electrodes for Boosting up Areal Energy Performance 

 

내용 : Charge transfer between a conductive support and active materials as well as between neighboring active material is one of the most critical factors in determining the performance of various electrodes in energy harvesting, conversion, and/or storage. Particularly, when preparing energy storage electrodes using conductive and/or electrochemically active nanoparticles (NPs), the bulky organic materials (i.e.,ligand of polymeric binder) covering the surface seriously limit the charge transfer within the electrode, thereby restricting the energy storage or conversion efficiency. Furthermore, the flexibility and mechanical stability of the electrode have been considered important evaluation indices for flexible/wearable energt applications. 

In this regard, considerable research has been directed towards controlling the interfacial structure to enhance the charge transfer efficiency and towards incorporating functional materials into flexible/porous supports. This study describes the central progress in flexible electrodes for energy storage devices, along with the challenges in designing high-performance energy electrodes. In particular, we focus on layer-by-layer(LBL) assembly, which is an ultrathin film fabrication technology that enables fine tuning of the interfacial structure for various electrode materials.
