제목 Reentrant Graphene/Carbon Nanotube-Melamine Micro-cellular Foam Electrode for Stretchable Lithium Metal Batteries
초록 Recent advances in wearable electronic devices demand stretchable energy storage systems with high-energy-density. Lithium metal has been considered as one of the most promising anode materials because of its high theoretical capacity. However, stable deformation of such metal electrodes is constrained within a very confined value due to innate limit of mechanical deformation for solid materials. Here we present stretchable and conductive melamine foam based microstructured electrodes for stretchable lithium metal batteries. The highly porous and elastic open-cell melamine foams were filled with micro-celluar structures with reduced graphene oxide (rGO) and carbon nanotube (CNT) by directional freezing method. After a reentranting process, such hierarchical structures have advantages in elastic deformations with maintenances of high electrical conductivity. Lithium can be plated on the rGO/CNT surfaces via electroplating method for the anode applications.
