초록 | Secondary ion batteries and various type of supercapacitors represent an important class of energy storage devices because of their high power density with a high energy density. A remarkable improvement in performance has been achieved through recent advances in the development of advanced materials. Especially, their novel structural properties as the electrode materials, such as abundant active sites and high ion accessibility, are important to realize a high capacitance with robust cycle life in electrochemical capacitor applications. In this seminar, I will discuss my recent research activities on development of carbon nanostructure having multi-porosity for electrochemical energy storage with high performances. Through various synthetic conditions, we fabricated the unique structures, in which internal compartments enable the accommodation of numerous active nanoparticles. Nanoparticles embedded nitrogen-rich porous carbon composite was assembled with nitrogen-rich porous carbon nanostructure itself into full-cell hybrid capacitor devices having an excellent rate capability and robust cycle life. Furthermore, by using the instant polymerization process, a hierarchical graphene pliable pocket was fabricated with the internal compartment to accommodate anode materials with high energy densities, which is also extended to a scalable mass production by simply increasing the batch size. We conclude that many structural advantages such as small size, porosity and ion pathway play a role as the key to success in designing the next generation energy storage devices with high energy and high power densities. |
