Membrane Lab

Young Moo Lee, Ph. D.

http://mbl.hanyang.ac.kr/
Membrane Laboratory (MBL) has focused on the development of advanced polymer materials for membrane technology, which is versatile green technology applicable to environmental separation process and energy converting/ harvesting process. In membrane Laboratory, membrane materials have been designed for porous polymer membranes for gas separation and water treatment membrane as well as various ion exchange membranes for energy harvesting /converting process including polymer electrolyte fuel cell (PEMFC). These invented polymers innovate the conventional membrane technologies, creating new membrane applications and growing membrane markets. For gas separation process, thermally rearranged (TR) polymers, tuned with hourglass-shaped subnano-sized cavities, showed extraordinary carbon dioxide permeability over 500 times larger than the conventional gas separation membranes. Based on this novel concept on TR polymers, various molecular designs of TR polymers are currently ongoing with various monomers to improve gas separation performance by specifically tuning cavity size and distribution, in collaboration with international partners (Air Products, CSIRO, CSIC). TR polymer hollow fibers are also being commercialized by Air Products (US) via technology transfer. For energy converting process, self-humidifying membranes, regulating the water content, exhibited outstanding PEMFC performance in high temperature and low humidity condition because of nano-crack formed by plasma treatment. (Nature, 2016) These achievements of MBL were published in over 380 original papers including Science and Nature and over 100 patents during the last 25 years, which have been cited over 25,000 times.

Research in our laboratory focuses on the development of next-generation processing technologies such as synthetic technologies of 1-dimensional nanomaterials (silicon, carbon, LiFePO4, ZnO, GaN), patterning technologies of nanoscale functional materials through controlling interparticle force of nanoparticles, and transfer technologies. These processing technologies can be applied for the fabrication of novel nanoelectronics such as transparent displays, energy storage devices including lithium ion batteries and solar cells, and stretchable and flexible device. For fabricating stretchable and flexible device, we collaborate with John A. Rogers group in UIUC In the energy storage part, we focuses on designing novel electrode for high capacity and high power lithium ion battery applying the synthetic technologies of 1-dimensional nanomaterials (Silicon, Germanium, Cabon Nanotube, Transitional metal oxide). And international collaboration research is performing for lithium-air battery with Prof. Linda F. Nazar in Waterloo University. We interested in designing ceria slurry through control of dispersion and chemical additive for chemical mechanical planarization beyond 50nm in NAND flash memory. A part of gas-turbine research, we have developed thermal barrier coating fabrication technology for improving thermal insulating, durability, and abrasion resistance. Additionally, we also research about ceramic core fabrication technology for forming cooling path in blade and vein. As a result of such research, we published about 300 papers in international SCI journals.

Advanced Electrochemical Technology Lab

Hansu Kim, Ph. D.

http://hkim.hanyang.ac.kr/aetl
Advanced electrochemical technology lab (AETL) has studied in electrochemical system and rechargeable battery since 2011. In AETL all members impassionedly discover new materials for electrode and new kind of electrochemical system. In present, we focus on "Anode materials for Rechargeable battery", "Inorganic electrolyte-based Rechargeable battery", and "New cation storage site in the nanostructured materials". AETL develops high capacity and stable Si based nanostructured material as an anode material for LIB to substitute present graphite because Si has 10 times higher theoretical capacity than that of graphite. However, Si has huge volume expansion during cycling and it is critical point to be treated for commercial usage. To reduce the volume expansion and secure its stable cycle performance, we focus on the developing of Si/SiOx, Si-Metal alloy, and porous Si, and simple route to synthesize them. And we have revisited the possibility of SO2-based inorganic liquid electrolyte. This electrolyte has many attractive features such as non-flammability, high ionic conductivity, and low-temperature operation. By applying these advantages to the nanostructured carbonaceous materials, the alkali metal (Li, Na, and etc) anode materials, and various transition metal compounds, we found a new mechanism with excellent electrochemical properties. This research can provide a route for further research direction to explore a variety of SO2-based inorganic rechargeable batteries system. We also investigate to develop nanostructured material such as nano-sized transition metal oxides as an electrode material for LIBs and SIBs. It is well known that nanostructured materials provide unusual physical and chemical properties, compared to bulk material. We cooperate with research teams of universities and companies worldwide, to achieve higher and detailed goals of research within extended range of intellectual partnership.
