LEMP (Laboratory for Electrode Material Properties) is focused on the discovery of advanced electrode materials for fuel cells, lithium secondary batteries, and various P2G (power to gas) systems such as water electrolysis and CO2 conversion. In addition, fundamental studies are conducted on the corrosion/anti-corrosion and the metallurgical processes based-on electrochemistry.
Fuel cells and P2G systems
- Electrocatalysis for hydrogen oxidation reaction (HOR) and oxygen reduction reaction (ORR) for proton exchange membrane fuel cells (PEMFCs) and anion exchange membrane fuel cells (AEMFCs)
- Electrocatalysis for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) for proton exchange membrane water electrolyzers (PEMWEs) and alkaline water electrolyzers (AWEs)
- Electrocatalysis for carbon dioxide reduction reaction (CDRR) and nitrogen reduction reaction (NRR) for power to gas (P2G) systmes
Lithium secondary batteries
- Transition metal doped high-Ni cathode materials (NCA, NCM, NCMA, etc) for electric vehicle applications
- Synchrotron studies for analyses of lattice structure in long-range order (HRPD) and short-range order (EXAFS), and electronic structure in occupied state (HXPES) and in unoccupied state (XANES)
- Hydrometallurgical processesbased on solvent extraction to collect the active materials such as Ni, Co, Mn from ores or battery recycling
Electrochemical corrosion and anti-corrosion
- In-situ electrochemical and spectroscopic methods for fundamental studies on corrosion and anti-corrosion in commercial steel products
- Anti-corrosion approach with surface coating of thin film by using RF magnetron sputter, E-beam evaporator, atomic layer deposition and electroplating
