Elucidating the fundamental Mechanism of Electrode Reactions in Lithium Secondary Batteries and Fuel Cells and Developing New Materials
Electrochemical energy conversion systems, such as lithium secondary batteries and fuel cells, are clean, highly efficient systems that can serve as a key solution to effective use of fossil fuels and environmental problems facing our society in the 21st century. Such energy conversion systems can be used as power supplies for hybrid electric vehicles, distributed energy storage systems for electric-load leveling, or cogeneration (or combined heat and power) units for home use. With an aim of achieving higher performance and enabling earlier commercialization of such energy conversion systems, our research focuses on elucidating the fundamental mechanism of electrode reactions used in such systems and developing new materials.
1)Lithium-Ion Batteries:
Large lithium-ion batteries for electric vehicle power sources and for distributed energy storage will need drastic improvement in energy density, power density, durability, and safety to allow their practical use. To develop such high-performance batteries, our group is actively engaged in developing silicon negative-electrodes, 5 V class positive-electrodes and highly stable electrolyte solutions, as well as analyzing the fundamentals of electrode reactions with in-situ analysis methods, such as Raman spectroscopy and atomic force microscopy (AFM).

2) Fuel Cells:
To allow widespread use of polymer electrolyte fuel cells (PEFCs), our laboratory, in a collaborative research project with industry and government, is developing core-shell type Pt catalysts that would reduce the use of platinum in cathode catalysts. Ammonia is a promising hydrogen carrier in the hydrogen energy society. We are also engaged in developing ammonia-fueled solid oxide fuel cells (SOFCs) operating at high temperatures lower than 500 °C for use in electric power plants and fuel cell vehicles.
