From the viewpoints of a sustainable and environmentally friendly society, electric vehicles and fuel cell vehicles have attracted increasing attention. The education and research of the Advanced Material and Chemistry field are related to advanced materials including inorganic, organic, polymeric and metallic substances, which contribute to high performance, weight saving and durability of the components in automobiles. The research area of this field covers lithium-ion batteries, fuel cells, rechargeable batteries, capacitors, electrical storage devices, catalysts for decomposition of automobile exhaust gas, polymer nanocomposites, filtration membranes, coatings, adhesives, solar cells, semiconductor power devices and hydrogen sensors. The above-mentioned materials designed by precious chemistry and physics should promote the development of next generation automobiles.
Development of new concept fuel cell are required for vehicle with high efficiency. New materials for solid oxide fuel cells are studied for decreasing operating temperature and increasing reliability. In particular, direct hydrocarbon type SOFC is mainly studied. On the other hand, metal-air battery is similar structure with fuel cells, and expecting as large capacity rechargeable battery. Highly active and reversible air electrode catalyst for Zn-air and Li-air battery is developing.
For wide use of diesel engines, removal of nitrogen oxide (NOx) and particulate matter (PM) is strongly required from environmental issues. Development of new de-NOx as well as low temperature PM oxidation catalyst is developing by using perovskite oxide. Application of catalytic technology for next generation automobile will be studied.
The target of Okada Lab is to develop low-cost, high-efficiency large-size rechargeable batteries. In the evolutionary diagram (Figure) of the batteries, as the hybrid type new battery between NiMH and Li-ion battery, we found that the aqueous Li-ion battery with the cheapest Fe-based LiFePO4 cathode and the 2nd cheapest Ti-based LiTi2(PO4)3 anode in 2007. On the other hand, as the hybrid type new battery between NAS (Na/Sulfur) and Li-ion battery, Na-ion battery with metal-free disodium rhodizonate was developed in 2013. And as the hybrid type new battery among them, aqueous Na-ion battery with Na2FeP2O7 cathode and NaTi2(PO4)3 anode and aqueous Mg-ion battery with MgMnO2 cathode and anthraquinone organic anode were also proposed as the high cost-performance next generation battery.
Our research object is to discover novel functionalities of organic polymeric materials by understanding and controlling structures and properties of the polymeric materials at the molecular level. Such research leads to the development of composite materials for interior parts and exterior parts of vehicles and tires. We conduct experiments in our laboratories, collaborate in research with a number of domestic and overseas companies, research institutions and universities, and if necessary we use large facilities for radiation and neutron experiments.
We are working on materials to stop the global warming and for renewable energy. For example, new solar cell fabrication process, new technology on hydrogen gas sensing using ultrasonic, hydrogen storage and generation, novel power device fabrication, application on phosphorescence material, etc. are studied. The picture is our new prototype hydrogen sensor using ultrasonic.
We conduct experiments related to organic functional materials including hydrogels, micelles, liquid crystals and colloids. One specific goal is the understanding of how local physical properties including their spatial heterogeneity are related to the macroscopic physical properties. Such approach should lead to the development of functional materials that is useful for the components in automobiles such as composites and adhesives. Another objective is the surface engineering for regulation of wettability and friction, which contribute to the coatings for automobiles, on the basis of a dynamic nature of organic (macro) molecules.
