Education and Research Activities in the Laboratory
Polymers, ceramics and metals are materials used widely in industry from structural to a variety of functional uses. We devote our efforts to develop new functional materials from them to be applied in advanced industry. We focus on the development of biomass-based plastics based on fine controlled polymer synthesis, and all solid lithium battery, for realization of environmental-conscious materials, and next generation electronic, optical, and energy devices. Our laboratory is located in the Osaka Research Institute of Industrial Science and Technology, Morinomiya Center near the downtown area of Osaka city. Our laboratory conducts intimate collaborations with engineers from private companies; this leads to the rapid application of the developed materials into practical devices.Research Themes
1. Biomass polymer materials with unique properties
A group of environmental and functional polymer materials, poly(lactic acid) materials, was developed to obtain properties of similar flexibility, high elongation and transparency to polyethylene, although they were perfectly biodegradable. Additionally, poly(lactic acid) can be synthesized to have high adhesion strength and unique rheological properties, because of high brunch chains and approximately 1 of Mw/Mn.2.All-solid-state batteries fully composed of ceramics
We are engaged in the development of all-solid-state batteries that achieve safety, long lifespan, high power density, and high energy density. We aim to enhance performance through morphology control, including the porous and fibrous structuring of electrode materials, while also focusing on the development of flexible solid electrolytes using inorganic polymerization, organic-inorganic hybridization, and element substitution. Furthermore, we are committed to practical process development, driving research and development that responds to the needs of society and industry.3.Development of next-generation batteries
To improve secondary batteries such as lithium-ion batteries, zinc-air batteries, and redox-flow batteries, our laboratory focuses on the properties and structure of battery components such as electrolytes and electrodes. Correlating them with the electrochemical properties, we develop the battery materials improving high-rate capability and suppressing battery degradation.Explanatory Pictures of Research Activities
