Outline Activities
Prof. Hayashi’s group covers the field of Applied Inorganic Chemistry, including synthesis of novel functional ceramic materials, and fundamental researches based on solid state chemistry and physics. They are studying not only typical metal oxide-based ceramics but also novel mixed-anion compounds with nitride, hydride, and electride. Materials functions such as ionic conduction/exchange and dielectric/conductive properties are applied to development of energy storage and electronic devices. In particular, they are interested in materials that contribute to the development of innovative energy storage devices and their composites.

- Development of sodium ion batteries using elements with no resource constraints with the goal of achieving high energy density and long life.
The lithium-ion battery, which was first commercialized in Japan, has the highest energy density of any practical storage battery and is therefore indispensable for the realization of GX technology. However, they require rare and toxic elements, and the price of lithium raw materials has been fluctuating wildly due to the uneven distribution of lithium resources. High-cost cobalt, nickel, and copper are also required. As the range of storage battery applications expands and efforts to address environmental and energy issues on a global scale become more important, the development of lithium-substitute storage batteries free from geopolitical risks and resource constraints is one of the most important issues in innovative GX technology. In this R&D, we will focus on sodium, which is the same family as lithium in the periodic table and has no resource constraints, and work on materials development, battery design, mechanism analysis, and computational science research for social implementation of the next-generation storage battery "sodium ion battery" that inherits the lithium-ion battery technology originated in Japan. In particular, Professor Hayashi's group will be responsible for the development of an all-solid-state oxide storage battery that inherits the features of the sodium ion battery.

Educational
Educational Activities
Professor Hayashi is in charge of lectures mainly in the field of inorganic chemistry in basic education, undergraduate education, graduate education, and their international courses. Through the activities of the Japan Engineering Education Association and the Kyushu Engineering Education Association, he will also contribute to high school and university education from the perspective of Kyushu, as well as to entrance examinations and curricula in the Faculty of Engineering. As a researcher and educator, He will convey the interest and importance of inorganic materials and ceramics through lectures on traditional ceramics, cutting-edge industrial components and products, related resource and environmental issues, and solid state science combined with high school physics and chemistry in a way that is easy to understand.
