Research Outline  

Sunlight is almost the only energy source for the Earth where we live. Thus, “how to store and utilize solar energy” is one of the most important issues for achieving a future sustainable society.

I have been studying next-generation rechargeable batteries using multivalent ions such as magnesium. The rechargeable battery is a technological energy-conversion system that can bi-directionally convert electrical and chemical energies. On the other hand, there is a biological energy-conversion system, photosynthesis, which can convert light energy to chemical energy. In this work, focusing on the similarities of the battery and photosynthesis as energy conversion systems, I will develop (i) novel energy conversion/storage devices combining these two systems and (ii) energy conversion science for the interdisciplinary research of biology and technology.

To address the energy and environmental issues, which is a question about the relationship between life and technology, interdisciplinary approaches would be essential. This study aims to open a new field of energy conversion science in the interdisciplinary area between biology and technology for constructing a framework of a future society where people live in harmony with nature.
