Following the ceremony, Prof. Yoshino gave a special lecture before an audience of 1,311 attendees at Kyushu University Energy Week 2020. After congratulatory addresses from Kyushu University President Kubo and Prof. Michitaka Ohtaki, Director of the Research Center for Green Technology, Prof. Yoshino spoke on environmental issues and how they relate to his research, explaining the development of the lithium-ion batteries that would eventually win him the Nobel Prize. He went on to talk about his ideas for achieving a sustainable society, explaining that he believes we will see an energy technology revolution by the year 2025—a revolution that seeks to combine environmental sustainability, economy, and convenience.
In the Q&A session that followed the lecture, Prof. Yoshino revealed that his lithium-ion battery research started around age thirty-three when he gained more perspective and enough autonomy to take chances. Professor Yoshino encouraged students to invest in their future selves now, saying, “Your mid-thirties are the best time in your life to do something new, since you have a good deal of perspective but still have time to bounce back even if you fail.”
In 2015, Prof. Yoshino was appointed a visiting professor at the Research and Education Center for Advanced Energy Materials, Devices, and Systems, the predecessor to the current Research Center for Green Technology, located on Kyushu University’s Chikushi Campus. Since then, he has come numerous times to speak and lecture, but this time, in light of his Nobel Prize in Chemistry, he gave an especially memorable lecture for the Chikushi Symposium, an event held annually during Kyushu University Energy Week.
