In Celebration of the 2019 Nobel Prize in Chemistry


JEOL Ltd. (Chairman & CEO: Gon-emon Kurihara, President & COO: Izumi Oi) would like to sincerely celebrate the winning of Nobel Prize in Chemistry of Dr. Akira Yoshino, Asahi Kasei Honorary Fellow for the development of Lithium Ion Rechargeable Battery and express our respects to Dr. Yoshino for his great research endeavor for many years.

The Lithium Ion Rechargeable Battery is inevitable in our daily life now. The prototype was invented in 1983 for the first time by Dr. Yoshino and others, by using the conductive polymers invented by Dr. Hideki Shirakawa, Professor Emeritus and a winner of 2000 Nobel Prize in Chemistry, as a cathode, and the lithium cobalt oxide, a compound of lithium and cobalt oxide, found by John B. Goodenough, Professor of the University of Texas, USA, who has been jointly awarded the Nobel Prize in Chemistry, as an anode.
Dr. Yoshino and other professors made further improvements and established the fundamental concept of Lithium Ion Rechargeable Battery using carbon material as cathode in 1985. Also, they have developed various technologies which were essential for Lithium Ion Rechargeable Battery, such as a functional separator to ensure the safety in commercialization of the LIB. Our NMR (Nuclear Magnetic Resonance Spectrometer) has also been utilized in these researches, which is nothing but a great honor for JEOL Ltd. Above all, on the study of lithium ion behavior in polymer, Dr. Yoshino has contributed a paper in the technical journal of JEOL Ltd.

JEOL Ltd. would like to celebrate the Nobel Prize winning of Dr. Yoshino and is determined to continue developing instruments and technologies that can contribute to this field.


    Dr. Yoshino, Asahi Kasei Honorary Fellow, has contributed a paper in our technical journal “JEOL News” Vol.46, 2011.
